This XLO explanation is truely inventive. "Skin effect phase shift" and inductiveness of metal?
The inductance of cable is so low they are usually not even specified in cables. Usually the inductance are too low.
In telephone application, after a couple of Km, the high frequency are attenuated more than the low frequency. So loading coil (inductance) is added to reduce this attenuation (maybe a better word is equalize).
If you pass by a telephone pole next time, you can see a long metallic box in the middle of the cable and that's the loading coil.
Skin effect has to do with current density. It does not change the phase. In any case, if you see my calculation, skin effect is not going to do anything to the characteristic of the wire unless you're using 10 AWG or larger cable. I doubt anyone will be using interconnect that thick.
Also, we need to put things in perspective. We are dealing with less than 6 feet of wire not 1000 feet. IMO, under 10 meters most variance are too small to impact sound quality.
However, I do have cable that sound different. One time I pushed my amp to close to the wall and crimp the cable at the connector. And somehow it made a difference in the soundstage. I kept the cable as a demo. Still, most people don't notice the difference until I point out what to look for.
Another point, some time ago RIAA tried to use a low frequency beat as a watermark in the music to prevent copying. Because of all the audiophile's objection, they cancell that technology. I read that one Stereophile editor actually listened to the watermarked music and can't tell the difference. It wasn't until he was informed what to look for that he can tell the difference.
The brain can do some remarkable things.
