Sounds to me that the comments are all over the map. It's clear to me there are variables that the DIY's aren't considering and even some that cable companies aren't considering as well. When I was a consultant I evaluated some very expensive cables and inexpensive ones from various manufacturers. I came to the conclusion that cables make a difference, the differences have nothing to do with price, and some high end manufacturers either ignore EMI or they don't know how to shield their cable from it. You guys have the right idea here: buy it, listen to it, and take it back if you don't feel the improvement is worth the $ or if it's worse than what you had originally.
