You realize that I have numerous designs using ZGNFB, going back to
the Stasis amps at Threshold. At Pass Labs ZGNFB was applied to the
early X amplifiers - X1000, X600, X350. With the X250 we applied GNFB
and have used it in the X amplifiers since.
At First Watt, the F1, F2, M2, F4, SIT-1, SIT-2, and SIT-3 are all zero GNFB.
The other amplifiers have global feedback loops.
The decision to employ loop feedback around the output stage has always
been based on whether that particular amplifier sounded better that way.

I don't think he realize it. Otherwise he would not ask the master zero gnfb amplifiers such a question.You realize that I have numerous designs using ZGNFB, going back to

He typically starts the thread and then leaves...
@rhythmsandy
do you know what is zero global negative feedback amplifier???
I do understand local feedbacks and global feedback.
Yes I do know but I was in just a question that when it comes to super symmetry how is GNFB is not the primary parameter instead add two GNFB.

Gives me a chance to toot my horn...

Supersymmetry does not necessarily require GNFB. It does require a
symmetric pair of loops, but they don't have to be global.

- why zero global negative feedback amplifier not observed in pass designs?
