Seeking Great Cool Runnin' SS Amp...

Advice Appreciated! I'm running Proac 2.5's with either a BAT VK30 or Rogue 99 Magnum Preamp, Arcam FMJ CDP, Linn LP12/Itok TT, and a Bruce Moore tube amp. I'm looking for a cool running SS amp for the summer months here in Arizona. Why? I can justify to my girlfriend a spaceheater during the months we heat the house, but she is opposed to excess power use otherwise. Why REALLY? This allows me to play with different amps, different sounds, for fun, seasonally! And I too believe in not wasting energy if not necessary.

So, I'm left with searching for a cool running amp (not Class A). Any suggestions? Right now my short list includes the Oddysey Stratos Dual Mono, the Plinius 102, and the Ayre V3. What would you recommend for this system, and why? Thanks Alot.
