Hi Dave
I have gone through a string of (I think) 5 or 6 CD players prior to the recent acquistion of a Cary CD303/200 tube player.
I have not heard the other tube players mentioned above and I am certain they are all good players, however for me I have never heard more analog sound from a CD player. The sound is just so non-fatiquing and liquid with a good solid bass output and extended highs. I have been very satisfied.
Whatever your choice, good luck and enjoy.
Regards,
AEW
