Silver plated for reduced skin effect? Great for RF frequencies, but
kinda useless for audio, where the skin depth is about 8 mm at 100Hz.
I don't think anyone can afford 8mm of silver plating thickness.

I don't need a primer on the subject.
It has nothing to do with skin effect. Silver conducts better. D'oh!
The ohms per foot is lower. Lower is better in this realm.
The plating is micro-inches on top of a copper wire that's mils in
diameter. And silver conducts only a little better than copper. So the
net effect of silver plating on wire resistance is unmeasurable.
