John, it's true that silver has the best electrical conductivity of the metals, but copper is second and as the table
here shows, the difference is negligible in comparison to other metals. A 25 foot copper wire would have the same resistance as about a 27 foot silver wire. Copper is a nearly ideal relatively low cost electrical conductor, so silver wire makes no sense for home audio. Cryogenic treatment is pure hogwash. Incidentally, since the topic has come up, my undergraduate degree is a B.S. in Chemistry, although these days anything much more complicated than H3 O(or whatever they call that stuff)is beyond me. Still, I had enough of the scientific method pounded into me to be able to recognize and not be able to tolerate the charlatans in audio who prey on the gullible.
