I have some El Cheapo, wire connected to my rear speakers, because the aesthetic police (aka wife) wouldn't let me run heavy guage wire across the floor of the den. I've just read about this Nordost flat cable - which could be run under the carpet, and was wondering if anyone had opinions. Nordost makes some VERY expensive stuff, but I am only considering their two lowest price products: Nordost 2-flat, and Nordost Flatline Gold MKII. Are they OK? Should I go for the more expensive MKII? My runs will be about 25 feet.
