I must agree with some of your comments here. I think you can tell the difference between a $1 and a $350 cable. However, the value of diminishing returns kicks in rapidly has the more expensive the cables get. My best friend used to work for a company that manufactures cables for Cardas about 8 months ago. Cardas would send the connectors and her company would provide the cable and the assembly. Dealers charges about $750 per meter for golden cross. She told me that her company normally pays only $7 per meter (without connectors of course) and her company would then charges Cardas ~$21 a meter. If you do the math, that's a hell of a margin for Cardas. Bottom line is that cables do make a difference, but what I don't understand why is it that cable company decide to charge so much? $5000, $10,000, what's the basis for that? Perhaps cables is 10% science and 90% snake oil. As the some cable prices continue to sky rocket, wouldn't it be cheaper to go down to your local jewelery store and pick up a meter of 24 karat gold chain? Why have gold plated, when you can have the real thing! Just be sure to wrap your 24 karat gold chain in electrical tape so no one gets shock!
