Do Rolexes and Patek Phillipe watches make you sick too? Fancy cables, like luxury watches, are just functional jewelry. I don't own either (I wear an $9 plastic watch, when I wear one),but if people like fancy jewelry, I say: go for it. In the high tech industry, especially in the Bay Area, one easy way to get some guy from another company to like you is to complement his expensive watch, if he's wearing one. A lot of executives wear them. And you show serious interest when they tell you the story behind it. That strategy works every time.
The truth is that standard Blue Jeans cables are a bit of a luxury item too. You know as well as I do that Monoprice is just as technically good, but I like Blue Jeans termination quality and their awesome customer service. And I can afford to pay for it, so I do. I know you'll agree, some things are just worth paying for. But not that Iconoclast stuff; not for me. ;-)
