First, I'm respecting philosophy of PPL.
His work is precise, and very close to people who is making effort to understand his amp.
PRII has exceptional appearance and sophisticated enclosure,
LISAIII is giving opened source and incredible architecture in it (this amp is also opened....see below).
(This is permited; push to enlarge)
But local feedback is omitted by final update, because it's needless.
It was very difficult task to reduce DC in output w/o DC servo.
I applied architecture which is resembled A47.
The architecture has double compensation caps to prevent oscillation.
That makes forwarding phases with double crossover, and miracle sound for me.
