effect of tubes in cd players


some cd players have tubes inside. Does it change the sound a lot like using a tube preamp?

Anything that colors the sound or rolls it off is what I'm trying to eliminate, of course without adding sibilance or harshness.

Steve have you ever heard Wytechs? These tube amps (all SET) have the most bass I've heard of any tube amp. Very fast, tight, in a word, perfect for my tastes. No bloat. A real treat to listen to them.

When you mention you modding the Shanling and the SS turns out sounding better, is this with modding the tube stage as well? Have you thought about disconnecting the headphone stage and coupling these transformers to those of the tube output stage?

I prefer the tube stage of my cd player to the ss stage, but if the tubes aren't right, the ss stage will best it (and I've gone through 3 series of mods so both sections are modded out the wazoo).
Never heard the Wytechs. I have heard the $250K Wavacs. Now these can do bass for real, and tight.

Yes.

No. I try to avoid both transformers and capacitors if possible, particularly transformers. This is because there are so many good choices for coupling caps available now. I try to DC-couple whenever possible, such as my mod for the Benchmark DAC-1.

I have had three solid state players, Sony, Rotel, and Marantz. I went with a used Cary Audio player this time and I will not go back to a solid state player. One of my audio friends has a Ah Toeb player, this is also a good sounding player.
