Cryogenic experience wanted. Constructive please

The cryo process strengthens materials, especially metals, and in the case of cables and internal wiring makes them better conductors. Cryo improves the performance of transistors, electron tubes, metal connectors, etc. The only caveat with cryo is that it is prudent to wait a week or so after receiving items back from cryo before critical listening as they can tend to sound a little strange until the thermal shock effects wear off. The cryo process is irreversible. Thank goodness for that.

Don't cryo a laser or electrolytic caps or speaker drivers. You could cryo the magnet assembly of a tweeter whose dome and faceplate can be removed. Tom

Did some investigation regarding the permanent effects of cryogenic treatment of wires, and it is a almost permanent effect. The wire will change slightly from bending it but not change back to its original form. This according to a few local treatment facilities. Guess Ill have to partially eat my words.

As Always, Good Listening

I don't think paper, pulp, hemp and the like are good candidates for cyro treatment. I could be wrong but from what I've read, metal benefits from it greatly as NASA, the DOD and scores of universities have found out.

I just read that the procedure lessens the repulsion side and strengthens the attraction side of the equation: a changing of their natural nature. It's a good thing for metal since the crystal nature of metal with a greater attraction will hold together tighter, allowing a freer flow of electromagnetic waves. This tightness lessens the "Josephine's Junctions" which interrupt that flow.

I don't think one would want these properties applied to a speaker cone designed to move in and out, get looser from break in, and achieving a final state of elastic play.

I just read this and may be all wet on the matter but it's food for thought. Others here who know more will eventually offer more authoritative advice.

All the best,

There are variables such as time to reach cryo temp, length of time at cryo temp, actual cryo temp and time to return to ambient temp. I believe these variables can affect the end result.

I would seek info from someone who is knowledgeable and experienced with the process because I think it's more complicated than just randomly putting something into "cryo".
