XDA-3 Differential Reference DAC / Preamp

The XDA-3 is a high-performance two-channel audiophile DAC with a variety of digital inputs, including a very high-performance USB input, an HDMI-ARC input, and two stereo analog inputs. The XDA-3 features a fully balanced, fully differential analog signal path, and a true analog ladder network volume control for superb performance as both a DAC and a preamp.
