CD Player for Cary system, pls...


Hello Audio Experts! I have a Cary Cinema 6 pre, AVA Ultra 350 amp, & Marantz CC4001 cd changer system. I want better cd sound. Could I have suggestions for a better single cd player, or a DAC for use with my Marantz? Which way should I go; how much will it cost to better my sound, and which units would you all recommend, please?

TIA! Murf

Thanks Folks, I would love to get a Cary cd player since I think my pre is so good. But prices are pretty hi, and I haven't seen any for sale lately.
Yes, I definitely want to go second hand or demo (I'm poor). So I would like to see what other players might be a bargain and still better my sound (I am going digital to the Cary pre from the Marantz, using the Cary DAC).

There are 2 Cary CDP-1's for sale in the classifieds for $750.00 which is a great deal.No affiliation to either seller,just trying to help.
Darn, that's tempting! But I'm not..quite..ready....
Some folks here like the Rotel RCD-1520; WhatHiFi doesn't, but likes the Marantz cd6003 better. Another review didn't like the Cary so much, a little dull?
Don't know if I want to stretch for the Rotel, but...what do you experts think?
Decisions, decisions....
