RUR my experience of cryoing was during a period of roughly a yr when I was building ICs and power cords from scratch. I had some of these cryoed twice (based on the results of some on the web). I would cryo my present cables but the two plants that were accessible - couple of hrs drive that I could detour to, and at a v fair rate - unfortunately have ceased business, the remaining facility going to -90C deg only. NB I'm not given to dumping $s on something that doesn't provide benefit, and v aware of the argument whats your reference.
"I'm well familiar with cryo processes, applications and tangible benefits."
Please give some insight, especially in relation to audio products, if you are able to.
