Has anyone heard the new North American products preamp and amp?

Roger, by your own definition at least some of the distortions I am referring to - the ones separate from amplifier distortions - are DYNAMIC. Seismic vibration or any vibration, e.g., transformer vibration, motor vibration, that produces jitter in CD playback or that affects the signal anywhere in the components or cable produces dynamic distortion, no?  Vibration is not static. Same with room anomalies, comb filter effects are dynamic and produce dynamic distortion, no?  Magnetic fields are not static and produce dynamic distortion, no?

I was mostly trying to separate the phase based errors that are found in crossovers and the phase characteristics of IC's with regard to affecting overall tonal balance of a presentation. Like the highs traveling on the outside (skin effect) and how it can warp or tare at an image in a fixed way.

There are other dynamic issues as well with cables when they pick up vibration of course and any effort to control the vibrations (anywhere) is desirable. 

It has been my experience that velocity based  "electrical modulation" in the amplifier chain were absolutely startling when removed. I would consider it a whole magnitude higher in the destructive property compared to mechanical vibrations. I know that with a constant velocity amplifier all the other issues seem to be exposed more easily.
It is quite surprising what happens when the music signal is allowed to flow steadily along the time domain without circuit induced contamination.

In fairness to your comment - I stand corrected.

That was no simple - It takes control at quantum levels to achieve this function."

At quantum levels? Do you mean nanoscale? Are you doing something quantum mechanically? Or are you just fond of the word quantum? ;-)
