Via coax-out, everything works fine. Via USB-out, Onkyo HF Player is more stable than UAPP, but they both has small glitch from time to time. Unless you are into streaming, I think getting an X5III purely as digital transport is kind of a waste. For a pure music playback digital transport for Mojo, I am more inclined to recommend Shanling M1, or Sony A30 series (or the A10 series if you don't play with DSD).
