Where does this information come from?

[E-Stat]

What places him with the scientific/objectivist crowd (aside from all the stuff at the end) is his statements that:

Lowering resistance of wire can done by increasing the gauge of cheap wire
instead of buying wire made from more expensive materials.

Beyond a certain amount of resistence reduction, there is no audible
difference in sound.

However, he appears to provide the subjectivist/observationalist crowd with some justification for their views with his points that:

The impedance of most speaker systems is not constant with frequency.

Systems with different impedance fluctuations require wire with different resistance.

High-end equipment can have impedance values that vary considerably from the
norm (such as the 4 ohm speaker he mentioned).

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.

Most average systems would not gain benefits from expensive wiring because the amps and speakers run impedance ranges that lie within more standard norms for typical consumer electrical equipment.

Agreed. 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.
