I love it when this debate comes up again and again...
It's the same old story as far as I'm concerned, people pay and will continue to pay big bucks for quality speaker cables where the majority of the cost is for the name.
Does Monster ( and other specialty co's ) make cable that works well - YES
Do you pay a major premium for the name on the cable - YES
Once physics enters the equation the playing field get a lot more level. Regardless of who makes the cables, if they use good quality materials and have decent quality control the end result will be the same. It doesn't matter what a company claims to do during their "special" manufacturing process, they can't alter the laws of physics...
Would I spend $180 bucks for a 10' pair of cables - NO, not when I can get the same quality ( using applied physics ) from another manufacturer for $25 or less...
That's my opinion, not yours...
