RE: ALT. 1.

"The current draw in a Class A amplifier is NEVER, EVER "constant" when the amplifier is reproducing musical dynamics..."

Indeed, of course it isn't. As has been said many times, for an SE amplifier the current draw fluctuates in step with the audio signal. But the average current draw, averaged over the timescales of the audio frequencies in the signal, is approximately constant. (The current oscillates up and down around the quiescent current. Assuming there is no gross distortion, the fluctuations above and below the quiescent level, on the positive and negative halves of the audio cycles, are essentially equal in magnitude, and hence the average current is essentially constant.)
