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.

Just got my VAC 450 monos back from Florida after having an on-rush circuit as well as auto-bias circuitry installed in each amp, plus a few more tweaks that remain confidential to VAC.

After only a day, I now have startlingly realistic sound, unlike anything I have heard anywhere. Tight, commanding bass, extended sweet highs, great imaging, PRAT, etc., etc. Best bass I've ever heard from a tube amp anywhere, as well as the legendary VAC mid-range, with imaging and musicality to spare. Definitely get my vote in the tube "kick-ass" category.
I heard a system once with DCS source, VTL pre-amp, and hefty VAC amps driving Magico mini speakers in a smaller dealer demo room. THis combo was uniquely striking and reference quality in particular in its ability to deliver orchestral strings from standard CD in an exceptionally realistic sounding manner. So it "kicked ass" in that particular way, and was no slouch otherwise as well. The VAC monoblock amps were particularly striking aesthetically as well. Dealer mentioned some kind of automatic tube bias system in the VAC gear. DOn't know the details of how that worked, but it was working quite well that particular day.
Fplanner2000 - VAC rules the roost for me. I've never heard anything better - including ARC, Mc, VTL and numerous others. I'm saving for a pair of VAC phi200's.
Add me to the recommendations for VAC amps. I have a Phi 200 and have barely had it break a sweat in my small room driving Nola Micro References, which are not a particularly easy load. It has all the power and bass control you could ask for, while still being one of the most realistic and musically involving amplifiers I've ever heard (ranking up there with Jadis and Lamm in that respect). The monos would be even better, if your room is large.
check out Jolida's fusion monoblocks at 200wpc. seems like some serious tube amp. and you could get both for about 5k.
buy both at the same time. see posequipmentsales.com.
brian will be very helpful. just a suggestion.
