"Prune"

As for the circuit being PP, I don't see it. Each side drives a
separate electrode on the headphones, but each electrode is driven SE.


** The HP operates differentially, so reducing or eliminating even order
harmonics generated in the two, anti-phase amplification stages.


A differential output amplifier is not the same as PP since the side
pushing is on the other side of the load from the one pulling at that
time.


** A simpler definition of PP is hard to imagine.
