NFB and Joule OTL

Thorsten, I also yield to your knowledge of circuitry (about which I am woefully ignorant). I would merely like to point our that Joule OTLs have a knob that can increase/decrease NFB, although I do not know to what degree. That said, I find this amp exceptional (the VZN-80) and for the record, I also use Welborne Laurel SET and Manley SET/pp amps (in SET mose, the Manley also offers controllable NFB). Proper mating with speakers is, as we all know, the key element.
