Re: What is cryogenic treatment

Cryogenics is the freezing of objects to absolute zero and slowly allowing them to warm back to room temperature. This process is done with musical instruments, particularly brass instruments, and is said to give greater ease to the sound.

The theory is that freezing to absolute zero [with liquid nitrogen commonly] brings the molecules of the object to there lowest potential energy states. Anything that is formed by heat, as metal working is done is exposed to high heat and rapidly cooled. This leaves the molecular structure at its highest energy state and will sound more stressed than a cryogenically treated instrument.

I'm not aware of who is cryogenically treating cables, but some audio manufactures have used this process, I believe Vans Evers uses it on some of his power conditioners.

The question is does it have a positive effect, and I believe the answer to that is yes it does. How much are people willing to pay for it's positve effects is the question. Treating a small horn like a trumpet could costs a couple hundred dollars, but to a professional this would not be outrageous. I've even heard of people cryogenically treating CDs and have found a definate improvement, less "digital" sounding. Anything metal could benefit from this process, so speaker cables and interconnects would be as good candidates as any.
