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

OK- so this sounds like to me that the correct answer to my question is 'no'.

With all due respect I'm still not sure what you are asking.
If you want to know the value of the output velocity it equals the input velocity +/- zero.

It does not add any acceleration or de-acceleration.

The sound of a circuit is the signature of how its velocity is handled.

Are you sitting down?

I can install an auto-focus circuit to control the velocity of a tube circuit and achieve exactly the same sound as a solid state circuit with the same auto-focus. They would both produce the same holographic images.

Let me ask a simple question of anyone reading this post. This might lead to an understanding of what I'm talking about. It also may pull your thinking slightly outside the box.

Do you know what part or area of a circuit determines the signal to noise ratio of the circuit?

Please refrain from wise guy answers. Thank you.

As I understand it Roger, you have a means of detecting this 'velocity' but what I found peculiar last time I engaged in this topic was that you had not quantified this velocity as a specification. I'm pretty sure you're not talking about risetime/slew rate.

The question is, have you quantified this circuit operation with a spec? Or put another way, have you quantified the 'velocity' spec?

At least you confirmed one thing- that you are not talking about risetime/slew rate.
