Electrocompaniet Nemo

My friend has the Nemos are there great amps.
Here's the thing i dont get.
There class A amps and when i put my hands on them, these amps didn't feel hot at all. How is that possible if these are class A amps?

Correction, I wrote My friend has the Nemos are there great amps.
I meant to say, My friend has the Nemos and they are great sounding amps. They sound very smooth and dont get hot at all. I'm just trying to figure out, how come the amps dont get hot, when their Class A amps.

Unsound, thats what i was thinking that the Nemo amps are not pure Class A. I'm using the Ayre V1 amp which is a Class A/AB amp. Its one of the best sounding solid state amps. But you put your hand on the V1 amp and its very hot.
