Murray, just to start,

The skin effect is demonstrably insignificant, see the reference above, and 'non-linear inter-strand conduction' is undefined but it sounds good in a typical cable bollocks sort of way.

But how you get from the value of this piece of writing to the value of his 'QC/measurement system' is obscure. I assume he is catering for his target markets in both cases.

As I said I'm more interested in the results of the blind listening test.
