Cryongenically treated in-wall AC power wire

Not to mention the directionality of the power cord. That’s why Audioquest controls directionality for their power cords, as well as all of their other cables. So unless you can verify which direction the wire in the DIY power cord is supposed to go, cryo might not make any difference or may allow you to hear how the wrong direction affects the sound. There’s also the issue of thermal shock when cryoing cables that means judgements should be postponed at least a week after getting the cables back from the lab.

There have been some credible reports over the years from people saying they don’t like the sound of cryo. On the other hand, a great many more have reported they DO like the sound of cryo. So, it’s not like the issue is split 50/50%. Thus, it’s probably best to describe cryo as another one of those he said she said type situations. Michael Green is very experienced so his testimony can’t be easily discounted. There are some technical arguments why both heat AND cryo solutions might work, sound wise. Certainly the cryo process can temporarily make things sound bad/funky (i.e., thermal shock) so that in itself might explain some of the negative reports. But maybe not all.

It would be a Big Shame if cryo does turn out to be bad for the sound, makes the soundstage disappear or whatever, which I doubt, since so many cable manufacturers have been turning out cryo’s cables for years, not to mention high end electronics companies like Meitner have been routinely employing cryo for years. So, obviously there will be a whole lot of very Unhappy Campers 😢 out there if this cryo thing turns out to be hoax, which I doubt it will. I wouldn’t bet the ranch however.

Cryogenics is the portal to the really advanced stuff which unfortunately I can’t talk about here. Maybe in the future. You know, the unspeakable.
