While I believe that cables matter, skin effect is the biggest piece of hogwash ever.
A more likely explanation for cables sounding different, based on what I've heard, is that the amp and speakers are more sensitive to the miniscule LC and R values than the math would have us believe. Perhaps feedback also plays some role here, but 100% of every cable effect I've ever heard can be explained purely in the frequency domain. Oversensitivity to basic cable measurements could explain it.
Also, most cables are way pricier than the apparent changes they produce.
