Mike's not alone with having tubes somewhere in "there". Perhaps a tube preamp for the Hegel?
I know you love the Classe' CP800 but just sayin.....might be worth a little experimentation-venture?
Mike, when I had my Revel's with ARC REF 250's, I shot this video:

Some will likely say this just proves the meters were inaccurate, but let me tell you, the amps weren't breaking a sweat and sounded incredible.
The REF250's took the Revel's to a totally different level and proved just how ballsy these amps are. The synergy was scary good. I also had 2301's on my Salon 2's.
I know Joe had CJ monos on his Revel's and Bruce had Mc 275's on his Revel's.
