@jhills, "Not sure how gallium, indium and tin, a semi liquid goop, 1/15th the conductivity of oxygen free copper, is somehow superior to pure grade, oxygen free copper as a conductor for cables. I guess whatever makes a great sales pitch and you can stick the highest $$$ to.
While there are a lot of bogus claims of all kinds of miracle insulative coatings and shieldings for audio conductors, in reality, the best material, as an insulator for either data or audio signal conductors, is either PTFE (Teflon) or polyethylene, with as little shielding and protective covers as necessary, for a particular situation."
Thanks for putting it as clear as it possibly can be as of 2019.
Perhaps one day things might actually improve...
