ATC SIA2-100 > Audiograde Review

All that you want

Inputs wise this amp is very well and sensibly served, making sure all bases are covered for most music fans. The rear panel offers two sets of line-level (RCA) analogue inputs alongside optical (TOSLINK), coaxial (S/PDIF) and USB (Type B) digital sockets. The latter three are handled via an AKM 32-bit DAC chip, with the USB input catering for PCM signals up to 384kHz and native DSD256 for PC and DSD128 for Mac. The amp’s front panel also sports a 3.5mm auxiliary socket for hooking up analogue inputs in a hurry and a 6.35mm headphone jack to keep partners and neighbours happy.

In summary

Despite its modest appearance, this really is a lot of amp for the money. It’s clear ATC has engineered the SIA2-100 to strike a difficult balance of accuracy and neutrality without compromising in the musicality stakes. Put simply it’s an underrated mid to hi-end bargain.
