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.
