It's about speaker cables and how many bullshit products there are out there. I totally agree with the author.
Personally I'm using Supra Classic 4.0 speaker cables, but I got them for free when buying an amplifier and they are flexible and nice to use so that's why I'm still using them. I have compared them to some expensive Van Den Hul cables (borrowed from a hifi store) and some CAT5-cable. I didn't hear any difference between any of them, to be honest.
