My original point is that you're wrong to say that power consumption
of a an amplifier is "equally (as in 50/50) dependent on both" the
volume control and impedance of the load in all circumstances.
The point is that the amplifier can't "push" any more power than
the I/R limits of the source and load impedances. However, it
also can't "push" any more power than the input signal multiplied
by the gain permits, either.
Which, is true, but still entirely irrelevant to the discussion at
hand (i.e. mp3 player's headphone output feeding a high impedance
input of a receiver).
