Re: Dan, a serious question

And don't take it the wrong way, please. ;-) And a definitional note: when I use the term "zero feedback," I'm talking about loops, not single stage degeneration.

Your description sounds (uff!) very much to me like my subjective impressions of zero feedback SE triode amps (and, to an extent, the zero feedback stuff like the Pass diy designs). But the distortion spectra correlate very nicely to that impression- it gets pretty ugly when any power is actually demanded. Now, that disclaimer made, do you get the same impression from zero feedback stuff that keeps the distortion low up to a reasonable power and has reasonably low source impedance?

I ask this because I've played with amps and preamps that have zero feedback and hold their distortion down, and in those cases, I get none of that congestion.
