Where does this information come from?

Despite all this fuss about resistance, it completely ignores what is likely the more important of the three primary wire criteria: inductance. My cables have about one-sixth the inductance of 12 gauge zip.

Certainly a valid consideration. It'd be interesting to ask Russell about that.

...Not to mention "average systems" are lower in resolution to warrant the effort. As with any piece of equipment, I believe it is all about matching electrical and performance capabilities.

Well said. I believe there'd be less arguing on the subject if everyone thought that way.
