Got Vienna Acoustics Mahler speakers - what amp?

I have the Mahler's and they are definately power hungry. I would not want to use a 200 watt or less integrated with mine. But I like listen to mine at concert levels, that is what big speakers are for aren't they? The wattage seems to be sapped up to me. I have a Mac 300 watt and I wish I could afford their new 500 watt mono amps for them. They are a soft bass boomy speaker with those dual 10" woffers on them. Definately not a speaker for tubes. And they are not bi-wireable. My Mac amp seems to work fine together with them. They are not a good rock speaker because of the extra bass kick on them. But they excell on classical, jazz, and bluegrass that I play.

the best iv'e ever heard the mahlers sound was with an ayre v3x amplifier,it really had a firm control of those 4 woofers,yet was very sweet in the mids & top end

I originally used Bryston 7BST's with my Mahlers and they worked well. I have since changed to Sonic Frontiers Power 3SE's and they control the bass very well for tube amps.
