Amp for Verity Audio Sarastro

Hello my friends!

Recently I acquired the Verity Audio Sarastro and although I'm very happy with my amps concerning most of their attributes I would like more power. Actually I would like a lot more power. My amps, Mcintosh MC2102 and C2200 although they are very good with 60% of the music I'm listening they lack what is needed to perform rock music at realistic SPL's. My speakers are 93 db. So I suppose 200-300W would be more than enough. On the other hand I like the natural timbre my amps produce!

So my question is: What amp do you suggest that can drive my speakers to the limits even with music like Metallica with a sweet midrange? I would like to hear the kick drum as a kick drum but not lose the immediacy the valves produce... Am I asking too much?Lets say my budget is around 20.000 $ (so LAMM hybrids are excluded, hehehe). Opinions from people who have heard Verity Audio speakers with different amps would be highly appreciated.

Thanks a lot for your answers.

Regards,

Michael
