Moonriver Audio 404 Optional USB DAC module
What was desired for our USB DAC module was not to make an addition rather than an omission; instead we had to be confident of substantially raising the true value and functionality of Model 404.
Some key features; state-of-the-art XMOS USB asynchronous interface; AKM 4490 DAC chip; separate high-precision clocks for the 44,1K and the 48K sample rate group respectively; supports PCM streams up to 384kHz. USB, D/A and analog out section each one fed by its own dedicated power supply. We work hard to get the best possible sound performance and we believe that this USB DAC is a enormous added value to the Model 404 amplifier.
