"tube" cd players?

Hiya, who makes a good tube cd player, and how would you compare them to "regular" cd's? I have a Classe ca300 amp and classe cp50 pre and am looking at getting a cd player of equal quality. I have heard so much hoopla about the player, don't know which way is up. I have BW N804 speakers, Cardas and HT pro-silway xlr interconnects. Been using a cheap Technics cd player. I friend of mine recently purchased an expensive player to his relatively high end equipment, and said it didn't sound any different than his cheap Marantz?
