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

I'm was honestly trying to be just a "fly-on-the-wall" here.

I had an opportunity just now to read the white paper. Among other things I could disagree with, one in particular is the assertion that "air medium has no obstacles". Perhaps I am misunderstanding the context or usage, but since we are already splitting hairs, what about the micro-climate (i.e. variable temperature change) that exists in air between the orchestra and listener? What about other sounds ( a person sneezing) that occur or physical "occupation of space" such as a person rising out of their seat? Is that distorting the wave object?

On to the electrical end, is the wave object really effected all that much in today's modern equipment? And if it can be successfully argued that yes, it is, will "correcting" it make any - even the slightest - difference? If yes to that, then what happens when the two speakers (assuming two channels) are not precisely (as in less than 1000th of an inch) aligned and distanced from the listeners ears? Is distortion re-introduced?

I don't think any distortion would be introduced but one might hear it less precise in location.

One more question: once the signal leaves the amplifier it still needs to get to the speakers.  The speaker cables introduce additional velocity differences in the signal since the high frequencies travel closer to the surface of the conductor where the resistance is less, no?

It seems that the worst offender of the velocity errors is the power amp.
It may be because it has the task of converting the electrical wave into an acoustic wave via the transducers (speakers).

As you may know sometimes the IC connections can become "dirty" or poor and when you reconnect them or clean them up it restores the transparency and focus to your presentation.

That is the result of fixing a "poor" connection. The destructive nature of the poor connection represents a non-linear event in the chain. It does not take much of a non-linearity to scramble location information, etc.

By having a power amp that does not contain a non-linear path it keeps the purity of the chain much higher and allows the positive and negative wave-fronts to stay registered. (needed if you hope to hear live).

Let’s take a look for a moment at what kind of errors you’re actually talking about here. We know that the velocity of the audio signal in copper wire is some high percentage of the speed of light, 186,000 miles per second. Let’s say for argument’s sake the frequency with the highest velocity travels at 75% of the speed of light, or 139,500 miles per second. Now, suppose there are differences in velocities depending on frequency. How much different are the velocities? 5%? 10% 30%? Let’s take the largest number for the sake of argument. Thus, 70% of 3/4 of the speed of light is the velocity of the slowest frequency within the audio signal. That's our assumption. Which happens to be actually another big number. A huge number, in fact.  98,000 miles per second. Anyone care to take a guess how long it takes a signal traveling at 98,000 miles per second to traverse the circuits in an amplifier? Compared to say room anomalies and phase errors produced by speaker crossovers and differences in velocities inside the amp seem extremely inconsequential, if I can be so bold. Of course, you might be correct and your amp might be the biggest thing since Skippy Chunky Peanut Butter. It’s just not obvious why.
