Are future improvements in Amp/PreAmps slowing to a crawl?

kosst,

Do you think that after decades of work trying to analyze the tiny events that lead up to the production of harmonics that I'm going to say
"Oh I know - I'll just use negative feedback - why didn't I think of this before?"

Ok here is a fact:
If you see something and react to it and use a countermeasure against it to "fix" it you are applying some form of negative feedback.

True.

The trick is where do you apply it and to fix what problem?
There is no "loop" from output back to the input.
I don't monitor voltage fluctuations seen on the vertical axis.
I use a form of feedback that involves shifting phase by micro-degrees at a particular location in the circuit that will allow this type of correction to be effective in stopping distortion from happening. This type of "feedback" is 1000 times the potency of classic negative feedback which we know does not work.

The Auto-Focus by default could not "automatically" focus anything unless it can detect and react.

Classic NFB can only suppress harmonic distortion to lower levels.
My circuit "correction method" stops distortion all together.

...are all issues directly related to harmonics?
NO - All issues are related to nonlinearity (NL) which caused the harmonics.
Harmonic distortion is one by-product of a NL circuit.
Imaging suffers even with the slightest amount of NL
A holographic image certainly cannot be maintained in such a circuit.
