This e-mail has been cryogenically treated

@rodman99999 thank you for those links. My undergraduate degree in the dark ages of the early 1980s was in aerospace engineering but my first job was in designing tooling for turbine blades. I believe G.E. at the time did use cryogenically cooled tooling in some cases for the benefits it provided in longevity and dimensional stability.

But the question remains to ask an electrical engineer, or a physicist would be why changing the lattice structure of steel or copper to be different or more organized does anything beneficial for electricity flowing through it containing information that is modulated (for analog) or "offs and ons" (for PCM digital)?

I’ve seen the marketing claims, and I don’t deny that better constructed cables can sound better than poor ones and of course they can last much longer.

Yet, I’d like to understand what is it that you could measure objectively between two similar cables, one that is cryo treated and one that is not, and point to it saying, "there, that one will sound better"?

The other paper focuses on GaN based electric devices and lowering the resistance of their interfaces. They noted the cryo treatment helped if those connections were Nickel/Gold but that cryo treatment actually negatively impacted the resistance if those connections were Palladium/Gold.

Now, lowering resistance is generally always a good thing, and for the relatively new GaN devices very important for their operation. But once again, at the end of the day, is it audible in an average audiophile’s system and room?

I’d love to see some practical measurements and double-blind listening tests.

I’m not saying there aren’t differences, just that at some point, are we discussing how many angels can sit on the head of a pin relative to what we humans can hear?

@rodman99999 "BUT: there was still a contingent (like here, on AudiogoN), that wanted the universe (and electricity) to always make sense.    Of course, it's been widely/scientifically proven: it seldom does."

Yeah, there's "science", there's "math", and there's engineering, which is applied science.  Ever since Maxwell came up with his equations, Newton's laws, and Einstein's relativity, we struggle to make sense of it all, especially quantum mechanics.  But we engineers simply can use the equations to design things that work. We don't have to know "why" they work. LOL.  That gets into metaphysics and even religion, which is above my pay grade. 

All we know for sure is that our current understanding of the universe is very incomplete, but hey, we've only been seriously at this "science game" for a little over 400 years. In that context, it is amazing what we do know, or think we know.
