Cryogenically treated cables

I am wondering if crying my 18 gauge zip cord would produce positive results. 

Cryogenically treating anything improves its performance. And someone recently posted, even putting cables in the home freezer for 48 hours offers a very noticeable improvement.

Ummmm......what???

Wow! Looks like there’s a fly in my spider web already! Breakfast! 🤗

Do a Google search on something along the lines of "electrical conductivity copper cryogenic treatment". After you sort through all the results on thermal conductivity and electrical conductivity at cryogenic temperatures, perhaps you will find a paper or two about measured effects ..... and pretty much anything left will be consumer audio cables.

Perhaps, at this point, you will ask yourself why, when cryogenic treatment is only modestly expensive, are there not more articles, advertisements, etc. about cryogenic treated copper for improving conductivity and transmission in industries where they can both justify the expense (i.e. communications networks) and where they have the knowledge, expertise and equipment to quantify the differences?

Teflon and similar fluoropolymers can withstand cryogenic temperatures fairly well. PVC jacketing, and even the very common polyethylene insulation essentially becomes glass like, so any movement can induce fractures.
