That was a fascinating video. It's hard for me to comprehend the amount of engineering and execution that Apple has put into a $130 cable. It makes the long video Cardas produced to show how they produce their speaker cable, seem somewhat unimpressive now. IMHO
Interesting video on cables
At the risk of opening up this can of worms again, my brother sent me this video. It’s incredibly interesting and goes some way to showing why cables matter and that all cables are not equal. These are USB cables but I’m sure the principle applies to speaker and IC cabling.
