Well after talking to a friend of mine, he said that unless the cables are going over long distances, the coax should be at least as good as optical, because other wise you have to go from electrical to optics and back again, which makes sense.
That being the case a lot more of the integrated solutions come back into play including the NAD T754. Hmm, I thought Yamaha is another company, whose products were more feature rich and sacrificed audio quality, which you can find in Best Buy, though I could be wrong. I wonder how much audio quality I would sacrifice on my proacs in using the Yamaha instead of say an NAD. I eventually plan on obtaining a high end CD-player, so I would not want to skimp on the 2-channel audio quality.
