greenline,
I was in a similar position, as I had a 13 year old Nakamichi cd player, and purchased a Denon 2910 DVD player, which I now use exclusively for cd playback. I had both the nak and the 2910 hooked up for a while, and was hard pressed to hear much of a difference, if any. The nak then went to the bedroom system, as I have limited space for components in my entertainment center. Have been happy with the 2910, although it's for sale as I'm upgrading all my components. Am demoing a rotel 1072 cd player, which is a very nice player, but no difference in sound quality compared to the denon. if you do buy a dvd player, I would recommend getting one with DVDA/SACD capability. I was a skeptic at first, but I can notice an improvement in sound quality in the two new formats over redbook cd. And the video from the denon is very good, to the point that it removed a new tv from the current wishlist.
