For the Krell KSA-50S I measured steady state 800-watts power draw from the AC mains for a sustained period of time with music playing very loud.... and continued 800-watts power draw for several seconds after the input signal was removed. This had to be Class A operation for a 'mere 50wpc' amp. And yes, the heat sinks got very hot.
I measured close to 250-watts steady state on the 30wpc Pass Aleph 3.
So the Sony is not pure Class A but that's fine by me. I'm not convinced that Class A operation is necessary for outstanding music reproduction as I have heard several incredible sounding Class AB amps, and some Class A amps that weren't exactly fantastic.
