The results have little to do with what you write as the 'reasons'
The amps have different designs, and different gain.
Perhas different input sensitivities and impedance.
The correlation of your volume knob and the areas you ask about.. there is no correlation that matters to the end result you want to know.
The way to see if one uses more A/C watts is to actually measure it.
Most SS amps of that sort have about the same efficiency (give or take some)
One way yu COULD see which is better would be to use an independent Db meter, like a Radio Shack model
(find still available on eBay. or other models on Amazon)
Then you could have an independent level control(using the meter) and know which amp is able to play louder without distortion.
You may be able to tell without the meter. Just which one plays louder without distortion.. It has nothing to do with the volume knob numbers.. And does one sound better when playing at very soft volumes. regarless of the volume knob numbers. Play each at the softest you can hear.. does one seem to be clearer?
Anyway,, hope this helps.
Then one that sounds better IS better.
