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.

Without a doubt the coolest running amp at close with fantastic tube like qualities is the Harmonic Precision 110. I have them and the lack of heat is phenominal. They are more than 97% efficient. Despite the power rating I am running Revel Studios with them and the dynamic output is fantastic. Large room and as they have broken in I have had to continue to lower the volume on the preamp and I like loud. I have the Rowland MF 5600 on another system and while I think it has a really sweet sound must say it runs really hot. Check out Haronic Precision at www.audiopoints.com.
How about a cool running tube amp like the David Berning ZH270? You might even like it enough to use it in the winter too.
I don't know for sure, but I would guess the digital amps from TacT and others might be the coolest running amps.
Llano designs. Check website through AudiogoN. You can actually call and speak with Randy White. I've got an older version rated at only 100 watts and it feel like at least double that. If I had the money right now, I'd go for one of his new hybrids
I'm surprised the PS Audio HCA-2 isn't mentioned more. It is completely transparent and never runs out of driving power. I think it sounds better than the Bel Canto's I've heard. And it costs much less. Oh yeah, it's always cool to the touch.
