Cryogenic experience wanted. Constructive please


I have been saving and working to upgrade my system and its been paying off. I'm finding listening to small changes assessing then going back or moving forward, largely paying attention to tone ( probably harmonics really) does it sound more like a violin etc. Also paying close attention to feeling of music ( does the change bring me more involvement with the content) have been reading about cryogenic treating speaker driver. Could anyone share some insight to who, where, what; or what not to treat. My drivers are Omega 8" alnico with hemp paper I believe. Is there a large risk in treating them. I mean physical damage not how they will sound. What would those of you who have done treatment to gear suggest doing cables and tubes even component all at the same time? Thanks for reading all that and any input is appreciated. Please no, does it work or how. If you have not had items treated and want to talk hype. Please refrain thx.

My experience is pretty much the opposite of Peter's above for what it's worth.

I've cryoed entire components, but mostly very cheap units as "experiments". Results were mixed: one DVD player seemed to benefit much more from treatment than another, but both were very cheap players and are no longer around.

There's also much more potential for damage with thermal shock with entire components due to the much larger numbers of dissimilar materials.

I would highly recommend treatment of all cables (power, IC and speaker) and receptacles with one caveat. If you are going to treat all cabling at once, I would strongly suggest you seek out some kind of cable cooking device like the Audiodharma or Nordost and have everything burned in post cryo.

If you don't be prepared for a fairly lengthy and nasty burn-in process that may take as much as 30-45 days and with all cabling done at once and reinserted into a system, the cumulative effects of cryo without burn-in will be quite nasty.

Receptacles may be burned in on something like the Audiodharma; alternatively, two or three weeks on a household appliance with a strong current draw, particularly with a compressor that kicks in like a refrigerator or chest freezer, using both halves of the receptacle, should get you most of the way there.

In my experience, movement or bending of the cables has not diminished the effects of cryo (I've had every receptacle that my system draws from, including those in my line conditioner, as well as every cable in the system treated and most have been in use since treatment for 7-10 years plus), nor should it. All scientific evidence points to a molecular change that is permanent.
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,
