I share your opinion of "high end" audio cables, but nobody else hear was talking about audio or making claims of skin effect at audio frequencies.
My point was that even though audio (generally up to 20Khz) is much higher in frequency than what we are talking about here, the skin effect is not even a consideration. So why would it be at 60Hz? It's also easier to find information about skin effect as it relates to audio cables than power cables.
