Cryogenically treated cables

As the hillbilly said to the city slicker in Deliverance, you don’t know nothin. I don’t mean to pry but is your brain really the size of a pea?

I am a city slicker, I don’t know nothin about peas.

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.
