I'm upgrading my receiver to a 45tx (picked up a remaining one at a local stereo shop) to go along with my Denon 1600 DVD player. Question: Which piece would do a better job with the digital conversion, the receiver or the DVD player? Is there anybody out there with both pieces that have done some experimenting? Thanks! Follow up question: I have not taken advantage of the DVD-audio capabilities of the Denon yet, but hope to shortly. Does that require the analog connections to the receiver?
