Whic CD player would you pick and why

I am looking to add a better CD player to my system. My current system consists of Mcintosh Amps the 402 and the 502. The pre-amp is the Anthem Statement 2 The cd player is the Moon Equinox.The speakers are the Martin Logan Vantages. The CD players that I am looking at are the:
Ayre CX 7e
Mcintosh Mcd 500
Linn unidisk SC
Esoteric Sa60
Cary 306
I am a Jazz listener and enjoy feamle vocals. PLease share you insights of the pro's or cons of any of these players. I am willing to spend 6,500. on the player.
Thanks for the insghts
