Cryogenically treated cables

Look right over your eyebrows. 

There have been papers, by real scientist (no for real), that have shown a several percent increase in conductivity in copper conductivity at room temperature after cryogenic treatment. What I don't remember (was a while ago), was what the initial purity of the copper was. I would not be surprised if the results are dependent on copper purity, hence if you are starting pure, there may be virtually no change. No indication this had any affect at all on high frequency, or any other useful property.

"...the electrical activity in copper when brought back to room temp will not be any better than with no treatment."

Finally! Thank you!

I have been trying to gently imply that warming it up may negate any possible benefit from cooling but to no avail.

atdavid, eeyeah, my post was for those who were addressing the OP in one manner or the other. Perhaps you should read it again to better understand it. And feel free to call yourself an idiot anytime. No argument from me.

Geez, even a tiny little fuse sounds better after cryo. Cut me some slack, Jack! We don’t need a doctorate dissertation to tell us cryo is good for any type of wire. Cryo makes things perform better. I wish I could tell you, gentle readers, how many things improve the sound after they’re cryo’d. Unfortunately, it gets into areas I fear are beyond scope and might be a little bit too much for the naive and those just starting out. 😳 I certainly don’t wish to frighten or snow anyone. None of this stuff is in books. Hel-loo! That’s why the -10 F home freezer is way more mysterious than - 300 cryogenics.

Don’t steal, don’t lift
Twenty years of schoolin’
And they put you on the day shift
Look out kid
They keep it all hid
Better jump down a manhole
Light yourself a candle
Don’t wear sandals
Try to avoid the scandals
Don’t want to be a bum
You better chew gum
The pump don’t work
’Cause the vandals took the handles

"I wish I could tell you, gentle readers, how many things improve the sound after they’re cryo’d."

I will help you.

It is only one. Ice-cream. And that one is not about sound but overall.
