I think you will find the rotel 971 hard to beat. Probably you can get it for under 600$ with a little effort. HDCD and imho a more balanced presentation than the adcom.
Best CD player for $700.00
I need to upgrade my old CD player (Mag CDB 650). I am considering the Adcom GCD 700 which lists for $700.00. It sounded very warm and open. What are some other alternatives and how do they stack up to the Adcom. Your help is appreciated
