Porcupine Quills?

-->"The directionality in wire apparently results from the deliberate distortion of the crystal grain structure during manufacture, wire drawn through die. The wire is compressed going through the die forcing the metal crystal structure to bend backwards in the opposite direction from the direction of the drawing, like porcupine quills. It's this *physical asymmetry* of the wire (all wire) that produces the "directionality."<--

I've never seen hookup wire that's labelled for directionality. So in a point to point wired amp or preamp wouldn't it seem to be a pretty safe bet that at least half the wire is installed backwards?

What about traces on a circuit board? If they are not drawn through a die I suppose that would mean that they are non-directional. Would you then expect that gear constructed using circuit boards would consistently sound superior to anything wired point to point if the same circuit and parts were used?

What about the wire inside a speaker cabinet? Or the wire in a speaker's voice coil? Or, for that matter, the wire inside a power or output transformer?

If my system doesn't sound quite right should I complain to the power company and suggest that some of their lines are installed in the wrong direction? What about your house wiring? Have you checked it?

What would it take to check to make sure that the "porcupine quills" were not facing the wrong direction? An electron microscope?

Given all the places where a large percentage of the existing wire is likely installed backwards, how much of this handicap can be overcome simply by installing the speaker wire correctly?
