Home Amp/Preamp Asylum

I'm drawn to Putzeys' conclusions at the end "The F-word"

Unfortunately my lack of technical and math savvy means most of the article is mumbo-jumbo to me.

Putzeys's final conclusions, viz. that is essentially that there is no such thing as too much feedback, and that includes multi-stage feedback loops as well as local strike me as valid based my listening to my Purifi amp. ("Degenerative" is term I hadn't hear before reading this thread).

E-Stat got on about the supposed inherent linearity of amplifier components which you, Duke, addressed. However E-Stat's fundamental agenda is anti-feedback in general; this is misguided, IMHO, based on Putzeys and other commentators of the last couple of decades. E-Stat's archaic views on feedback are the basis for his categorical hatred of typical, integrated op amps which is, according, also misguided.
