I had a co-worker a few years ago, and we were charged with the responsibility of installing a flat screen display in the public waiting area of the premises. Came time to purchase a wall mount for the display, and my co-worker, who had previously worked in the audio-video dept. of a large box store said that wall-mounts were a very high profit item, and that he could use his contacts to get one for about 25% of the usual price, which he did. When I talked to him about this, he told me that such things as mounts, stands, CD holders and CABLES (HDMI, Speaker, interconnect) were also in the very high profit category.
Retailers push these products, including the "exotic" cables, because they make lots of money doing so.
Personal opinion: wire is wire. For speakers, as long as it is the correct gauge, and made out of copper, it will do the job, and there will be no difference in sound between that cable, and some exotic, high-profit product.
