What are the best CD Player around $3500?

SimAudio Nova, or used Eclipse - if you like a good SS sound.

Why no mention of the Gamut's MKII cdp??
Anyone have opinions on this??

Probably most of the players listed will do a great job. Your jvc player is holding you back so much that all will be a significant improvement. Do you have the opportunity to listen to any of them? I have heard the mac, ayre and cary and could live with any of them. I would rate the cary first, ayre second and the mac third. Resolution with the cary is the best and the sound never gets too etched. I have the same amp paired with von shweikert vr4 jr. The front end I decided to go with is a $500 dac mated to my dvd player. I am extremely pleased and have yet to find something that sounds better.

How about a used wadia 860,

Having owned the 6900 for several years and with a few different CDP's (XA777ES, MAC MCD 205) I would say the the 6900 will make nice music with pretty muchany of the CDP's you listed. I do not think it will mate poorly with any of them. Of the ones you mentioned I have only heard the G08 (with the 6900) and thought it fantastic.
