Bear you are a bad boy raising that old nugget !

I read the threads in a fair bit of detail. It does not switch at high frequencies, it can switch at low frequencies. It depends on the lifetime of minority carriers in the base region of the output devices. So those who say it does switch are correct, and those who say it doesn't switch are correct. Peace to all.

Thanks

I work on a zero feedback buffer like the krill

I found THD 20k 0.004% 1W and 0.005% 100W

Your circuit has impressive results from your simulations.

However, the Krill has two key features - in my opinion - that your circuit is missing:
a) Steve's unique biasing
b) Restricted charge suck-out of minority charge carriers which I believe is responsible for the great treble this amplifier is reported to produce.
