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

Anyone is free to talk about whatever they want.  

There  is validity to the theory that any publicity is good publicity compared to none at all.  

Roger, I for one, have enjoyed you explanations very much. Thanks
for trying with the folks who are just trying to disrupt real conversations so they can be saying something, anything in public. Despite the fact that there is only 10 people reading the thread. Flies at a picnic.
Of course, hearing an amp is the only way to know how it sounds, and it is natural to ask questions. It is always best to listen to the answers instead of feigning incredulity.
I am happy to be wildly enthusiastic about you decades of effort and your inventions and have read the white paper a number of times. I saw nothing hard to understand... but I was trying to understand rather than looking for something to argue about in a rude manner, for entertainment! ??
Your further explanations left no doubt about the points you were clarifying. I appreciate your work very much! I carry an equal amount of distain for Trolls who crop up on every Topic with nothing to Add. 
Good news is that even absurd questions netted interesting answers.
Thank you Roger. I anxiously await your industry changing products to arrive at my home.

True, however, wrong information is worse than no information. :)

gdhal, Good information is evidenced by it working, this is the theory part of the scientific method. There is also good reason for a designer to not really tell what is true.

I have been able to greatly improve the sound of Roger's amp using the new Star Sound Tech. 2.5AP-1AINT audio points under it rather than their old 1.5AP-1 INT Audio Points over 300,000 of. Furthermore their new APCD4-Invert coupling cup also contributes more than their original coupling cup. So vibrations being drained seem to be important to sound also. One hears about mechanical coupling and the speed of these devises in getting vibrations to the floor and earth. 

I knew about magnetic waves derived from a signal going through a wire, so I can see how vibrations can induce signal in one preamp, amp, and other components. But why does the speed of draining the internal vibrations help versus devices that turn vibrations into heat work?

I long ago gave up on total harmonic distortion as a measure of the quality of an amp, when it proved unrelated to what I heard. One can measure it but if it is unrelated to the quality of music reproduction, who cares?
