I bumped into Barrie Gilbert's scarifying article and followed the thread...then realized that it was just a nightmare when I woke up in the real world where much simpler op-amps and way much simpler amplifier circuits sold by the billions since the 60's are good enough in the audio world...
Honestly...I'm going back to the 3...5 transistor amplifier world that used to delight many generations instead of simply mixing wi-fi amps world with DIY audio pleasure just to show off who's IQ has a higher slew rate...
