My post was meant to show this difference. Being a strong believer with a lesser sense of balance often leads to BS.
I do not doubt your technical skills.

I often have a problem with the word "believe" when talking about technology. People are free to believe all sorts of things, but technology is about science and engineering. One is not free to believe that 1+1=7, no matter how much they wish it to be. Technology is about what is really taking place.
No one is free to talk about a skin effect problem in context of some 2 meter cable at some 10MHz and many nsec rise time. Is it legal to misrepresent such facts? I do not know. But I know it is wrong technically.
Did you visit the article "Skin Effect" on my site? It took some time to put together, and I did it for just such cases as we are dealing with here. There are many cable companies that use skin effect where it does not count, including many makers of speakers wires.
You see, there is such a thing a a skin effect, and it does matter a lot at high frequencies, long cables, tiny thin diameter conductors. Strictly speaking, you can not ever say it is not there. If you put one grain of salt into a body of pure water the size of the Atlantic ocean, you can not say that the water is free of slat either. This is a pretty good analogy to skin effect "problems" for a 2 meter spdif cable.
