RE: At best Cheever defines the euphonic, not the accurate

"You are making the same faulty assumption as many engineers that if you push the distortion low enough, regardless of HOW, it should be "perfect". BUT there is no zero distortion with non-linear devices, ever. That means you have to make sure that the distortion is shaped in the way that it is least audible...to HUMANS."

I am, as usual, very much enjoying your thoughts on amplifiers but I would like to comment on your statement above. While I think that I know where you are 'coming from', none the less it is simply, logically, not true. I also believe that you are making several assumptions that you may not be conscious of because those awful engineers are actually right.

First-off "perfect" doesn't exist other than in the sense of meeting Specs. Except for the identity case (I'm THE perfect example of myself) we are stuck with limiting variations sufficiently that stuff will "do the job". In this case the job is to have inaudible distortions.

With adequate loop bandwidth and gain the in-band distortion will asymptotically approach the error amplifier's which can be very clean.

The best solution to a problem is a function of the system constraints and there are always trade-off's as with everything else in life. So while your approach may be best for a particular ilk of designs it certainly isn't a given...
