Yamaha wxc-50 right? I opened the manual and it doesn't look like it supports coax. So that makes the decision easy right?
Even if it did support both:
It would depend on the bit depth the two interfaces support. Given the same bi depth I think optical is preferred since it guarantees there is no ground loop.
Hmmm, looks like your correct....I just saw the digital coax plug, but reading online it appears it's only a output not a input.
I think the digital coax has a higher bit depth compared to optical, but not sure that it means it sounds better.
Either way, looks like I'm stuck on optical unless I do the d/a converting with the computer and go to the wxc-50 with rca. Hmmm, I wonder which would be better the wxc-50 or the audio of the Asus x99 Dekuxe ii motherboard?
