This is a very interesting article on spiral shields.

I must say that after drinking the exotic cable claimed performance kool laid for years, I finally woke up about two years ago.  Now, my speaker cables is made out of the Lowes 6 gauge THHN wires and the ICs are home made Belden 8422.

That is interesting.  Never used these for video, but they are the best I have ever used for audio.  Period.

"The net effect is that the shield transfer impedance increases with frequency above about 1 MHz"

That would be MegaHertz, not the 20kHz ceiling for redbook audio and 100kHz claimed for SACD.  This would have no consequence for audio use, though I wouldn't use it for video use myself.  

I am a bit surprised to see the inside of the Audience component video cable.  It is probably same as their AU24 audio interconnect, just rebadged for video use.  $500 plus for 1m pair of audio interconnects made of their magical OHNO copper, bit of polypropylene, copper spiral shield...

It is the same.  I broke a spade off my speaker cable, and it's the same as well.

If you are having cable custom made to your specifications it is cheaper to buy 25,000ft. at time all the same formula than to buy three different designs of 10,000 ft. each. The only potential problem comes when your speaker wire winds up being a smaller total guage than desirable or your shielding design is inappropriate for the intended application.  Economic compromises rather than sonics are frequently a major determining factor in what cable a company brings to market,particularly a small  company just getting started.

The problem is you do want the shield to remain effective above the signal band. That is within the range of the interference to be sheilded!

It seems this cable's success is the result of the HOM design principle, "hit or miss".
