many like no global negative feedback amplifiers and agreed super symmetry will eleminate much of the distortion.
In general many say no global feedback amps sound better but what is the reason behind why papa is not behind zero feedback amps?

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'm still/always available as a subject for the evaluation of any new designs.
I'll be happy to provide the feedback! 😀

I may be in the minority but I don't have a problem w feedback (global or local). Done judicially when a circuit is already low in distortion sounds fantastic. I don't hate if the circuit is well throughout
I don't think he realize it. Otherwise he would not ask the master zero gnfb amplifiers such a question.
He typically starts the thread and then leaves...
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.
Supersymmetry does not necessarily require GNFB. It does require a
symmetric pair of loops, but they don't have to be global.
