Another Cryogenic Freeze Article HFNRR


Latest issue of British HiFi News Record Review has multi page article about deep cryogenic freezing of cables. Author
teams up with Townshend Audio (which sells cables) and take a batch of copper wire, deep freeze it, and then assemble various cables from it. Author was able then to compare
stock TA cables to deep freeze cables, to make a long story short he likes the deep freeze effect, and TA plans to market line of cables with cyrogenic treatment.

Mr Meitner, long time cryo advocate, also is given a page to
give his endorsement to cryo treatment.

This topic has been covered many times here and in previous articles elsewhere, I wonder why no cable company is actively marketing cables with this treatment? Some companies like Harmonic tech and Acoustic Zen use a process that modifies crystal structure of copper, but no one I know is marketing cryo treated cables.

Although many say it works, I personally am afraid to use this tweak, because it can't be undone/removed. Why are
the tweak happy cable guys not marketing this?

I have done the cryo freeze with my AQ Diamond X3 and Diamond Extreme. Made the cables sound smoother with more "air and space". I used Liquid Nitrogen.....
In response to Megasam:

I used to work with Liquid Nitrogen as a part of my experimentation at work. Since then I have changed jobs and no longer have access to the Nitrogen.

As far as the procedure, it wasn't very scientific...
Chill down was achieved by blowing the liquid into an insulated dewar with the cables inside - Immediate Chill. Being careful not to bump the dewar at any time, I left the nitrogen evaporate off for a period that took almost 24 hours. The cables came to room temperature on their own in the next 24 hours without touching the container they were in. FYI - the cables were suspended horizontally (straight) in the liquid on teflon blocks.

The system seemed to sound smoother and presentation with more air. No other side effects were noticed from the deep freeze.

Hope this helps... and good luck.
Long term effects?? Haven't noticed any in my cables... They still work well (sound great). Never tried tubes -- scared to break the glass with the chill.

In theory, the cryo freeze should not "wear off" -- the process is supposed to compress the grains in the metal more tightly..

Voodoo?? Maybe...
