Out of all the ridiculous things, this one is actually not completely ridiculous. For low temperature physics applications, Oxygen-Free High Conductivity (OFHC) Copper is the only material that is sufficiently thermally conductive at low temperatures. I’m not an audio person, but I have a hard time imagining it would make much of a difference at room temperature; maybe similar performance with a slightly thinner cable?

Avoiding corrosion may be another benefit, although I'm not sure how much effect it has in practice compared to regular non-oxygen-free copper.

Finely stranded, tinned copper marine wire would be the ideal for corrosion resistance.

My walk in freezer sounds amazing though
