Upgrade CD, New CD or Universal Player?


I have an ARCAM CD72 and a Marantz 6005 AVR driving it. Got new B&W 683's but do not hear a huge difference when playing CD's. Is it better to upgrade the CD72, get a new CD player or go with a universal player? I have read good things about the OPPO BDP 95 (we have a BDP 93 for home cinema). Thanks for advice.

FYI, I appreciate the advice. Going with an Integra 40.2 for the pre-amp, and a Parasound A52 for amp. Got a deal on both.
I don't know much about the 40.2 but the A52 should make a very big improvement in sound quality. Once you have a chance to listen your new gear, please post and tell us what you think.
