Dielectrics and such...??

Al, I didn't notice the link you provided. I agree that 22nH per foot would be extremely low and we can take it out of the equation. So what else is there (other than resistance, inductance or dielectric) to consider?

So what else is there (other than resistance, inductance or dielectric) to consider?

Nothing else that I can think of, beyond what we've already said. I don't think that dielectric absorption will be an issue. The electric field between adjacent paralleled cables will be minimal, partly because of the one-inch distance, and partly because of the cancellation resulting from the twisted and braided construction of the two conductors in each of the four paralleled cables. Also, depending on which of the two physical configurations I asked about is used, the dielectric between paralleled cables may be mostly air, which as I understand it has essentially no susceptibility to dielectric absorption.

Total capacitance (between + and -) for a 2.5 meter run (about 8.2 feet) would be 1448 pf, somewhat on the high side but I suspect still low enough to not have audible consequences with the great majority of amplifiers.

Al, that's perhaps why some manufacturers use foam Teflon (including my Acoustic Zen Absolute ICs) - not only to lower dielectric constant but to reduce absorption (introducing air). As for driving 1.5nF - I'll take your word, having limited experience.

Hi Ben, here is my experience. I have Kimber 3033 and tried to protect them from dust by wrapping them up in a thin plastic sheet, those used to keep food in the fridge.

Result was a huge change in sound for the worst. Harsh, unmusical,..., forcing me to remove it. Once done, good sound returned.

I admit I covered the whole lenght of the cables with the plastic sheet. Maybe using a short lenght of tape might not have the same effect.

Good luck.

Jbuenech - that's good input and certainly makes me rethink my original strategy.

Al and Kijanki - You guys are both so knowledgeable and I always look forward to your intelligent responses.

The Kimber 4tc, as you likely know, is comprised of multiple twisted ("braided") wires including both the positive and negative runs. I want to use each "braided pair" (one complete run of the 4tc) per speaker terminal (2 runs - one to each of the top/bottom positives, and 2 runs - one to each of the top/bottom negatives). My thought was to run the four runs parallel and evenly spaced. Perhaps I should twist the runs.

Please help me determine the best approach to twisting:

1) twist the top negative and top positive separately and twist the bottom negative and bottom positive separately.

2) Do step (1) - above - and then twist those two "twisted pairs" together to form one large twisted run (with all four cables).

3) Twist the two positive runs together; twist the two negatives together; and then twist those two twisted pairs together...

4) Don't twist - run parallel/evenly spaced.

5) Other...

Thanks guys.
