Super long speaker cables

Here's another good source of information for anyone who's interested in accuracy rather than coloration from their cables:

As for Twl's rather astounding rewriting of engineering history, there have been absolutely no major breakthroughs in scientific knowledge about cable performance at audio frequencies in the last two decades. Everything he mentions was well known and understood decades ago.

I don't know, Twl, Russell seems to have a pretty good technical handle on his subject. I wouldn't assume he didn't know about something just because he didn't mention it. Perhaps he is well aware of what you seem to think is missing, and just discounts it as an audible factor. As would anyone with his training and experience, I should think.
