Ayre amps - cool running?

Can anybody with experience with Ayre amplification tell me how hot or cool they run? I've had a big Krell, which was very warm when on but no music, and downright hot when actively being used, and I've had big Simaudio monos which were cool when on but no music, and only slightly warm under most conditions.

I think that your experience is in line with diff btwn amps that are Class A (run hot) and A/B, although some A/B amps are biased heavily into class A and will run warm-hot most of the time.

When I was using the Ayre V5Xe, it ran on the low side of moderately warm. My tube preamp generated a lot more heat. I never drove it hard so I can't speak to its temperature if it was really stressed.
Swampwalker is correct. It has to do with how the amp is biased. A TRUE class A amp runs extremely warm where a class B amp runs cool. AB fits in between and how much it runs into class A. Of course the newer Digi amps run cool.

I know the MXRs are only slightly warm when playing Watt Puppy 8s at high volume.
