Good to see that you do understand the problem. I did some power amplifier design for both audio and electron beam deflection over 30 years ago. For audio the more troubling problem was crossover distortion as the output switched from the plus driver to the negative driver, most noticeable as distortion at low volume levels. That is why at that time we needed to have both drivers conducting (even when at a quiescent state) to minimize the crossover distortion. This is what contributed to lower efficiencies at low power levels and with the power transistors then available, could lead to thermal runaway. Negative feedback helped reduce the distortion but was always susceptible to becoming unstable depending upon the amplifiers load. I am quite sure amplifier design has greatly improved since those days.

 

You can run a car with an alternator, but no battery. Same can be said the other way around, but it won't last long. The alternator is what powers your stereo, once the alternator is maxed out, the battery gives a hand.
