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?

Neutral tube, my personnal choices would fall into three brand camps.
European: Tron to Audio Note
American: Wavestream (Scott Franklin) to VAC
Canadian: Wytech to Coincident Technology

Note a neutral detail choice vs a more subtle neutral choice in each camp.

While not a tube pre-amp and basically not available the CTC Blowtorch struck me as shockingly neutral.



The cj premier 140 is quite neutral, but still sounds like tubes.

If you want a tube amp that sounds like SS, listen to a Sonic Frontiers Power 2 or VAC PA 100/100. These two amps combine what is NOT good about both technologies.

The KR Audio tube amps with their reverse hybrid design are very neutral ranging in power from 20-100 watts/channel (actually one version at 200W).
Thanks for all the responses thusfar. Tim, you're right to be concerned about the 87 db on the speakers. I've found some amps, such as the Mac 275, to be underpowered with them. I once heard the ARC 55 watt integrated and I understand what you mean by "aluminized." However oddly, that 55 watt amp drove the speakers very well, unlike the 75 watt Mac. I've heard the Atma-Sphere talked up often. I'll have to look around for that. Unfortunately the dealers in my area don't stock much tube gear.
