In Reply to: Sony TA-A1ES Class A Integrated vs Rogue Cronus Magnum KT120 Integrated - pics posted by AbeCollins on July 23, 2014 at 22:20:08:
For what it's worth, I took some power consumption and heat measurements with the Sony sitting idle.
The power draw is about 121-Watts steady state, no signal. That's rather high for a compact 80wpc amp indicating it is at least 'biased highly toward Class A'. For comparison, my 150wpc Odyssey Stratos amp drew about 70-Watts steady state at idle.
But I'm not one who believes that Class A amps necessarily sound better. They should but that's not always the case. My 300wpc Ampzilla 2000 2nd Edition monoblocks each draw about 65-Watts at idle and they sound incredible.

Temperature over Sony heat sinks about 119 degrees F. For comparison the Pass Labs X150.5 I once owned was about 122 degrees F.
