Pass Labs XA25, i heard the sound transparent timbres from XA25, the third stage of amplifier, who know it was used feedback to the JFET?

Post the schematics so we can understand what exactly are you asking.

I dont think this amp uses global feedback and Papa got rid of degenerative feedback. I'm sure someone will correct me if I'm wrong though........

We removed degeneration but use a global loop for feedback.
