I'm an electronics technician, not an engineer. But I do work with some engineers. I brought some ads from some audio magazines to them, and let them look at some for some interconnects and power cords. They were all astounded that anyone could possibly believe this nonsense. The characteristics of any wire can be measured, and in fact has to be for industrial use. The right wire is critical for industrial applications. But what blew them away was a power cord that cost almost a grand, that could be gotten from digi-key for $3. Perhaps Penn & Teller should do a show about this stuff.
