Anyone recommend a neutral tube amp?


I've been wanting to move to tubes for some time now. Lately I've changed most of my equipment. I now have a Rega Saturn CDP and some very revealing Opera Callas monitors. My amp is the Sim Moon 5.3 integrated. I like the neutral character of the amp, it simply takes on the characteristics of whatever is being played through it. Can anyone name a tube amp that is similarly neutral, that won't color the sound of the CDP?

The Coincident Technology Frankenstein II is the finest most neutral tubed amp available at any price. It may be purchased directly from Coincident Technology. The asking price is a bargain. I have had mine for over 1 year and I have never "looked back."
there is no neutral amplifier. a well-trained listener can detect coloration after auditioning an amplifier for some period of time, with a variety of recordings.

my experience with my mac 275 indicates that the amp has e very minimal coloration.
Cayin A88t integrated, or other similar models, cheap enough to keep for a doorstop if you don't like it.

Very, very, very good sounding for the money, and flexible.
Remote volume and triode/pentode switching...

Good solid sound, and makes audio fun again.
