Cryogenics: accomplish what and work how?

I've used cryo cables and found little difference. Keep in mind, it is difficult to compare the same cable cryo vs non-cryo. Either a manufacturer does cryo right, or not at all. So an apples to apples comparison is nearly impossible. That said, you should take my "little difference" with a grain of salt. However, I have tried the same tubes (NOS) cryo and non-cryo. There is a substantial difference here. Lower noise floor and I believe longer tube life (but really can't be sure). I can say I was impressed with the dramatical difference. Tubes are such sensitive devices that it does make logical and physical sense that cryo treating would have a beneficial effect.

thanks. i'm going to take these answers down to the materials science lab in the office below mine and see what they say. most of their work is in alloy extrusion. they may be able to treat some cables for me so i can make a direct comparision. i'll let you know what i hear.

I can understand the changes to the wire portion of the cables. Should I assume that an already manufactured cable (with insulation and jacket) cannot be treated?

I don't understand who cryogenics can improve a CD at all, since there are "one pits" and "zero pits" on the disk, how can it improve these pits?

Unrelated- I use croyed razor blades. The shave and durability is incredible. Each mach 3 blade lasts 4-5 weeks of daily shaves:) And we all know music sounds better with a clean shave.!

As an easy, poor man's experiment, consider trying this: put some of your interconnects, power cords, and CDs into sealable plastic bags. Pop them into the freezer for about eight hours. Then put the bags into the refrigerator for about the same amount of time. (The trick is to have a slow warm up.) Then let the bags sit in a cool spot in your room for three or four hours, or until you're fairly sure they're at room temperature.

I find the improvement quite surprising and it seems to be permanent. I'm not suggesting that this is a replacement for "deep, computer controlled cryo", but at least to my ears it's pretty effective and the cost factor can't be beat.
