Perhaps that's true for a contemporary amplifier that's class AB. Old-school class A is a room heater when it's on and is off when it's off. Lots of middle ground, I suspect.but when in the off or idle mode i doubt that really save that much power. when cranking out music yes they use a lot lless but i think idle current is going to be close.
