So, now, I’m in a position to say this with no doubts: This definitely sounds better (but so much) BETTER than any other digital solution, mainly CD player (any one you want), CD transport and PC Music (whatever this is).
While your enthusiasm is great, and I agree that the power supply is very important factor, you obviously haven't heard a well done high-res CD/SACD/DVD-A transport or PC Music (computer audio). :-)
Also, what we do with the fact that both WD and O!Play media players downsample to 44.1 and 48kHz?
Best wishes,
