  1. My "evidence" is  the maths. If you don't believe that the L,R, C, in coaxial cables used in stereo system interconnects  (in the lengths typically used in those systems), then do the maths yourself! They don't lie. And the maths say that in order for a 20 KHz signal to encounter a measly ONE dB of attenuation (which has been proven that no-one can either hear or notice and, unless one has an expensive AC volt meter, can't even be measured by anything that any audiophile is likely to have), requires a RG-59 cable more than 50 feet long. That's just fact. Get the LRC values per foot from Belden's or any other cable manufacturer's site and multiply those values by 50 and use the standard impedance formula and 20 KHz as the frequency and see for yourself. And no, it's not possible that other brands of coax will have significantly different values for LRC. Even so, it would take values that are orders of magnitude greater than any that a length of coax could have to cause a greater attenuation, and decreasing the LRC in a cable, would only move the -1 dB point either higher in frequency (and thus even more inaudible) or it would take even longer lengths to reach the -1dB point at 20 KHz. None of this is conjecture. It is fact. Like I said do the maths.

     

    Sorry to take this to a private message, but Chris has locked the thread on Belden's Iconoclast cables.
