I have an Ultech ucd-100 and want to upgrade?

Hi - My cdp is pretty good, but I want to upgrade. My wife won't let me spend too much extra money. I was thinking about a Adcom GCD-750 because it has balanced outs. This would maybe sound better since I have my Proceed pre and my Classe' amp connected with balanced cables. Please help!! Oh by the way I really like Hdcd.
Thanks Jim
