Re: What exactly does cryogenic treatment do?

More helpful responses could have been posted. Since I'm a dealer for Acme Audio and stock the cryo'd outlets, you can take what I say with a grain of salt, or several grains, as you wish.

Liquid nitrogen used in deep cryogenic treatment slowly cools the items being treated down to about -320 F, or about -195 C. The nitrogen never comes in direct contact with the items being treated. The entire process is computer controlled, with temperature ramp down, temperature hold, and temperature ramp up. Depending upon the materials being treated and other factors such as thickness and dissimilar material junctions if any, the rates of cool down and warm up are adjusted. Typically the entire process takes two or three days.

Benefits of cryogenic treatment in terms of audio can include better focus and lower noise. Some materials are better suited to treatment than others. Bob Crump, whose products I also sell, didn't care for a pair of his TG Audio speaker cables which use silver wire that had been cryo'd, that it took away a lot of the natural decay of the notes, among other differences. In the case of Acme Audio outlets, the cryo treatment is generally preferred, not only because of the above mentioned benefits but also because break in (which takes 30 days) is smoother.

I hope this is helpful rather than sounding like a pitch. If you have further questions, please post away and I'll do my best to answer them.
