ATC SIA2-100 Stereo Integrated Amplifier

Overview

Compact in size yet offering high power output and exceptional resolution, this integrated amplifier with on-board DAC is ideally suited to driving ATC’s small and mid-size passive loudspeakers and a very wide range of loudspeakers from other manufacturers. Understated styling makes it easy to integrate with partnering equipment whilst its small footprint occupies very little space in the home. An ideal partner for our CD2 CD Player.
