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?

Eagleman6722, if you look in the DIY forums, you will see that people are commonly swapping op-amp chips out in their equipment and projects because certain ICs have a 'sound' they are looking for or trying to reduce. This is not a tube/transistor thing, its simply a component thing.

IOW you can no more say a tube amp has the character of certain tubes than you can say that a transistor amp has the character of certain transistors (or ICs.). The only thing is, in tube amps, they are a hell of a lot easier to change :)
Any amp made by Leben will make you realize that "warm, tubey sound" is a cliche.
A thing of the past? And why not? When you listen to the Leben, you wonder what new technology has added to realistic sound? Turntables are old technology! Yet, look at the resurgence.

I own the Leben CS600 paired with Rogers LS3/5a (15 ohm) and I can tell you the sheer musical experience is wonderful!
Denjo, what I meant was, that the idea that tube amps were warm and coloured was a thing of the past, not tube amps per se. I have nothing but tubed gear in my rig.
