I once had a girlfriend that had been cryo treated but she never thawed out! |
Has anyone noticed whether or not the color of the mesh or outer covering of their interconnects changes after cryo treating? |
had some ic's cryo'd by jennifer at jena labs.
AQ lapis X3 showed inprovements, like getting a few more horsepower for very inexpensive investment.
not sure i'd give my audiotruth or other to a machine shop to treat with cranks and cams. |
While we're talking about freezing cables, has anyone tried the cable cookers available? For that matter, has anyone tried sautéing their cables? With butter? Margerine? |
We used to treat aerospace components cryogenically to increase their stability to change dimension in space enviroments. We are talking of millionths of an inch changes. We had to use 20 hours soaks in liquid nitrogen to do the job. Dry ice and freezers were of no use. I would assume that changes to the crystall structure would need such treatment for cables. It sounds like a scam to me. |
from what i gather, you could get all the benefits of cryo via an extensive break-in w/ a specialized device (a MOBIE, for ex).
cryo is NOT simple. you cannot just drop your wires into liquid N and expect them to emerge better---proper treatment required gradual reduction & increase in temp over a long period of time (a few days ideally). a real cryo shop will know how to (see Controlled thermal processing in Chicago).
i cryo'd my silver ICs---took all brightness out of them and made them very enjoyable. a MOBIE did roughly the same thing. which is better? don't know, as i used diff formulas (but used silver on both, and Ag is always bright until broken in).
also see secondbeat.com for a recent AB blind test using cryo.

Go read a metallurgy book, guys!
Bringing an industrial knife from (-320) degrees F over a period of two to three weeks to ambient temperature after being tempered is NOT cheap.
And stop listening to cables, will you? It's a new year! |
Here is the statement made by Jena Labs regarding Dry Ice: Several audio writers, equipment modifiers, and so-called technologists have promoted refrigeration of cables and electronic parts by packing in Dry Ice. This is NOT cryogenic treatment. It results in only minor and temporary improvement. Even gas bath refrigeration in a cold furnace cooled by LN2 will not provide a sufficient chill. Scientifically speaking, Cryogenics refer ONLY to temperatures at or below the vapor point on Nitrogen, -320.4° Fahrenheit. Our process involves temperatures that are substantially colder than this. Clearly, dry ice has nothing to do with Cryogenics. Only true Liquid Nitrogen Immersion, as employed by JENA LABS will fully and permanently enhance the musical behavior of metallic conductors. |
I think it's Jena Labs which really bags on using Dry Ice as a means to cryo treat cables saying, "the effects are only temporary".
I seem to remember a post on Audiogon about someone who put cables in the freezer...they got moldy and crusty or something. Ick! And to his amazement, they also sounded terrible!! |
Stan Warren uses dry ice for all his mods and cables. He did tests with friends at a university in Oregon that had access to frozen nitrogen and they concluded dry ice is cold enough. So you can do it at home. If you call Stan Warren, I am sure he would tell you how he does it. His number is available on other threads. |
While I haven't had ANYTHING Cryo-treated myself, I have noticed an alarmingly significant increase in the number of "cryo-treated" used cables for sale on Audiogon - but were not advertised as such.
While there are many folks who suggest that cryo treating cables is the best thing since sliced bread, I would presume that most of us who buy used cables often, would like to know the truth behind the history of the cables.
From what I have read, CT works well on some items - but can destroy others.
For those who read this - please remember to ask the seller before buying used cables (and other components) whether or not the item for sale has been treated. I'm sure you do not want be the sucker who spends hard earned cash for someone else's scientific experiment. As far as I am concerned, if a used cable has been cryo-treated, it is worthless on the regular used market.
For those of you who brave enough to have cryo treatments done, here is the name and number of a source.
CyroPro (888)300-2356 talk to Dave - I believe they charge 10 bucks a pound for the service. |
It doesn't cost very much to do cables. I bet you could get a dozen interconnects done for under $30. I talked to a place here in town (cedar rapids, iowa) about doing some parts for my drag bike. While I was there I asked him if he'd ever done any cables, he just looked at me kinda funny and said "I've never done that before, what's it supposed to do?" I told him what i've read about treating cables and he said to bring them in sometime and he'll run them thru the treatment for free if i'll give him feedback as to how well it worked. I haven't gotten around todoing it yet but when I do i'll be sure to let you guys know. |
So no one can give me a sonic description of before and after.
I know what the process does, but what effect does it have on the cable sonically.

Are you planning to cut some material with them? Cryogenic treatment is very expensive. It is used to bring metals to ambient temperature over a very gradual time span after tempering. This period could last sometimes weeks. The purpose is twofold: to keep the crystal lattice in the intended spatial arrangement and to avoid corrosion caused by tempering with salt. As an example, some high performance industrial knifes and other precision cutting tools (such as Japanese hairsculpting scissors) are now being cryogenically tempered.
It's a great buzzphrase for marketing!
Voodoo once more... |
evo: there is a wealth of knowledge available about cryogenic treatment of cables on this and other sites. for a starter, you might goto:
http://www.AudioAsylum.com/audio/cables/bbs.html
in the "text to find" box, type in "cryogenic." i'm sure you'll find something of interest.
happy freezin'
