Funny how all those points were just whizzed on past by jneutron.Re the one point he tried to turn into a mountain, he failed to answer my further comments about cable inductance, and whether or not 8-10 feet of zip cord had enough inductance from one end to the other to mask some of the capacitance at the far end.
Given the referenced URL re dielectric constant of PVC DROPPING with increasing frequency, I still think that the dominant effect is going to be that, and not the masking of capacitance due to cable inductance.
I find it telling that in his other article, The Speaker Face Off, see:
http://audioholics.com/techtips/audioprinciples/interconnects/SpeakerCableFaceoff.htmhe shows that the two cables that did not have PVC insulation, the Stealth brand cables which used teflon, did NOT show a decrease in capacitance with frequency, despite the one Stealth model have MUCH higher inductance than zip cords, see Fig. 3. on page 2. In this article, he stated that he used either 6 or 12 foot lengths to take the measurements, which would be enough to see if there were a per foot inductance masking issue.
I think that this blows jneutron's supposition out of the water, and corraborates my take on the matter. Or perhaps we have another huge error on Gene's part, either way, it buttresses my point, and Gene/AH is wrong.
