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.

Check out the Arcam DVD-139 listed on Audiogon.

No interest or relationship to the seller.

Neither. Get rid of the Marantz. There's nothing wrong with it but it is clearly the weakest link in your system. Something like a matching Arcam integrated would make a huge difference in sound quality.
I had an Arcam AVR100 but it developed a buzz I could not resolve. What if I added a nice amp (was looking at the Parasound A52)- would that improve sound or would it just magnify the Marantz?
I second the idea of getting the Marantz out of the chain. I used a Marantz 7001 AVR as a preamp for a long time, and when I finally got a real two-channel integrated (Cambridge 850A v2) it was like someone took a blanket off my speakers.
