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

Hm. This explanation is very different from the one you gave several years ago.

I'm very open to the idea that there are new vistas to be explored. That's why I have patents. But I think you need to get your story straight.

One problem with your story is that you don't have a measurement means. That's a problem that anyone with an engineering background will point to; and like me they will find it odd that you've had a circuit to compensate for this 'effect' but you've not developed a means of measurement. Anyone can see that such will lead to QC problems.

So my advice to you is to develop solid repeatable measurements. You already have the circuit (allegedly); so it itself is your means of measurement, as if that was not abundantly clear earlier. It is this particular fact that will send up red flags for anyone with a logical mind.

" Hm. This explanation is very different from the one you gave several years ago."

I have made major advancements since then which includes the automatic focus system.

" One problem with your story is that you don't have a measurement means. That's a problem that anyone with an engineering background will point to"

As a matter of fact I have had to develop my own test equipment since there is nothing available on the market that can measure what I'm looking for. I have completed the virtual analyzer as a computer model that easily shows the degree of resolution expected in the hologram. It gives me telemetry on the auto-focus stage that includes its ability to focus down to what depth in the signal. IOW how sharp the image is and how far I can expect to project an object at a distance and still remain within the capture range of the velocity detector. I needed to know how tight the lock is on the fundamental.

If you increase the physical separation between your speakers - it has the same effect as pulling a projector back away from the screen thus causing the image on the screen to become larger. Since gain and distortion are proportional I wanted the auto-focus to have overwhelming control so that no matter how you have your speakers situated it always projects crystal clear acoustic objects..

As the resolution is increased it enables greater depth-resolution. IOW being able to have a fully rendered sharp image of a triangle at the back of the stage that does not "wobble" or smear do to unstable velocity at that distance.

" It is this particular fact that will send up red flags for anyone with a logical mind. "

As far as the red flags - they belong to the "engineer" that is having trouble trying to fit this concept into a conventional template. Of course it doesn't fit because there are parameters involved that don't appear in the text books they are familiar with. Unless they are forced to think outside the box it will never fit.

Eventually the text books will catch up at some point and include newer methods and techniques to achieve results that until now have seemed impossible.

" I love how he stays "in character" throughout the thread. This is high level performance art! "

Anyone who knows me knows that they will always find me in my lab.
This is my life's work and my passion which is why I have succeeded.

It is easy to stay in character when the character is telling the truth.

"The truth shall set you free."

I think both @atmasphere and @roger_paul deserve a lot of credit even if for nothing more than being so passionate in their endeavors. As Albert Einstein once wrote on a blackboard: “Not everything that counts can be counted, and not everything that can be counted counts.”

OK- so despite my asking several times it appears you did have a measurement system after all! Why didn't you just come out and say so the first time I asked?

Air is anything but a constant when dealing with the speed of sound. Humidity and air pressure both play a role. Do you have compensation for pressure and humidity?

I'm having a problem with several other comments here as well. One was the speed of the power supply and another was the speed of the amplifier. Long ago I discovered that any power supply has a timing constant and if the amplifier goes lower than that constant IM distortion will rise. So that is a rule I've been careful to follow. But from your comments it sounds as if you are talking about something else. 

Also the speed of the amp is another area that is well understood. Are you referring to the speed of the amplifier as propagation delay?
