NAD C542 vs. Rotel RCD1072.

If anyone has heard/auditioned both of these I will appreciate your input.Although I have a NAD C372,and there would be some advantage there,sound quality is my #1 concern!Thanks in advance.
Doubtful there would be monumental differences between the players on their I have heard both in various systems...however the Nad would offer superior synergy in a Nad sytem and I believe the remote from your amp controls other Nad products...which is a bonus...hope this helps...if sound quality is #1 concern here are 2 used options at the $500 level:
denon 1650ar
