As expected, a cheap coat hanger makes for a speaker cable indistinguishable from a high-zoot Monster brand cable. At root, these are all simple electrical signals. We've known how to carry electrical signals efficiently for probably more than 150 years now. To wit: thicker cable, good copper. The rest is just marketing. Which is why I've never thought twice about using cheap, thick copper wire to connect my expensive components.

Don't even get me started about the guy who gave a positive review to a $230 power cable!
