Somehow I could not access the site since composing a couple of replies, until now....
If there was an exacting answer, all cables would be made to one single exacting standard and there would not be any cable wars.
It isn't about cable wars, that's just a by-product: it is about a whole market, based on supposition, half-truths, pseudo-science and downright lies --- with, probably, a massive amount of overcharging (and nice fat dealer margins) liberally sprinkled.
The dealers may say that their margins on electronics are too small and get squeezed even smaller. I don't really blame them for wanting, even needing, to make a buck where they can, even though it means signing up to this whole charade.
It doesn't matter if the product is genuine: it is still marketed by the means I have mentioned. The strange thing is that ours is a
technical hobby, and one would suppose that the buyers would be technically minded, and not prone to technical bullshit --- but somehow, the chocolate box has been so well presented, that mouths are made to water by everything from OFC, through teflon, silver and other exotic ingredients, all the way to oak collars, not to mention a superb physical presentation. Is there such a thing as the skin effect? Of course: remember the saying:
beauty is skin deep!
Almost (I admit, not all) the engineering/technical/scientific commentators simply try to shoot this stuff in the knees, but it just refuses to fall over. In most commercial areas, if something is shown (or even alleged) to be, at least to some degree even if it is only in overcharging, a scam, the market collapses. Not this one. The
buyers want it too much.

There
is an exacting answer, and that is the reason why pro audio does not suffer from this stuff. Of course, even there there is a range of pricing (but no really silly numbers, even for the best stuff). Even pros have their quirks, and they have to market their services to their customers, so yes, you will be able find studios that
advertise that they use some sort of cable with a name that might be recognised by audiophiles.
So why is there a price range even in pro cables? I don't have to tell you where

So if Materials don't Make the Difference, What Does?
All right--if fancy and expensive materials aren't what distinguish bad cable from good cable, what does make the difference? The answer is that cable manufacture is all about consistency and tolerances. Is that surprising? Consider that all automobiles are made out of basically the same raw materials--mostly steel and plastics. The difference between a Yugo and a Ferrari has a lot more to do with what one does with the steel and plastic than with how good the raw steel and plastic were before anyone made them into engines, components, and body panels. With cable, it's all about controlling dimensions and consistencies. How consistent is the size of a wire from point to point? Are the nitrogen bubbles in the foamed dielectric of even size and distribution? Is the outer dimension of the dielectric different from point to point? Is the tightness of the foil and braid the same from point to point? The electrical characteristics of cable are intimately bound up with these fiddly little questions of controlling manufacturing tolerances. Somewhere, someone is scratching his head right now over just how to center a wire inside an extruded dielectric just a little bit better--perhaps by a ten-thousandth of an inch--than is currently possible. Questions like that, for those who don't need to deal with them for a living, are exquisitely boring. But attention to these questions is what makes the difference between American broadcast-quality cable and the cheap Chinese stuff which is so very common on the consumer audio/video market.
In Conclusion...
Fine materials and quality manufacturing practices make the best cables; but the best materials for cable manufacture aren't always the most exotic or fancy-sounding. Not only are quality copper wire and nitrogen-injected PE foam dielectric great materials for building a precision video cable, but manufacturers like Belden make the best use of these excellent materials by employing them in well-engineered manufacturing processes, with tight tolerances. The result: cables of the highest quality, relied upon worldwide by professional broadcast engineers when the quality of the signal is of the utmost importance.
Consistency... Hmmm... Anybody ever draw down wire? I have. I imagine that doing it with a big machine only deals with part of the problem.
PS... I got my cables. They arrived before I even got around to checking the FedEx site! All the way from Delhi on a ground-speed-record-breaking jet propelled Piaggio Ape. The driver was a bit dusty, but the cables were fine.
