Summing Up<\/strong>
\nI don\u2019t want to imply that digital sound is taking over, or that tube and solid-state equipment are not still competitive, or that integrated amplifiers will become the wave of the future. I do believe, however, that the SU-R1000 is truly competitive and an excellent buy, even at its price.\u00a0<\/span><\/span><\/p>\n

One of the potential curses of being a reviewer is that you\u2019d like to keep every really innovative and great-sounding piece of equipment you audition, along with all your existing equipment. One of the benefits is that you realize there is no one right answer, and that even equipment that is decades old can still be exciting and \u201creference quality\u201d in its ability to let you enjoy your music.<\/span><\/p>\n

I do believe, however, that the Technics SU-R1000 lives up to all its claims. It is truly innovative, and should help rebut any lingering prejudice against both digital and integrated amplifiers. Accordingly, I\u2019d give the same kind of recommendation that the\u00a0Michelin Guide<\/i>\u00a0gives to its few top-rated three-star restaurants: They are all different, but they are also all \u201cexceptional and worth a special journey.\u201d The SU-R1000 is the kind of product that makes the high end fun!

To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and re-quantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These technologies enable Technics digital amplifier designs to reproduce the natural and delicate nuances of music.ADCT(Active Distortion Cancelling Technology)Circuit Diagram of Digital Amplifier TechnologyThe Active Distortion Cancelling Technology newly developed by Technics accurately extracts and removes distortion in the power output stage which is generated by the speaker\u2019s counter electromotive force and voltage drops. In the Hi-Fi audio market where an unlimited number of audio systems can be configured by combining various products, high-end audio amplifiers need to optimally drive a diversity of speakers. The Active Distortion Cancelling Technology accurately extracts distortion by determining the difference between the speaker terminal output and JENO output and then applies correction to the output digital signal, thus correcting the conventional digital amp system. This provides powerful speaker driving force and acoustic energy while offering the superior benefits of a digital amplifier, such as low noise, precise sound image and expansive sound ambience, regardless of the types of connected speakers.Advanced Speed Silent Power SupplyGraph of Super High Speed Switching Power Supply Picture of GaN-FET(left) and SiC Diode(right)The SU-R1000 uses a switching power supply system to ensure a stable supply of voltage and current required by the digital amp. In a conventional switching power supply system, the ON time of the switching operation was controlled in order to stabilise the voltage, and this causes the switching frequency to fluctuate according to the load, resulting in a modulation noise to affect the sound quality. The Advanced Speed Silent Power Supply has eliminated this noise by fixing the switching frequency in the 400kHz band. Furthermore, a Super Low Noise Regulator is provided in the later stage. This prevents the decrease of regulation resulting from the fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a high-response power supply that results in the best performance from the digital amplifier.Four Independent Power Supply UnitsPicture of Pre AmplifierIn the SU-R1000, every element comprising the power supply has been diligently studied and revised for higher sound quality. What\u2019s more, four independent power supply units are provided for different circuit blocks for further enhancement of sound quality. Since the SU-R1000 is an integrated amplifier, the internal circuits consist of a pre-amp stage and power amp stage in a mix of analogue and digital circuits. The Phono-EQ section which processes minute analogue signals is particularly susceptible to the effect of noise transmitted through the power supply line. The SU-R1000 uses separate power supply units for the analogue circuits and digital circuits in the pre-amp stage. It also uses separate power supply units for the right and left channels in the power amp stage that requires large electrical power. With the four independent power supply units, the SU-R1000 prevents power-line-induced interference among the circuit blocks and realises a high S\/N ratio and superb separation.High-grade Digital\/Analog I\/O CircuitPictures of component parts for High-grade Digital\/Analog I\/O CircuitThe phono input section and analogue input section feature a full-discrete circuit design. Technics has realised an ideal, symmetrical circuit layout and performed meticulous tuning. The new circuits prevent interference between the right and left channels and achieve excellent channel separation. Furthermore, the phono input section and XLR input section employ completely balanced transmission to ensure high-purity signal transmission with minimum effect of noise. The USB input circuit in the digital input section is equipped with a capacitor of high-quality ruby mica and a power conditioner with nonmagnetic carbon film resistors for blocking electrical noise e.g. from a PC and for minimising the effect of external noise. The A\/D converter incorporates a high-performance chip made by Asahi Kasei Microdevices (AKM) for high-precision A\/D conversion. Thus, the SU-R1000 reproduces outstanding sound quality from any analogue or digital input sources.High Rigidity Chassis and DesignPicture of High Rigidity Chassis and DesignThe rigidity of the chassis has been enhanced extensively to suppress the enclosure vibration that is also a source of noise. The inner chassis features a double-deck separated structure. Mounted on the upper deck is the power amp section consisting of the amplification circuit and its power supply circuit. Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates. They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels.Input and output terminals made of meticulously selected high-quality parts- Speaker terminals designed to allow connection of extra-large diameter speaker cables- Y-lug terminals for ensuring reliable cable connection- Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC)- Analogue input terminals with gold-plated, machined brass partsTechnics\u2019 refined design- Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter- Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finishedCrosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridgeGraphic of Crosstalk CancelerThis function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000.

It shows how quickly digital sound is evolving and provides an exceptional mix of well-engineered features in a single integrated unit\u2014drawing on much of the technology used in the Technics SU-R1 reference system that Alan Taffel review in the October 2016 issue of TAS. What really counts from an audiophile perspective, however, is that the SU-R1000 provides excellent sonics from both its digital and analog inputs, as well as offering some unique advantages in terms of cartridge equalization and sound quality in its phono front end. The SU-R1000 also has the ability to use digital processing and test tones to improve its interface with a given speaker and listening room. At $9499, the unit is scarcely cheap, but it is still highly competitive at that price, and it offers a uniquely compact package for the electronics that make up a high-end system.I\u2019m giving this integrated the praise its designers and engineers deserve at the start because I\u2019m going to go on to raise a number of issues about the manufacturer\u2019s technical data and instructions\u2014none of which affects its practical operation and sound quality. With proper attention to setup, the SU-R1000 provides a remarkably uncolored sound, and exceptional detail, dynamics, and overall performance. Technics SU-R1000 Integrated Amplifier rearThe SU-R1000 has no clearly audible colorations that affect its frequency response or performance from the lowest levels of amplification to the limits of its 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. If anything, it may be too uncolored for some audiophiles. It has no voicing other than a clear effort to be as neutral as possible. If you use electronics that are voiced to add a touch of euphony to your system, you\u2019ll have to give the SU-R1000\u2019s other virtues priority. As for functionality, about the only practical limit I encountered is that it does not have built-in streaming, although it can handle any PCM signal from 32k to 384k up to 32 bits, and a full range of DSD signals, as well. Its digital sound quality rivals that of some of the best DACs, particularly in terms of life and dynamics, soundstage coherence, and timbral fidelity. It does very well with MQA, although I still prefer using actual high-resolution signals when the music truly has high resolution than reprocessing the source using higher sampling and bit-rates.I should also note that there is another reason I\u2019m placing this praise for the SU-R1000\u2019s sound quality at the start of this review. I realize that a number of American and European high-end audiophiles have a lingering prejudice against Japanese products, particularly from firms like Technics, which make mass-marketed mid-fi as well as high-end gear. So, let me make it clear: This is no ordinary product, and some of its special features truly are special. More than that, whatever your current view may be of \u201cdigital sound,\u201d this unit really is worth auditioning. This is particularly true with a dealer who will actually demonstrate what its phono-cartridge optimization and equalization and its Load Adaptive Phase Calibration (LAPC) amplifier can do to make subtle but very real improvements in interface, speaker optimization, and sound quality.Pages: 1 2 3 4 5 6 7Tags:INTEGRATED AMPLIFIERTECHNICSMost PopularThe Ten Most Significant Amplifiers of All TimeThe Ten Most Significant Amplifiers of All Timeby TAS Staff Apr 01st, 2011top_50_202050 Greatest Bargains in High-End Audioby TAS Staff Dec 14th, 2020rega_p6Rega P6 Turntable, RB330 Tonearm, Neo PSU, and Ania Moving-Coil Cartridgeby Wayne Garcia May 06th, 2021Check out our selections for loudspeakers2021 Editors\u2019 Choice Awards: Loudspeakers $10,000 \u2013 $20,000by TAS Staff Mar 30th, 2021 TopBACK TO TOPBy Anthony CordesmanMore articles from this editorCat IconREAD PREVIOUSThe End of An Era: RIP Rocky Mountain Audio FestTechnics SU-R1000 Integrated AmplifierREAD NEXTTechnics SU-R1000 Integrated AmplifierRead Next From ReviewSEE ALLClearaudio Concept Dark Wood Active TurntableREVIEWClearaudio Concept Dark Wood Active TurntableIt\u2019s easy to think of turntables from only a single [\u2026]by Neil Gader Aug 31st, 2021DS Audio Grand Master Cartridge and Grand Master EqualizerREVIEWDS Audio Grand Master Cartridge and Grand Master EqualizerIt seems like it was only yesterday that I rave-reviewed [\u2026]by Jonathan Valin Aug 25th, 2021My_Sonic_Labs_Signature_Gold_MC_Cartridge_Angle_Left_FrontREVIEWKoetsu Rosewood Signature Platinum & My Sonic Lab Signature Gold Moving-Coil CartridgesAlthough my wife and I are longtime fans of Japanese [\u2026]by Wayne Garcia Aug 24th, 2021Luxman D-10XREVIEWLuxman D-10X CD\/SACD Player and DACSome thirteen years ago I reviewed a pair of Luxman [\u2026]by Paul Seydor Aug 16th, 2021Sign Up To Our NewsletterName*Your NameFirstEmailYour EmailConsent* I have read and agree to the terms and conditions*BrandsThe Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation.Martin Logan Paradigmhttps:\/\/images.theabsolutesound.com\/wp-content\/uploads\/2020\/09\/logo-white.pngThe Absolute Sound is the world\u2019s preeminent source of expert reviews, features, and commentary on high-performance audio and music.SUBSCRIBEMAGAZINEAbout usShopAdvertiseBack IssuesCONNECTFacebookInstagramYoutubeContact via EmailJOIN OUR NEWSLETTEREmailEnter Your Email HereTerms and conditions Privacy Community GuidelinesCopyright \u00a9 2021 The Absolute Sound.

I also realize that most readers are far more interested in descriptions of the sound quality of a given product than in descriptions of its technology. However, the SU-R1000 has so many additional features and new areas of circuit topology that they really are worth exploring. Even if you are only interested in the overall development of digital high-end products, and how they can be used to improve sound quality, you will find reading about Technics\u2019 tech and features interesting enough to visit the manufacturer\u2019s web site. The text printed there does suffer from all of the usual marketing hype\u2014sometimes making the real level of engineering progress unclear\u2014but the SU-R1000 white paper gets many key points across. It also illustrates how meaningless it can be to call a modern switching amplifier \u201cClass D\u201d instead of getting into the design details. The SU-R1000 has a switching output stage, but one that is driven by digital signals. Digital sources are converted to analog in the switching output stage without the need for analog circuits or a traditional DAC. I\u2019d pay particular attention to the description of the JENO (Jitter Elimination and Noise-shaping Optimization) Engine, ADCT (Active Distortion Cancelling Technology), LAPC (Load Adaptive Phase Calibration), Advanced Speed Silent Power Supply, use of four independent power supply units, the battery-driven clock generator, and, especially, the Intelligent Phono EQ. The descriptions are technically vague as to the \u201chow\u201d and full of details about exactly what they do to improve sonics, but the website gets the main points across, and it provides an interesting checklist for comparison with what other competitive integrated amps do\u2014or do not do\u2014in each area.Technics SU-R1000 Integrated Amplifier interiorYou also get a clear idea from the pictures in the Technics literature of how well the SU-R1000 is built, and how clean its \u201cform follows function\u201d design really is. There can\u2019t actually be a Japanese version of \u201cBauhaus\u201d industrial design at Technics, but there are obvious elements of that purist approach, and of the effort to create an appearance that borders on sculpture, in the SU-R1000. I also can\u2019t avoid a personal addiction to the large illuminated VU meters in the front panel that show nominal wattage. It might well have been better to provide an LCD that made the menu easier to use, and the resulting set-up status clearer, but if that had been the case the SU-R1000 wouldn\u2019t have come anywhere near as close to being a work of art.There are also some practical aspects of the SU-R1000 that deserve attention. This is one of the best-engineered products I\u2019ve ever reviewed, but it also has one of the worst instruction manuals. It skims over far too many details\u2014like the character of the tone controls and phono equalization options. But more than that, the remote is designed for command-driven setup and adjustment, as well as ordinary operation. Many of those commands involve fairly complex sequences, which have to be carefully keyed-in using the small screen on the remote\u2019s front panel. I\u2019m a Mac person, not a PC person, and I found the manual to be a bit fuzzy on the proper order of commands, and it took me a day of so to get used to the remote. In fact, I had to experiment at times to figure out what the actual sequence was. This manual for the SU-R1000 is available for download, and there are many areas where Technics could provide a clearer picture of what to do, what actually happens when a given command is followed, and what to listen for. Technics does have some additional information sheets on the web that help with this, but having a couple of pages each that cover LAPC and phono-cartridge optimization in real depth, and that explain each control and feature in real depth, would be better. So would providing in-depth instructions on using other Technics equipment\u2014and that from other manufacturers\u2014for streaming and for using the DSD function. Providing better instructions for finding firmware upgrades and uploading new firmware would also help, as would an in-depth explanation of phono setup\u2014especially the \u201crename\u201d and \u201cedit the name\u201d sequences. (You can set up the cartridge-optimizer feature for three different cartridges with a front-panel name for each.) Oddly enough, Technics provided me with one of the best explanations of older phono-equalization curves that I\u2019ve ever seen but did not include it in the manual. Note that the Technics offers both unbalanced and balanced phono inputs, if you have a tonearm whose wiring supports a balanced phono connection. Also, the phonostage is a completely discrete design.

It shows how quickly digital sound is evolving and provides an exceptional mix of well-engineered features in a single integrated unit\u2014drawing on much of the technology used in the Technics SU-R1 reference system that Alan Taffel review in the October 2016 issue of TAS. What really counts from an audiophile perspective, however, is that the SU-R1000 provides excellent sonics from both its digital and analog inputs, as well as offering some unique advantages in terms of cartridge equalization and sound quality in its phono front end. The SU-R1000 also has the ability to use digital processing and test tones to improve its interface with a given speaker and listening room. At $9499, the unit is scarcely cheap, but it is still highly competitive at that price, and it offers a uniquely compact package for the electronics that make up a high-end system.I\u2019m giving this integrated the praise its designers and engineers deserve at the start because I\u2019m going to go on to raise a number of issues about the manufacturer\u2019s technical data and instructions\u2014none of which affects its practical operation and sound quality. With proper attention to setup, the SU-R1000 provides a remarkably uncolored sound, and exceptional detail, dynamics, and overall performance. Technics SU-R1000 Integrated Amplifier rearThe SU-R1000 has no clearly audible colorations that affect its frequency response or performance from the lowest levels of amplification to the limits of its 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. If anything, it may be too uncolored for some audiophiles. It has no voicing other than a clear effort to be as neutral as possible. If you use electronics that are voiced to add a touch of euphony to your system, you\u2019ll have to give the SU-R1000\u2019s other virtues priority. As for functionality, about the only practical limit I encountered is that it does not have built-in streaming, although it can handle any PCM signal from 32k to 384k up to 32 bits, and a full range of DSD signals, as well. Its digital sound quality rivals that of some of the best DACs, particularly in terms of life and dynamics, soundstage coherence, and timbral fidelity. It does very well with MQA, although I still prefer using actual high-resolution signals when the music truly has high resolution than reprocessing the source using higher sampling and bit-rates.I should also note that there is another reason I\u2019m placing this praise for the SU-R1000\u2019s sound quality at the start of this review. I realize that a number of American and European high-end audiophiles have a lingering prejudice against Japanese products, particularly from firms like Technics, which make mass-marketed mid-fi as well as high-end gear. So, let me make it clear: This is no ordinary product, and some of its special features truly are special. More than that, whatever your current view may be of \u201cdigital sound,\u201d this unit really is worth auditioning. This is particularly true with a dealer who will actually demonstrate what its phono-cartridge optimization and equalization and its Load Adaptive Phase Calibration (LAPC) amplifier can do to make subtle but very real improvements in interface, speaker optimization, and sound quality.Pages: 1 2 3 4 5 6 7Tags:INTEGRATED AMPLIFIERTECHNICSMost PopularThe Ten Most Significant Amplifiers of All TimeThe Ten Most Significant Amplifiers of All Timeby TAS Staff Apr 01st, 2011top_50_202050 Greatest Bargains in High-End Audioby TAS Staff Dec 14th, 2020rega_p6Rega P6 Turntable, RB330 Tonearm, Neo PSU, and Ania Moving-Coil Cartridgeby Wayne Garcia May 06th, 2021Check out our selections for loudspeakers2021 Editors\u2019 Choice Awards: Loudspeakers $10,000 \u2013 $20,000by TAS Staff Mar 30th, 2021 TopBACK TO TOPBy Anthony CordesmanMore articles from this editorCat IconREAD PREVIOUSThe End of An Era: RIP Rocky Mountain Audio FestTechnics SU-R1000 Integrated AmplifierREAD NEXTTechnics SU-R1000 Integrated AmplifierRead Next From ReviewSEE ALLClearaudio Concept Dark Wood Active TurntableREVIEWClearaudio Concept Dark Wood Active TurntableIt\u2019s easy to think of turntables from only a single [\u2026]by Neil Gader Aug 31st, 2021DS Audio Grand Master Cartridge and Grand Master EqualizerREVIEWDS Audio Grand Master Cartridge and Grand Master EqualizerIt seems like it was only yesterday that I rave-reviewed [\u2026]by Jonathan Valin Aug 25th, 2021My_Sonic_Labs_Signature_Gold_MC_Cartridge_Angle_Left_FrontREVIEWKoetsu Rosewood Signature Platinum & My Sonic Lab Signature Gold Moving-Coil CartridgesAlthough my wife and I are longtime fans of Japanese [\u2026]by Wayne Garcia Aug 24th, 2021Luxman D-10XREVIEWLuxman D-10X CD\/SACD Player and DACSome thirteen years ago I reviewed a pair of Luxman [\u2026]by Paul Seydor Aug 16th, 2021Sign Up To Our NewsletterName*Your NameFirstEmailYour EmailConsent* I have read and agree to the terms and conditions*BrandsThe Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation.Martin Logan Paradigmhttps:\/\/images.theabsolutesound.com\/wp-content\/uploads\/2020\/09\/logo-white.pngThe Absolute Sound is the world\u2019s preeminent source of expert reviews, features, and commentary on high-performance audio and music.SUBSCRIBEMAGAZINEAbout usShopAdvertiseBack IssuesCONNECTFacebookInstagramYoutubeContact via EmailJOIN OUR NEWSLETTEREmailEnter Your Email HereTerms and conditions Privacy Community GuidelinesCopyright \u00a9 2021 The Absolute Sound.

I also realize that most readers are far more interested in descriptions of the sound quality of a given product than in descriptions of its technology. However, the SU-R1000 has so many additional features and new areas of circuit topology that they really are worth exploring. Even if you are only interested in the overall development of digital high-end products, and how they can be used to improve sound quality, you will find reading about Technics\u2019 tech and features interesting enough to visit the manufacturer\u2019s web site. The text printed there does suffer from all of the usual marketing hype\u2014sometimes making the real level of engineering progress unclear\u2014but the SU-R1000 white paper gets many key points across. It also illustrates how meaningless it can be to call a modern switching amplifier \u201cClass D\u201d instead of getting into the design details. The SU-R1000 has a switching output stage, but one that is driven by digital signals. Digital sources are converted to analog in the switching output stage without the need for analog circuits or a traditional DAC. I\u2019d pay particular attention to the description of the JENO (Jitter Elimination and Noise-shaping Optimization) Engine, ADCT (Active Distortion Cancelling Technology), LAPC (Load Adaptive Phase Calibration), Advanced Speed Silent Power Supply, use of four independent power supply units, the battery-driven clock generator, and, especially, the Intelligent Phono EQ. The descriptions are technically vague as to the \u201chow\u201d and full of details about exactly what they do to improve sonics, but the website gets the main points across, and it provides an interesting checklist for comparison with what other competitive integrated amps do\u2014or do not do\u2014in each area.Technics SU-R1000 Integrated Amplifier interiorYou also get a clear idea from the pictures in the Technics literature of how well the SU-R1000 is built, and how clean its \u201cform follows function\u201d design really is. There can\u2019t actually be a Japanese version of \u201cBauhaus\u201d industrial design at Technics, but there are obvious elements of that purist approach, and of the effort to create an appearance that borders on sculpture, in the SU-R1000. I also can\u2019t avoid a personal addiction to the large illuminated VU meters in the front panel that show nominal wattage. It might well have been better to provide an LCD that made the menu easier to use, and the resulting set-up status clearer, but if that had been the case the SU-R1000 wouldn\u2019t have come anywhere near as close to being a work of art.There are also some practical aspects of the SU-R1000 that deserve attention. This is one of the best-engineered products I\u2019ve ever reviewed, but it also has one of the worst instruction manuals. It skims over far too many details\u2014like the character of the tone controls and phono equalization options. But more than that, the remote is designed for command-driven setup and adjustment, as well as ordinary operation. Many of those commands involve fairly complex sequences, which have to be carefully keyed-in using the small screen on the remote\u2019s front panel. I\u2019m a Mac person, not a PC person, and I found the manual to be a bit fuzzy on the proper order of commands, and it took me a day of so to get used to the remote. In fact, I had to experiment at times to figure out what the actual sequence was. This manual for the SU-R1000 is available for download, and there are many areas where Technics could provide a clearer picture of what to do, what actually happens when a given command is followed, and what to listen for. Technics does have some additional information sheets on the web that help with this, but having a couple of pages each that cover LAPC and phono-cartridge optimization in real depth, and that explain each control and feature in real depth, would be better. So would providing in-depth instructions on using other Technics equipment\u2014and that from other manufacturers\u2014for streaming and for using the DSD function. Providing better instructions for finding firmware upgrades and uploading new firmware would also help, as would an in-depth explanation of phono setup\u2014especially the \u201crename\u201d and \u201cedit the name\u201d sequences. (You can set up the cartridge-optimizer feature for three different cartridges with a front-panel name for each.) Oddly enough, Technics provided me with one of the best explanations of older phono-equalization curves that I\u2019ve ever seen but did not include it in the manual. Note that the Technics offers both unbalanced and balanced phono inputs, if you have a tonearm whose wiring supports a balanced phono connection. Also, the phonostage is a completely discrete design.

To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and re-quantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These technologies enable Technics digital amplifier designs to reproduce the natural and delicate nuances of music.ADCT(Active Distortion Cancelling Technology)Circuit Diagram of Digital Amplifier TechnologyThe Active Distortion Cancelling Technology newly developed by Technics accurately extracts and removes distortion in the power output stage which is generated by the speaker\\u2019s counter electromotive force and voltage drops. In the Hi-Fi audio market where an unlimited number of audio systems can be configured by combining various products, high-end audio amplifiers need to optimally drive a diversity of speakers. The Active Distortion Cancelling Technology accurately extracts distortion by determining the difference between the speaker terminal output and JENO output and then applies correction to the output digital signal, thus correcting the conventional digital amp system. This provides powerful speaker driving force and acoustic energy while offering the superior benefits of a digital amplifier, such as low noise, precise sound image and expansive sound ambience, regardless of the types of connected speakers.Advanced Speed Silent Power SupplyGraph of Super High Speed Switching Power Supply Picture of GaN-FET(left) and SiC Diode(right)The SU-R1000 uses a switching power supply system to ensure a stable supply of voltage and current required by the digital amp. In a conventional switching power supply system, the ON time of the switching operation was controlled in order to stabilise the voltage, and this causes the switching frequency to fluctuate according to the load, resulting in a modulation noise to affect the sound quality. The Advanced Speed Silent Power Supply has eliminated this noise by fixing the switching frequency in the 400kHz band. Furthermore, a Super Low Noise Regulator is provided in the later stage. This prevents the decrease of regulation resulting from the fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a high-response power supply that results in the best performance from the digital amplifier.Four Independent Power Supply UnitsPicture of Pre AmplifierIn the SU-R1000, every element comprising the power supply has been diligently studied and revised for higher sound quality. What\\u2019s more, four independent power supply units are provided for different circuit blocks for further enhancement of sound quality. Since the SU-R1000 is an integrated amplifier, the internal circuits consist of a pre-amp stage and power amp stage in a mix of analogue and digital circuits. The Phono-EQ section which processes minute analogue signals is particularly susceptible to the effect of noise transmitted through the power supply line. The SU-R1000 uses separate power supply units for the analogue circuits and digital circuits in the pre-amp stage. It also uses separate power supply units for the right and left channels in the power amp stage that requires large electrical power. With the four independent power supply units, the SU-R1000 prevents power-line-induced interference among the circuit blocks and realises a high S\/N ratio and superb separation.High-grade Digital\/Analog I\/O CircuitPictures of component parts for High-grade Digital\/Analog I\/O CircuitThe phono input section and analogue input section feature a full-discrete circuit design. Technics has realised an ideal, symmetrical circuit layout and performed meticulous tuning. The new circuits prevent interference between the right and left channels and achieve excellent channel separation. Furthermore, the phono input section and XLR input section employ completely balanced transmission to ensure high-purity signal transmission with minimum effect of noise. The USB input circuit in the digital input section is equipped with a capacitor of high-quality ruby mica and a power conditioner with nonmagnetic carbon film resistors for blocking electrical noise e.g. from a PC and for minimising the effect of external noise. The A\/D converter incorporates a high-performance chip made by Asahi Kasei Microdevices (AKM) for high-precision A\/D conversion. Thus, the SU-R1000 reproduces outstanding sound quality from any analogue or digital input sources.High Rigidity Chassis and DesignPicture of High Rigidity Chassis and DesignThe rigidity of the chassis has been enhanced extensively to suppress the enclosure vibration that is also a source of noise. The inner chassis features a double-deck separated structure. Mounted on the upper deck is the power amp section consisting of the amplification circuit and its power supply circuit. Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates. They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels.Input and output terminals made of meticulously selected high-quality parts- Speaker terminals designed to allow connection of extra-large diameter speaker cables- Y-lug terminals for ensuring reliable cable connection- Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC)- Analogue input terminals with gold-plated, machined brass partsTechnics\\u2019 refined design- Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter- Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finishedCrosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridgeGraphic of Crosstalk CancelerThis function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000.

To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and re-quantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These technologies enable Technics digital amplifier designs to reproduce the natural and delicate nuances of music.ADCT(Active Distortion Cancelling Technology)Circuit Diagram of Digital Amplifier TechnologyThe Active Distortion Cancelling Technology newly developed by Technics accurately extracts and removes distortion in the power output stage which is generated by the speaker\u2019s counter electromotive force and voltage drops. In the Hi-Fi audio market where an unlimited number of audio systems can be configured by combining various products, high-end audio amplifiers need to optimally drive a diversity of speakers. The Active Distortion Cancelling Technology accurately extracts distortion by determining the difference between the speaker terminal output and JENO output and then applies correction to the output digital signal, thus correcting the conventional digital amp system. This provides powerful speaker driving force and acoustic energy while offering the superior benefits of a digital amplifier, such as low noise, precise sound image and expansive sound ambience, regardless of the types of connected speakers.Advanced Speed Silent Power SupplyGraph of Super High Speed Switching Power Supply Picture of GaN-FET(left) and SiC Diode(right)The SU-R1000 uses a switching power supply system to ensure a stable supply of voltage and current required by the digital amp. In a conventional switching power supply system, the ON time of the switching operation was controlled in order to stabilise the voltage, and this causes the switching frequency to fluctuate according to the load, resulting in a modulation noise to affect the sound quality. The Advanced Speed Silent Power Supply has eliminated this noise by fixing the switching frequency in the 400kHz band. Furthermore, a Super Low Noise Regulator is provided in the later stage. This prevents the decrease of regulation resulting from the fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a high-response power supply that results in the best performance from the digital amplifier.Four Independent Power Supply UnitsPicture of Pre AmplifierIn the SU-R1000, every element comprising the power supply has been diligently studied and revised for higher sound quality. What\u2019s more, four independent power supply units are provided for different circuit blocks for further enhancement of sound quality. Since the SU-R1000 is an integrated amplifier, the internal circuits consist of a pre-amp stage and power amp stage in a mix of analogue and digital circuits. The Phono-EQ section which processes minute analogue signals is particularly susceptible to the effect of noise transmitted through the power supply line. The SU-R1000 uses separate power supply units for the analogue circuits and digital circuits in the pre-amp stage. It also uses separate power supply units for the right and left channels in the power amp stage that requires large electrical power. With the four independent power supply units, the SU-R1000 prevents power-line-induced interference among the circuit blocks and realises a high S\/N ratio and superb separation.High-grade Digital\/Analog I\/O CircuitPictures of component parts for High-grade Digital\/Analog I\/O CircuitThe phono input section and analogue input section feature a full-discrete circuit design. Technics has realised an ideal, symmetrical circuit layout and performed meticulous tuning. The new circuits prevent interference between the right and left channels and achieve excellent channel separation. Furthermore, the phono input section and XLR input section employ completely balanced transmission to ensure high-purity signal transmission with minimum effect of noise. The USB input circuit in the digital input section is equipped with a capacitor of high-quality ruby mica and a power conditioner with nonmagnetic carbon film resistors for blocking electrical noise e.g. from a PC and for minimising the effect of external noise. The A\/D converter incorporates a high-performance chip made by Asahi Kasei Microdevices (AKM) for high-precision A\/D conversion. Thus, the SU-R1000 reproduces outstanding sound quality from any analogue or digital input sources.High Rigidity Chassis and DesignPicture of High Rigidity Chassis and DesignThe rigidity of the chassis has been enhanced extensively to suppress the enclosure vibration that is also a source of noise. The inner chassis features a double-deck separated structure. Mounted on the upper deck is the power amp section consisting of the amplification circuit and its power supply circuit. Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates. They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels.Input and output terminals made of meticulously selected high-quality parts- Speaker terminals designed to allow connection of extra-large diameter speaker cables- Y-lug terminals for ensuring reliable cable connection- Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC)- Analogue input terminals with gold-plated, machined brass partsTechnics\u2019 refined design- Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter- Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finishedCrosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridgeGraphic of Crosstalk CancelerThis function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000. It then performs reverse-correction using the built-in DSP to achieve significant improvement of the crosstalk characteristic. This results in a more precise sound image and a wider sound ambience.Get InspiredLOAD MORESpecsPhoto of Stereo Integrated Amplifier SU-R1000Colour: Sliver: SU-R1000E-SSliverColour: Black: SU-R1000E-KBlackSize and WeightHeight191mmWidth430mmDepth459mmWeight22.8kg*Approx.JENO Engine (Jitter Elimination and Noiseshaping Optimisation)ADCT (Active Distortion Cancelling Technology)LAPC (Load Adaptive Phase Calibration)Advanced Speed Silent Power SupplyFour Independent Power Supply UnitsIntelligent Phono EQSEE ALL SPECSReviewsUSER REVIEWSPhoto of Stereo Integrated Amplifier SU-R1000Be the first to write a customer review.WRITE A CUSTOMER REVIEWLearn About The CategoryReference ClassGet Supportfor Stereo Integrated Amplifier SU-R1000VISIT THE SUPPORT PAGEProductsReference ClassSU-R1000PrintBack to topArea \/ CountryCopyright \u00a9 2021 Panasonic UK & IrelandAbout Us Terms of Use Privacy Policy Cookie Policy Contact Us Where to BuyFacebookTwitterYouTubeInstagram Logo ReviewsReviews News Shows Blog Buyer\u2019s Guides Magazine Music Brands SUBSCRIBEhttps:\/\/www.theabsolutesound.com\/articles\/technics-su-r1000-integrated-amplifier Technics SU-R1000 Integrated AmplifierREVIEW by Anthony Cordesman Sep 03rd, 2021A A ATechnics SU-R1000 Integrated AmplifierLet me begin this review with my conclusion: The new Technics SU-R1000 integrated amplifier is one of the most innovative and best-sounding pieces of electronics I\u2019ve had the opportunity to audition in recent years. It shows how quickly digital sound is evolving and provides an exceptional mix of well-engineered features in a single integrated unit\u2014drawing on much of the technology used in the Technics SU-R1 reference system that Alan Taffel review in the October 2016 issue of TAS. What really counts from an audiophile perspective, however, is that the SU-R1000 provides excellent sonics from both its digital and analog inputs, as well as offering some unique advantages in terms of cartridge equalization and sound quality in its phono front end. The SU-R1000 also has the ability to use digital processing and test tones to improve its interface with a given speaker and listening room. At $9499, the unit is scarcely cheap, but it is still highly competitive at that price, and it offers a uniquely compact package for the electronics that make up a high-end system.I\u2019m giving this integrated the praise its designers and engineers deserve at the start because I\u2019m going to go on to raise a number of issues about the manufacturer\u2019s technical data and instructions\u2014none of which affects its practical operation and sound quality. With proper attention to setup, the SU-R1000 provides a remarkably uncolored sound, and exceptional detail, dynamics, and overall performance. Technics SU-R1000 Integrated Amplifier rearThe SU-R1000 has no clearly audible colorations that affect its frequency response or performance from the lowest levels of amplification to the limits of its 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. If anything, it may be too uncolored for some audiophiles. It has no voicing other than a clear effort to be as neutral as possible. If you use electronics that are voiced to add a touch of euphony to your system, you\u2019ll have to give the SU-R1000\u2019s other virtues priority. As for functionality, about the only practical limit I encountered is that it does not have built-in streaming, although it can handle any PCM signal from 32k to 384k up to 32 bits, and a full range of DSD signals, as well. Its digital sound quality rivals that of some of the best DACs, particularly in terms of life and dynamics, soundstage coherence, and timbral fidelity. It does very well with MQA, although I still prefer using actual high-resolution signals when the music truly has high resolution than reprocessing the source using higher sampling and bit-rates.I should also note that there is another reason I\u2019m placing this praise for the SU-R1000\u2019s sound quality at the start of this review. I realize that a number of American and European high-end audiophiles have a lingering prejudice against Japanese products, particularly from firms like Technics, which make mass-marketed mid-fi as well as high-end gear. So, let me make it clear: This is no ordinary product, and some of its special features truly are special. More than that, whatever your current view may be of \u201cdigital sound,\u201d this unit really is worth auditioning. This is particularly true with a dealer who will actually demonstrate what its phono-cartridge optimization and equalization and its Load Adaptive Phase Calibration (LAPC) amplifier can do to make subtle but very real improvements in interface, speaker optimization, and sound quality.Pages: 1 2 3 4 5 6 7Tags:INTEGRATED AMPLIFIERTECHNICSMost PopularThe Ten Most Significant Amplifiers of All TimeThe Ten Most Significant Amplifiers of All Timeby TAS Staff Apr 01st, 2011top_50_202050 Greatest Bargains in High-End Audioby TAS Staff Dec 14th, 2020rega_p6Rega P6 Turntable, RB330 Tonearm, Neo PSU, and Ania Moving-Coil Cartridgeby Wayne Garcia May 06th, 2021Check out our selections for loudspeakers2021 Editors\u2019 Choice Awards: Loudspeakers $10,000 \u2013 $20,000by TAS Staff Mar 30th, 2021 TopBACK TO TOPBy Anthony CordesmanMore articles from this editorCat IconREAD PREVIOUSThe End of An Era: RIP Rocky Mountain Audio FestTechnics SU-R1000 Integrated AmplifierREAD NEXTTechnics SU-R1000 Integrated AmplifierRead Next From ReviewSEE ALLClearaudio Concept Dark Wood Active TurntableREVIEWClearaudio Concept Dark Wood Active TurntableIt\u2019s easy to think of turntables from only a single [\u2026]by Neil Gader Aug 31st, 2021DS Audio Grand Master Cartridge and Grand Master EqualizerREVIEWDS Audio Grand Master Cartridge and Grand Master EqualizerIt seems like it was only yesterday that I rave-reviewed [\u2026]by Jonathan Valin Aug 25th, 2021My_Sonic_Labs_Signature_Gold_MC_Cartridge_Angle_Left_FrontREVIEWKoetsu Rosewood Signature Platinum & My Sonic Lab Signature Gold Moving-Coil CartridgesAlthough my wife and I are longtime fans of Japanese [\u2026]by Wayne Garcia Aug 24th, 2021Luxman D-10XREVIEWLuxman D-10X CD\/SACD Player and DACSome thirteen years ago I reviewed a pair of Luxman [\u2026]by Paul Seydor Aug 16th, 2021Sign Up To Our NewsletterName*Your NameFirstEmailYour EmailConsent* I have read and agree to the terms and conditions*BrandsThe Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation.Martin Logan Paradigmhttps:\/\/images.theabsolutesound.com\/wp-content\/uploads\/2020\/09\/logo-white.pngThe Absolute Sound is the world\u2019s preeminent source of expert reviews, features, and commentary on high-performance audio and music.SUBSCRIBEMAGAZINEAbout usShopAdvertiseBack IssuesCONNECTFacebookInstagramYoutubeContact via EmailJOIN OUR NEWSLETTEREmailEnter Your Email HereTerms and conditions Privacy Community GuidelinesCopyright \u00a9 2021 The Absolute Sound.

To eliminate the degradation of sound caused by jitter, Technics has developed an original jitter reduction circuit, comprising a clock generator in the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter for suppressing jitter in the high-frequency range. Thus it reduces jitter in an ideal way over the entire frequency range. This works with original high-precision PWM (Pulse Width Modulation) conversion circuit, optimising the noise-shaping speed, the degree and re-quantisation number, and the PWM gradation, in order to convert high-resolution signals to PWM without causing any damage to the dynamic range. These technologies enable Technics digital amplifier designs to reproduce the natural and delicate nuances of music.ADCT(Active Distortion Cancelling Technology)Circuit Diagram of Digital Amplifier TechnologyThe Active Distortion Cancelling Technology newly developed by Technics accurately extracts and removes distortion in the power output stage which is generated by the speaker\u2019s counter electromotive force and voltage drops. In the Hi-Fi audio market where an unlimited number of audio systems can be configured by combining various products, high-end audio amplifiers need to optimally drive a diversity of speakers. The Active Distortion Cancelling Technology accurately extracts distortion by determining the difference between the speaker terminal output and JENO output and then applies correction to the output digital signal, thus correcting the conventional digital amp system. This provides powerful speaker driving force and acoustic energy while offering the superior benefits of a digital amplifier, such as low noise, precise sound image and expansive sound ambience, regardless of the types of connected speakers.Advanced Speed Silent Power SupplyGraph of Super High Speed Switching Power Supply Picture of GaN-FET(left) and SiC Diode(right)The SU-R1000 uses a switching power supply system to ensure a stable supply of voltage and current required by the digital amp. In a conventional switching power supply system, the ON time of the switching operation was controlled in order to stabilise the voltage, and this causes the switching frequency to fluctuate according to the load, resulting in a modulation noise to affect the sound quality. The Advanced Speed Silent Power Supply has eliminated this noise by fixing the switching frequency in the 400kHz band. Furthermore, a Super Low Noise Regulator is provided in the later stage. This prevents the decrease of regulation resulting from the fixed switching frequency and impedes the mixing of noise component into high frequencies. The result is a high-response power supply that results in the best performance from the digital amplifier.Four Independent Power Supply UnitsPicture of Pre AmplifierIn the SU-R1000, every element comprising the power supply has been diligently studied and revised for higher sound quality. What\u2019s more, four independent power supply units are provided for different circuit blocks for further enhancement of sound quality. Since the SU-R1000 is an integrated amplifier, the internal circuits consist of a pre-amp stage and power amp stage in a mix of analogue and digital circuits. The Phono-EQ section which processes minute analogue signals is particularly susceptible to the effect of noise transmitted through the power supply line. The SU-R1000 uses separate power supply units for the analogue circuits and digital circuits in the pre-amp stage. It also uses separate power supply units for the right and left channels in the power amp stage that requires large electrical power. With the four independent power supply units, the SU-R1000 prevents power-line-induced interference among the circuit blocks and realises a high S\/N ratio and superb separation.High-grade Digital\/Analog I\/O CircuitPictures of component parts for High-grade Digital\/Analog I\/O CircuitThe phono input section and analogue input section feature a full-discrete circuit design. Technics has realised an ideal, symmetrical circuit layout and performed meticulous tuning. The new circuits prevent interference between the right and left channels and achieve excellent channel separation. Furthermore, the phono input section and XLR input section employ completely balanced transmission to ensure high-purity signal transmission with minimum effect of noise. The USB input circuit in the digital input section is equipped with a capacitor of high-quality ruby mica and a power conditioner with nonmagnetic carbon film resistors for blocking electrical noise e.g. from a PC and for minimising the effect of external noise. The A\/D converter incorporates a high-performance chip made by Asahi Kasei Microdevices (AKM) for high-precision A\/D conversion. Thus, the SU-R1000 reproduces outstanding sound quality from any analogue or digital input sources.High Rigidity Chassis and DesignPicture of High Rigidity Chassis and DesignThe rigidity of the chassis has been enhanced extensively to suppress the enclosure vibration that is also a source of noise. The inner chassis features a double-deck separated structure. Mounted on the upper deck is the power amp section consisting of the amplification circuit and its power supply circuit. Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates. They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels.Input and output terminals made of meticulously selected high-quality parts- Speaker terminals designed to allow connection of extra-large diameter speaker cables- Y-lug terminals for ensuring reliable cable connection- Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC)- Analogue input terminals with gold-plated, machined brass partsTechnics\u2019 refined design- Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter- Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finishedCrosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridgeGraphic of Crosstalk CancelerThis function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000. It then performs reverse-correction using the built-in DSP to achieve significant improvement of the crosstalk characteristic. This results in a more precise sound image and a wider sound ambience.Get InspiredLOAD MORESpecsPhoto of Stereo Integrated Amplifier SU-R1000Colour: Sliver: SU-R1000E-SSliverColour: Black: SU-R1000E-KBlackSize and WeightHeight191mmWidth430mmDepth459mmWeight22.8kg*Approx.JENO Engine (Jitter Elimination and Noiseshaping Optimisation)ADCT (Active Distortion Cancelling Technology)LAPC (Load Adaptive Phase Calibration)Advanced Speed Silent Power SupplyFour Independent Power Supply UnitsIntelligent Phono EQSEE ALL SPECSReviewsUSER REVIEWSPhoto of Stereo Integrated Amplifier SU-R1000Be the first to write a customer review.WRITE A CUSTOMER REVIEWLearn About The CategoryReference ClassGet Supportfor Stereo Integrated Amplifier SU-R1000VISIT THE SUPPORT PAGEProductsReference ClassSU-R1000PrintBack to topArea \/ CountryCopyright \u00a9 2021 Panasonic UK & IrelandAbout Us Terms of Use Privacy Policy Cookie Policy Contact Us Where to BuyFacebookTwitterYouTubeInstagram Logo ReviewsReviews News Shows Blog Buyer\u2019s Guides Magazine Music Brands SUBSCRIBEhttps:\/\/www.theabsolutesound.com\/articles\/technics-su-r1000-integrated-amplifier Technics SU-R1000 Integrated AmplifierREVIEW by Anthony Cordesman Sep 03rd, 2021A A ATechnics SU-R1000 Integrated AmplifierLet me begin this review with my conclusion: The new Technics SU-R1000 integrated amplifier is one of the most innovative and best-sounding pieces of electronics I\u2019ve had the opportunity to audition in recent years. It shows how quickly digital sound is evolving and provides an exceptional mix of well-engineered features in a single integrated unit\u2014drawing on much of the technology used in the Technics SU-R1 reference system that Alan Taffel review in the October 2016 issue of TAS. What really counts from an audiophile perspective, however, is that the SU-R1000 provides excellent sonics from both its digital and analog inputs, as well as offering some unique advantages in terms of cartridge equalization and sound quality in its phono front end. The SU-R1000 also has the ability to use digital processing and test tones to improve its interface with a given speaker and listening room. At $9499, the unit is scarcely cheap, but it is still highly competitive at that price, and it offers a uniquely compact package for the electronics that make up a high-end system.I\u2019m giving this integrated the praise its designers and engineers deserve at the start because I\u2019m going to go on to raise a number of issues about the manufacturer\u2019s technical data and instructions\u2014none of which affects its practical operation and sound quality. With proper attention to setup, the SU-R1000 provides a remarkably uncolored sound, and exceptional detail, dynamics, and overall performance. Technics SU-R1000 Integrated Amplifier rearThe SU-R1000 has no clearly audible colorations that affect its frequency response or performance from the lowest levels of amplification to the limits of its 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. If anything, it may be too uncolored for some audiophiles. It has no voicing other than a clear effort to be as neutral as possible. If you use electronics that are voiced to add a touch of euphony to your system, you\u2019ll have to give the SU-R1000\u2019s other virtues priority. As for functionality, about the only practical limit I encountered is that it does not have built-in streaming, although it can handle any PCM signal from 32k to 384k up to 32 bits, and a full range of DSD signals, as well. Its digital sound quality rivals that of some of the best DACs, particularly in terms of life and dynamics, soundstage coherence, and timbral fidelity. It does very well with MQA, although I still prefer using actual high-resolution signals when the music truly has high resolution than reprocessing the source using higher sampling and bit-rates.I should also note that there is another reason I\u2019m placing this praise for the SU-R1000\u2019s sound quality at the start of this review. I realize that a number of American and European high-end audiophiles have a lingering prejudice against Japanese products, particularly from firms like Technics, which make mass-marketed mid-fi as well as high-end gear. So, let me make it clear: This is no ordinary product, and some of its special features truly are special. More than that, whatever your current view may be of \u201cdigital sound,\u201d this unit really is worth auditioning. This is particularly true with a dealer who will actually demonstrate what its phono-cartridge optimization and equalization and its Load Adaptive Phase Calibration (LAPC) amplifier can do to make subtle but very real improvements in interface, speaker optimization, and sound quality.Pages: 1 2 3 4 5 6 7Tags:INTEGRATED AMPLIFIERTECHNICSMost PopularThe Ten Most Significant Amplifiers of All TimeThe Ten Most Significant Amplifiers of All Timeby TAS Staff Apr 01st, 2011top_50_202050 Greatest Bargains in High-End Audioby TAS Staff Dec 14th, 2020rega_p6Rega P6 Turntable, RB330 Tonearm, Neo PSU, and Ania Moving-Coil Cartridgeby Wayne Garcia May 06th, 2021Check out our selections for loudspeakers2021 Editors\u2019 Choice Awards: Loudspeakers $10,000 \u2013 $20,000by TAS Staff Mar 30th, 2021 TopBACK TO TOPBy Anthony CordesmanMore articles from this editorCat IconREAD PREVIOUSThe End of An Era: RIP Rocky Mountain Audio FestTechnics SU-R1000 Integrated AmplifierREAD NEXTTechnics SU-R1000 Integrated AmplifierRead Next From ReviewSEE ALLClearaudio Concept Dark Wood Active TurntableREVIEWClearaudio Concept Dark Wood Active TurntableIt\u2019s easy to think of turntables from only a single [\u2026]by Neil Gader Aug 31st, 2021DS Audio Grand Master Cartridge and Grand Master EqualizerREVIEWDS Audio Grand Master Cartridge and Grand Master EqualizerIt seems like it was only yesterday that I rave-reviewed [\u2026]by Jonathan Valin Aug 25th, 2021My_Sonic_Labs_Signature_Gold_MC_Cartridge_Angle_Left_FrontREVIEWKoetsu Rosewood Signature Platinum & My Sonic Lab Signature Gold Moving-Coil CartridgesAlthough my wife and I are longtime fans of Japanese [\u2026]by Wayne Garcia Aug 24th, 2021Luxman D-10XREVIEWLuxman D-10X CD\/SACD Player and DACSome thirteen years ago I reviewed a pair of Luxman [\u2026]by Paul Seydor Aug 16th, 2021Sign Up To Our NewsletterName*Your NameFirstEmailYour EmailConsent* I have read and agree to the terms and conditions*BrandsThe Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation.Martin Logan Paradigmhttps:\/\/images.theabsolutesound.com\/wp-content\/uploads\/2020\/09\/logo-white.pngThe Absolute Sound is the world\u2019s preeminent source of expert reviews, features, and commentary on high-performance audio and music.SUBSCRIBEMAGAZINEAbout usShopAdvertiseBack IssuesCONNECTFacebookInstagramYoutubeContact via EmailJOIN OUR NEWSLETTEREmailEnter Your Email HereTerms and conditions Privacy Community GuidelinesCopyright \u00a9 2021 The Absolute Sound.

I also realize that most readers are far more interested in descriptions of the sound quality of a given product than in descriptions of its technology. However, the SU-R1000 has so many additional features and new areas of circuit topology that they really are worth exploring. Even if you are only interested in the overall development of digital high-end products, and how they can be used to improve sound quality, you will find reading about Technics\u2019 tech and features interesting enough to visit the manufacturer\u2019s web site. The text printed there does suffer from all of the usual marketing hype\u2014sometimes making the real level of engineering progress unclear\u2014but the SU-R1000 white paper gets many key points across. It also illustrates how meaningless it can be to call a modern switching amplifier \u201cClass D\u201d instead of getting into the design details. The SU-R1000 has a switching output stage, but one that is driven by digital signals. Digital sources are converted to analog in the switching output stage without the need for analog circuits or a traditional DAC. I\u2019d pay particular attention to the description of the JENO (Jitter Elimination and Noise-shaping Optimization) Engine, ADCT (Active Distortion Cancelling Technology), LAPC (Load Adaptive Phase Calibration), Advanced Speed Silent Power Supply, use of four independent power supply units, the battery-driven clock generator, and, especially, the Intelligent Phono EQ. The descriptions are technically vague as to the \u201chow\u201d and full of details about exactly what they do to improve sonics, but the website gets the main points across, and it provides an interesting checklist for comparison with what other competitive integrated amps do\u2014or do not do\u2014in each area.Technics SU-R1000 Integrated Amplifier interiorYou also get a clear idea from the pictures in the Technics literature of how well the SU-R1000 is built, and how clean its \u201cform follows function\u201d design really is. There can\u2019t actually be a Japanese version of \u201cBauhaus\u201d industrial design at Technics, but there are obvious elements of that purist approach, and of the effort to create an appearance that borders on sculpture, in the SU-R1000. I also can\u2019t avoid a personal addiction to the large illuminated VU meters in the front panel that show nominal wattage. It might well have been better to provide an LCD that made the menu easier to use, and the resulting set-up status clearer, but if that had been the case the SU-R1000 wouldn\u2019t have come anywhere near as close to being a work of art.There are also some practical aspects of the SU-R1000 that deserve attention. This is one of the best-engineered products I\u2019ve ever reviewed, but it also has one of the worst instruction manuals. It skims over far too many details\u2014like the character of the tone controls and phono equalization options. But more than that, the remote is designed for command-driven setup and adjustment, as well as ordinary operation. Many of those commands involve fairly complex sequences, which have to be carefully keyed-in using the small screen on the remote\u2019s front panel. I\u2019m a Mac person, not a PC person, and I found the manual to be a bit fuzzy on the proper order of commands, and it took me a day of so to get used to the remote. In fact, I had to experiment at times to figure out what the actual sequence was. This manual for the SU-R1000 is available for download, and there are many areas where Technics could provide a clearer picture of what to do, what actually happens when a given command is followed, and what to listen for. Technics does have some additional information sheets on the web that help with this, but having a couple of pages each that cover LAPC and phono-cartridge optimization in real depth, and that explain each control and feature in real depth, would be better. So would providing in-depth instructions on using other Technics equipment\u2014and that from other manufacturers\u2014for streaming and for using the DSD function. Providing better instructions for finding firmware upgrades and uploading new firmware would also help, as would an in-depth explanation of phono setup\u2014especially the \u201crename\u201d and \u201cedit the name\u201d sequences. (You can set up the cartridge-optimizer feature for three different cartridges with a front-panel name for each.) Oddly enough, Technics provided me with one of the best explanations of older phono-equalization curves that I\u2019ve ever seen but did not include it in the manual. Note that the Technics offers both unbalanced and balanced phono inputs, if you have a tonearm whose wiring supports a balanced phono connection. Also, the phonostage is a completely discrete design.

Installed on the lower deck is the pre-amp section which is comprised of the analogue input section, including the phono equaliser, and the digital input section as well as the power supply circuits for those circuits. Not only the upper and lower decks but also individual circuit blocks are separated from one another by steel shield plates. These steel shield plates also serve as reinforcing plates for strengthening the rigidity of the entire chassis. On the outside, the front panel is 10-mm thick, while the side panels and top panel are made of 6-mm-thick alumite-treated aluminum plates. They have also improved the rigidity and vibration resistance. The insulators that support the chassis are made of cast iron with excellent signal attenuation characteristics. All in all, the above parts and materials enhance the quality of internal signals and eliminate the effects of external vibrations at highest levels.Input and output terminals made of meticulously selected high-quality parts- Speaker terminals designed to allow connection of extra-large diameter speaker cables- Y-lug terminals for ensuring reliable cable connection- Neutrik-manufactured analogue balance input terminals and PHONO XLR input terminals (exclusively for MC)- Analogue input terminals with gold-plated, machined brass partsTechnics\u2019 refined design- Attractive front panel embellished with high-quality hairline surface finish and equipped with an iconic, large dual-needle meter- Volume dial and selector knob made of parts machined from solid aluminum blocks and spin-finishedCrosstalk Canceller - For measurement and improvement of crosstalk characteristic unique to each cartridgeGraphic of Crosstalk CancelerThis function measures the crosstalk characteristic of the installed cartridge by using the crosstalk measuring signal recorded on the Calibration Record bundled with the SU-R1000. It then performs reverse-correction using the built-in DSP to achieve significant improvement of the crosstalk characteristic. This results in a more precise sound image and a wider sound ambience.Get InspiredLOAD MORESpecsPhoto of Stereo Integrated Amplifier SU-R1000Colour: Sliver: SU-R1000E-SSliverColour: Black: SU-R1000E-KBlackSize and WeightHeight191mmWidth430mmDepth459mmWeight22.8kg*Approx.JENO Engine (Jitter Elimination and Noiseshaping Optimisation)ADCT (Active Distortion Cancelling Technology)LAPC (Load Adaptive Phase Calibration)Advanced Speed Silent Power SupplyFour Independent Power Supply UnitsIntelligent Phono EQSEE ALL SPECSReviewsUSER REVIEWSPhoto of Stereo Integrated Amplifier SU-R1000Be the first to write a customer review.WRITE A CUSTOMER REVIEWLearn About The CategoryReference ClassGet Supportfor Stereo Integrated Amplifier SU-R1000VISIT THE SUPPORT PAGEProductsReference ClassSU-R1000PrintBack to topArea \/ CountryCopyright \u00a9 2021 Panasonic UK & IrelandAbout Us Terms of Use Privacy Policy Cookie Policy Contact Us Where to BuyFacebookTwitterYouTubeInstagram Logo ReviewsReviews News Shows Blog Buyer\u2019s Guides Magazine Music Brands SUBSCRIBEhttps:\/\/www.theabsolutesound.com\/articles\/technics-su-r1000-integrated-amplifier Technics SU-R1000 Integrated AmplifierREVIEW by Anthony Cordesman Sep 03rd, 2021A A ATechnics SU-R1000 Integrated AmplifierLet me begin this review with my conclusion: The new Technics SU-R1000 integrated amplifier is one of the most innovative and best-sounding pieces of electronics I\u2019ve had the opportunity to audition in recent years. It shows how quickly digital sound is evolving and provides an exceptional mix of well-engineered features in a single integrated unit\u2014drawing on much of the technology used in the Technics SU-R1 reference system that Alan Taffel review in the October 2016 issue of TAS. What really counts from an audiophile perspective, however, is that the SU-R1000 provides excellent sonics from both its digital and analog inputs, as well as offering some unique advantages in terms of cartridge equalization and sound quality in its phono front end. The SU-R1000 also has the ability to use digital processing and test tones to improve its interface with a given speaker and listening room. At $9499, the unit is scarcely cheap, but it is still highly competitive at that price, and it offers a uniquely compact package for the electronics that make up a high-end system.I\u2019m giving this integrated the praise its designers and engineers deserve at the start because I\u2019m going to go on to raise a number of issues about the manufacturer\u2019s technical data and instructions\u2014none of which affects its practical operation and sound quality. With proper attention to setup, the SU-R1000 provides a remarkably uncolored sound, and exceptional detail, dynamics, and overall performance. Technics SU-R1000 Integrated Amplifier rearThe SU-R1000 has no clearly audible colorations that affect its frequency response or performance from the lowest levels of amplification to the limits of its 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. If anything, it may be too uncolored for some audiophiles. It has no voicing other than a clear effort to be as neutral as possible. If you use electronics that are voiced to add a touch of euphony to your system, you\u2019ll have to give the SU-R1000\u2019s other virtues priority. As for functionality, about the only practical limit I encountered is that it does not have built-in streaming, although it can handle any PCM signal from 32k to 384k up to 32 bits, and a full range of DSD signals, as well. Its digital sound quality rivals that of some of the best DACs, particularly in terms of life and dynamics, soundstage coherence, and timbral fidelity. It does very well with MQA, although I still prefer using actual high-resolution signals when the music truly has high resolution than reprocessing the source using higher sampling and bit-rates.I should also note that there is another reason I\u2019m placing this praise for the SU-R1000\u2019s sound quality at the start of this review. I realize that a number of American and European high-end audiophiles have a lingering prejudice against Japanese products, particularly from firms like Technics, which make mass-marketed mid-fi as well as high-end gear. So, let me make it clear: This is no ordinary product, and some of its special features truly are special. More than that, whatever your current view may be of \u201cdigital sound,\u201d this unit really is worth auditioning. This is particularly true with a dealer who will actually demonstrate what its phono-cartridge optimization and equalization and its Load Adaptive Phase Calibration (LAPC) amplifier can do to make subtle but very real improvements in interface, speaker optimization, and sound quality.Pages: 1 2 3 4 5 6 7Tags:INTEGRATED AMPLIFIERTECHNICSMost PopularThe Ten Most Significant Amplifiers of All TimeThe Ten Most Significant Amplifiers of All Timeby TAS Staff Apr 01st, 2011top_50_202050 Greatest Bargains in High-End Audioby TAS Staff Dec 14th, 2020rega_p6Rega P6 Turntable, RB330 Tonearm, Neo PSU, and Ania Moving-Coil Cartridgeby Wayne Garcia May 06th, 2021Check out our selections for loudspeakers2021 Editors\u2019 Choice Awards: Loudspeakers $10,000 \u2013 $20,000by TAS Staff Mar 30th, 2021 TopBACK TO TOPBy Anthony CordesmanMore articles from this editorCat IconREAD PREVIOUSThe End of An Era: RIP Rocky Mountain Audio FestTechnics SU-R1000 Integrated AmplifierREAD NEXTTechnics SU-R1000 Integrated AmplifierRead Next From ReviewSEE ALLClearaudio Concept Dark Wood Active TurntableREVIEWClearaudio Concept Dark Wood Active TurntableIt\u2019s easy to think of turntables from only a single [\u2026]by Neil Gader Aug 31st, 2021DS Audio Grand Master Cartridge and Grand Master EqualizerREVIEWDS Audio Grand Master Cartridge and Grand Master EqualizerIt seems like it was only yesterday that I rave-reviewed [\u2026]by Jonathan Valin Aug 25th, 2021My_Sonic_Labs_Signature_Gold_MC_Cartridge_Angle_Left_FrontREVIEWKoetsu Rosewood Signature Platinum & My Sonic Lab Signature Gold Moving-Coil CartridgesAlthough my wife and I are longtime fans of Japanese [\u2026]by Wayne Garcia Aug 24th, 2021Luxman D-10XREVIEWLuxman D-10X CD\/SACD Player and DACSome thirteen years ago I reviewed a pair of Luxman [\u2026]by Paul Seydor Aug 16th, 2021Sign Up To Our NewsletterName*Your NameFirstEmailYour EmailConsent* I have read and agree to the terms and conditions*BrandsThe Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation.Martin Logan Paradigmhttps:\/\/images.theabsolutesound.com\/wp-content\/uploads\/2020\/09\/logo-white.pngThe Absolute Sound is the world\u2019s preeminent source of expert reviews, features, and commentary on high-performance audio and music.SUBSCRIBEMAGAZINEAbout usShopAdvertiseBack IssuesCONNECTFacebookInstagramYoutubeContact via EmailJOIN OUR NEWSLETTEREmailEnter Your Email HereTerms and conditions Privacy Community GuidelinesCopyright \u00a9 2021 The Absolute Sound.

I also realize that most readers are far more interested in descriptions of the sound quality of a given product than in descriptions of its technology. However, the SU-R1000 has so many additional features and new areas of circuit topology that they really are worth exploring. Even if you are only interested in the overall development of digital high-end products, and how they can be used to improve sound quality, you will find reading about Technics\u2019 tech and features interesting enough to visit the manufacturer\u2019s web site. The text printed there does suffer from all of the usual marketing hype\u2014sometimes making the real level of engineering progress unclear\u2014but the SU-R1000 white paper gets many key points across. It also illustrates how meaningless it can be to call a modern switching amplifier \u201cClass D\u201d instead of getting into the design details. The SU-R1000 has a switching output stage, but one that is driven by digital signals. Digital sources are converted to analog in the switching output stage without the need for analog circuits or a traditional DAC. I\u2019d pay particular attention to the description of the JENO (Jitter Elimination and Noise-shaping Optimization) Engine, ADCT (Active Distortion Cancelling Technology), LAPC (Load Adaptive Phase Calibration), Advanced Speed Silent Power Supply, use of four independent power supply units, the battery-driven clock generator, and, especially, the Intelligent Phono EQ. The descriptions are technically vague as to the \u201chow\u201d and full of details about exactly what they do to improve sonics, but the website gets the main points across, and it provides an interesting checklist for comparison with what other competitive integrated amps do\u2014or do not do\u2014in each area.Technics SU-R1000 Integrated Amplifier interiorYou also get a clear idea from the pictures in the Technics literature of how well the SU-R1000 is built, and how clean its \u201cform follows function\u201d design really is. There can\u2019t actually be a Japanese version of \u201cBauhaus\u201d industrial design at Technics, but there are obvious elements of that purist approach, and of the effort to create an appearance that borders on sculpture, in the SU-R1000. I also can\u2019t avoid a personal addiction to the large illuminated VU meters in the front panel that show nominal wattage. It might well have been better to provide an LCD that made the menu easier to use, and the resulting set-up status clearer, but if that had been the case the SU-R1000 wouldn\u2019t have come anywhere near as close to being a work of art.There are also some practical aspects of the SU-R1000 that deserve attention. This is one of the best-engineered products I\u2019ve ever reviewed, but it also has one of the worst instruction manuals. It skims over far too many details\u2014like the character of the tone controls and phono equalization options. But more than that, the remote is designed for command-driven setup and adjustment, as well as ordinary operation. Many of those commands involve fairly complex sequences, which have to be carefully keyed-in using the small screen on the remote\u2019s front panel. I\u2019m a Mac person, not a PC person, and I found the manual to be a bit fuzzy on the proper order of commands, and it took me a day of so to get used to the remote. In fact, I had to experiment at times to figure out what the actual sequence was. This manual for the SU-R1000 is available for download, and there are many areas where Technics could provide a clearer picture of what to do, what actually happens when a given command is followed, and what to listen for. Technics does have some additional information sheets on the web that help with this, but having a couple of pages each that cover LAPC and phono-cartridge optimization in real depth, and that explain each control and feature in real depth, would be better. So would providing in-depth instructions on using other Technics equipment\u2014and that from other manufacturers\u2014for streaming and for using the DSD function. Providing better instructions for finding firmware upgrades and uploading new firmware would also help, as would an in-depth explanation of phono setup\u2014especially the \u201crename\u201d and \u201cedit the name\u201d sequences. (You can set up the cartridge-optimizer feature for three different cartridges with a front-panel name for each.) Oddly enough, Technics provided me with one of the best explanations of older phono-equalization curves that I\u2019ve ever seen but did not include it in the manual. Note that the Technics offers both unbalanced and balanced phono inputs, if you have a tonearm whose wiring supports a balanced phono connection. Also, the phonostage is a completely discrete design.
