Murray, I guess that 'a' is 'Litz' or some fabrication from Cat5 style, 'b' is NACA5 and 'c' is two bits of ordinary copper wire laid side by side.
You can expect audible differences with these cables dependent on what you connect them to. Sometimes the smoke will come out of the amplifier and that is guaranteed audible.
But this is completely irrelevant. The cable makers and believers claims are nothing to do with the well known effects of cable geometry. It would hardly be possible to charge $8000 or more otherwise.
