Cryo Treating Silver Cables?

HiFi Tuning has had great success with cryo treated fuses made of pure silver.

I have two cryo treated silver cables -- one USB, one phono pair -- and I think they are very good-sounding. I can't say anything about the purity of the USB cable, made by Audiogoner Acreyes, but the phono cable, from Audio Sensibility in Toronto, is OCC silver FWIW.

Zmanastronomy: It might be more accurate to say that

Acme cryo'd silver fuse holders and cryo'd silver plated wall outlets have been around for a very long time. No mystery here.

Should I cryo the metal plate in my head, even though it is not silver? Any Ideas?

One idea is remove the plate, it might make you a little more "open minded". Worth a shot. :-)

I'm using a cryo'd Oyaide DB-510 (BNC terminations) and I can assure you that it sounds excellent. No problems to report!
This cable was cryo'd by the company (CryoParts) from which I purchased it.
Unfortunately the company no longer exists because of the death of its owner.

I used to cryo all sorts of things. No longer. Synergistic Research's Tesla coil zapping really works, but cyroing IMHO makes everything smooth and dull.
