Vinyl is analog, everything else is digital. Not sure if it was imagination or not, but it seemed that CD playback (from an inexpensive 200-disk changer) sounded just the tiniest bit better via digital coax even after matching SPL.
The digital path seemed to play 1-2 dB louder than analog, so it's possible that my perception was skewed by the initially louder digital playback. My friends and family have a very limited store of patience for helping with blind testing, and I have an equally limited store of free time.
