Jerry, I'm afraid you didn't quite get the gist of the DVD-Audio question; DVD-Audio is a particular type of DVD that only has (uncompressed) audio on it; usually multichannel audio. That is normally hooked up with 6 coaxial cables with RCA cables on each end, although if you have both a player and receiver from Denon (and some others, I think), there are proprietary digital links (firewire, DenonLINK, etc) that will carry the whole signal without the extra cables. SACD is a similar format.
