Cryogenically treated cables

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.

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!!

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.

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!

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).
