Why "Cryo" anything?


Ok. So far, I have yet to think of a good explanation for "Cryo" treatment to enhance anything. Can someone explain this to me?

For background, I have a Master degree in Material Science Engineering. Here is my explaination why just "cryo" won't work.

At room temperature, the metal is already solid or frozen. Freezing it further won't do much. Most metals requires high temperature to cause any change in the microstructure or grain size/orientation/distribution. Simply freezing it for a few minutes will not change how it operates after the metal returns to room temperature.

"Cryo treatments absolutely do great things sonically for many (not all) audio pieces (results based on double blind studies)."

Now this is what I'm looking for! As I've said, I don't do the cryo 'cause I haven't been able to find any real published DBT results that showed any improvement, much less consistently identifyable improvement. Hopefully we can (finally!) start to get some resolution on this.

Larry/Cello - now you've just gotta post links or references to these double blind test studies, oh please, please, please? Pretty please???
Sorry, Newbee - apparently someone got up on the wrong side of the bed today? I read your post and didn't find anything all that inflamatory in there...

I also read quite a bit of the CryogenicsInternational stuff. I found it mildly interesting, nothing I hadn't read/heard elsewhere, and mostly marketing - this is what they sell. Not that it's wrong, just consider the source.

And you know what? I have absolutely no problem with cryogenic treatment of materials for mechanical purposes. It's fairly well documented that quenching, cryo-ing, whatever can affect certain properties of metals, etc. Those things are all objectively measurable and testable and repeatable. No problemo!

And you know what, #2? I have no problem with cryo-ing audio gear, either. Have a ball! If it's what you want to do, if you think it works for you, if it doesn't hurt anyone else, if you don't ram it down their throats (and they behave in an equally civil manner) then no problemo!

I don't cryo - yet. I have not been able to find any double blind testing that shows a difference, and until then it's just not worth my money. And no, just trying it and "do I hear a difference" doesn't really cut it, either. I know how susceptible I am to suggestion (heck, I'm married - that pretty much shows how easily I can be had!). I know I'm getting older and my ears probably aren't worth squat, so if someone can't measure an objective and repeatable improvement then I'll save my money for other goodies.

No problemo!

PS - one confession, though. Cryo-ing CDs just makes me scratch my little pea (pee?) brain. I've really gotta work to keep the pod open on this one...
