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?

I agree, I think balance is a much more important attribute, sounds better in more applications, and causes much less fatigue and boredom in the long run. My CAT JL2 is balanced top to bottom, as is my ARS Sonum integrated, yet they sound quite different, the ARS is "warmer" to some extent, but both are balanced through the frequency range. I have no idea which is more accurate though.
Do any of 'em take in a 1 KHz and a 10 KHz square wave and output a reasonable facimile of same?
Hello Mrtennis, in fact I'm not expecting a perfectly neutral tube amp. Such a thing probably isn't desirable, never mind attainable. One of my purposes in going to tubes is to get some of that tube warmth. However, I'd like an amp that doesn't much alter the basic characteristics of the source components. I'd like an amp that is more quick and tight than the "traditional" tube sound.

If anyone has suggestions for an integrated, with appropriate power, that would be very welcome.
hi rfprice:

as i have indicated on this thread and in my previous comments, you should have no trouble finding a tube product in your price range which does not have the traditional tube sound. most amps are designed to be colorless. in my own pursuite of a vintage sounding tube amp in current production, i have not found one. this my loss is your gain.

pick an amp, and it will probably satisfy you. don't worry, euphonic coloration and bloom will not likely be the outcome of your selection.
I just started playing with a Music Reference RM10 MKII ($1950)which is a wonderful little amp and an incredible bargain if 35 watts is sufficient (I also listend to the RM9 which has a similar sound signature if you need more power). This is defintely in the neutral camp, and in the best sense of the word.
