Recommend CD Player with Volume Control


I have Magneplanar 3.6Rs and Classe CAM-350 monoblocks and am looking to add a CD player. Since this will be my only source, I am looking for a CD player that has volume control/variable output and I will bypass the preamp. 24 bit, HDCD, and upgradability are definite advantages. Any suggestions in the $2000 price range (new or used)?

I hate to be in disagreement, but I bought a CD50 to see what all the hype was about. I was completely disappointed with it, in fact I found that a Rotel 855 was more enjoyable to listen to. I tried it on 3 systems and it just never sounded right to me, I'm not saying that it is a piece of junk, it does some things extremely well, but overall I just didn't like it. Wadia sound is much better IMHO. I have one used in mint condition for sale now on Audiogon if you are interested.
