Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

Indeed, (though Pass doesn't agree)

Pass says, "Negative loop feedback creates higher order distortion harmonics, and there seems to be an implication that you might want to use lots of feedback if you plan on using any at all. Some designers look at it this way, others to use feedback sparingly, and some refuse to use it at all."

He fits indo the "use feedback sparingly" school, in support of which he shows this graph based on his own experimentation ...

?

I don't see how this supports "sparingly" vs. not at all, but it is worth noting that he only tried 15dB of feedback, not 40dB.
