NUPRIME AMG STA Power Amplifier and AMG PRA Preamplifier > TAS review

The company was founded back in 2014 by Jason Lim, the former CEO of NuForce, and it specializes in boutique Class D amps, media streamers, and many other products. I was very excited to get a nearly complete system of its AMG STA power amplifier and AMG PRA preamp. The amp and preamp combination have the same form factor and were clearly designed to work in tandem. While I’m a fan of mixing and matching equipment from a wide range of manufacturers, there’s something special about listening to the products from a single line, and getting a sense of  how they work in tandem.

Sticking with the dual-mono setup and the L600s, I put on the Tone Poets vinyl reissue of My Point of View by Herbie Hancock. The tune “King Cobra” opens the B-side, and it features Tony Williams at only 17 years old showing off all his incredible potential, with dancing cymbals that really sparkled through the STA/PRA combo. Williams’ fills sounded exuberant and rhythmically complex, and the system never compromised or slowed down his fascinating drumming. In the midrange, the piano and horns were smooth and silky with a hint of nice, heavy warmth down in their lower regions. Hancock’s solo was quick and slithering, like the song’s namesake, and each note was clearly delineated. Attacks and decays were on point, which added to the whole rhythmic picture building throughout the song. When the horns massed for the theme, each instrument remained wholly itself and focused, creating a wide sense of soundstage. The STA/PRA dual-mono combo worked very well with the L600s, since the speakers have a very solid and deep lower end, and the amp/preamp shines in the lower registers. It was that deep heft that really brought a difficult song like “King Cobra” to life, and leant the entire ensemble a massive sound.
