Ejliu,
I would think cryo treatment comprises a complete cooling and (re)heating cycle; i.e., the return to room temperature constitutes "heating" in my book. No heating above room temp is required, but I suppose it could be used along w/ cryo in some applications like hardening of tools, etc.
Cold tempering (as I use the term) has been around for a very long time; what is in vogue, as you say, in audio is same process (or should be) as Cryopro and other outfits have been doing for years. Actually cryoing has been around in audio for quite, more than 6 or 7 years, now that I think about it, Meitner, Walker, and many others, some more public than others. I first started using Crypro about 12 years ago, about the time that some big guns like Holleywell were experimenting with cryoing transistors. (Never did hear about their results heheh)
