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

The Mach One speed is of course the velocity of the "wave" part of the sound wave.The details of each sound object is embedded in the instantaneous pressure which is seen on the vertical axis. The frequencies contained in the rich harmonic structure of each instrument is totally dependent on the delivery speed as being constant (seen on the horizontal axis as time domain). If the velocity slows down or speeds up then each and all instruments are shifted up or down the spectrum together by an amount of offset that stands out to the ear-brain system as "not real".
The entire performance has acoustic relativity - meaning if one instrument drifts in location, they are all drifting together.

It does by the way shift up and down the spectrum. This is how energy from the fundamental input signal appears (as distortion) a full octave away as the first harmonic.

My process does not have the problem of shifting anywhere because it is fully locked by the shift countermeasures implemented as nano-degrees of phase shift. It has a capture range of 0.07 nano volts max deviation.

It therefore has no mechanism in place to produce harmonic distortion.

Mapman, the speakers cannot reproduce the sound waves you would have heard had you been at the recording sessions if some frequencies get to the drivers before others.

With the H-Cat X-10 MkIII, this cannot happen.

Well why doesn't roger just say that then.  It at least makes sense and is understandable.  

This gear (H-Cat) was discussed at length years ago and there were many concerns around the company and very few found the gear to live up to what was advertised. Sounds like just more rhetoric to me.  

 

That’s very unusual, to refer to the speed of sound waves in the room as Mach 1, since Mach number is a dimensionless quantity, whereas the speed of sound has dimensions ft/second. Ordinarily we see Mach number associated with aircraft or spacecraft traveling through air at certain altitudes and temperatures. The SR-71 was a Mach 2+ aircraft! for example. The sonic boom of a jet aircraft is produced when air flow collapses around the rear of the compressible fluid of air at Mach 1. Mach 1 is not a constant and depends largely on temperature.
