Rlawry, I could be wrong but I interpreted John's indication that "my other speaker cables measured ~ 0 ohms" to refer to a completely different set of non-HFC cables. I'm sure he'll clarify, but I suspect he was saying that he only measured the HFC cables on one channel, his "quick check" not including taking the time to disconnect the cables on the other channel. And of course the difference between the two conductors on the one channel was minor (5.6 vs. 5.8 ohms, some of that difference perhaps simply being due to the resolution and accuracy of the meter itself).
