Thanks for the response. Am I correct, if C5 is increased, then the frequency at which feedback is reduced is lowered? It's a simple enough circuit to try it. I am much more interested in reducing output Z than in lowering distortion per se. This would allow me to run my ESLs without the Zero autoformers (or not, if I don't like the effects of NFB on sonics). As you probably know, there is no problem with ESL impedance at low frequencies, where ESLs have very high input Z. With my Sound Labs, the impedance problem only arises in the mid-band, from about 500Hz to about 2kHz. I wonder if one could design a NFB network to work in the midband and not in the bass OR extreme treble, without destroying the magic midrange sound.
