It’s designed to transmit either 80W across 2 channels at 8-ohms, or 160 watts across 2 channels at 4 ohms. More importantly, it uses ultra-high-current MOS, single push-pull circuitry to ensure top-notch audio reproduction with accurately rendered details. Plus, as an upgrade from previous generations, the PMA-A100 uses an upgraded speaker terminal with cast iron footing for reduced vibration and, again, higher sound quality. Also included are 7 RCA inputs and 3 RCA outputs.
