Cryo'ed LP's

I had Cryogenics International in Scottsdale cryo many interconnects, CDs, and yes, some LP's. Leave the cardboard covers home and cryo only with sleeve on. There is no moisture, so sleeve won't stick. Cables did take a time to break in again but were quieter. The biggest improvement came from the CD's. Try a listening test with a treated and untreated CD of the same; the treated has a lower noise floor and will sound smoother. I was told the improvement was due to removing imperfections in the aluminum disc and plastic it is sealed in that prevents the player going into error correction often. I also felt the LP' s I did were quieter but the difference was subtle compared to the CD's. Long story short is it can't hurt the record and doesn't warp it. I need to treat my tubes; it is excellent for them.
