In reply to:
Y, your original question appears to be based mainly on possible differences between the DACs in the player and in the receiver. DACs cost the equipment manufacturers roughly $1-$10 apiece and have reached a high state of excellence. Although there are measurable differences between them, it's highly doubtful whether they create audible differences in the real world. My view is not to be concerned about the matter, and if you're using the coaxial digital connection, continue to do so.
There is definately a difference in sound between using my Pioneer DVD players DAC's and the DAC's in my Rotel. I currently use the optical output of my Pioneer, because my Rotel DAC's sound better. When I get the Denon 2900 I'll check again.
