Sandy, did you actually build your amp?
Or do you have any updates on it?
Do you consider your latest published version as final, and worth to actually build?

VFA amplifiers have many more advantages in audio.
And a comparison between CFA / VFA

invalid request, I guess?
So far I avoided CFAs, because usually they require DC servo...

Current feedback amplifiers have great potential. I also made my own version of a similar amplifier. In such amplifiers, the output impedance is close to ohmic and to stabilize the operation, a small inductance is enough, and often it is not needed at all.
This is the scheme with which the simulation works
HV = V + 10V minimum
V can reach up to 70-80V with the transistors used.
HV 80-90V
HV = V + 10V minimum
V can reach up to 70-80V with the transistors used.
HV 80-90V

With CFA, ground loop breaker causes inter channel crosstalk and it will with your circuit also.
The effect of dynamic Zener capacitance is used . Bonus a small limit on the maximum current of the output transistors in short circuit mode
Используется эффект динамической емкости стабилитрона . Бонус небольшое ограничение максимального тока выходных транзисторов в режиме короткого замыкания
