Tube amps that kick ass?


I'd like to find a high powered tube amp that can deliver all the magic that tubes are known for AND that kicks butt. Solid, tight bass with good authority. Dynamic, quick, but handles the little information (micro) sweetly as well. A tube amp that will play rock and roll at realistic volumes – the way rock in roll was meant to be enjoyed - and still sound great.

Any ideas? 10K or under? preferably 5K or so

Thanks for all responses.

So in summary, the TRL GT-800 kicks butt of everything else that I have tried or heard, including the SS ams in the bass area, as well as any area of sound, subjectiveky and objectively alike.
And at $140,000 (14x-28x the max Keithmundy is looking to spend), of what relevance is this information?
Darkmoebius, the thread evolved from the original question, and several amps mentioned were also out of the intended budget. I listed other amps to indicate the *relative" butt kicking.

The Audio Valve Challenger can also kick butts.

Moreover, list prices hardly matter any more, thanks to audiogon.
Thanks so much to all who have responded.

Yes the GT-800's are going to be slightly out of my budget! but those are great pictures GD. Do you need anymore friends?

Keith,

why all the concern about high power with the 5A's? Ok, there are some demands down around 100Hz but most of the heavy lifting is being done by the sub's plate amp, which I hope is also rolling off the woofer just about that 100Hz. Anyway, I would be more concerned with synergy than just raw power numbers. You just may be surprised at what the "right" 50 watt/ch PP (or OTL) amp sounds like. Good luck with your search.
