Inductance, iirc, is related (for a "normal" wire) to the diameter of the conductor. The capacitance of the cable is related to the distance between conductors.
By normal wire, I mean one that is not a spiral like the old Krell/Symo stuff for example...
Some mfrs do things to add capacitance (shunt capacitance) via the relationship between the wires so as to offset the self inductance of the cable. Dunlavy's patents might make for good reading on this sort of idea.
Personally, I'm against this sort of idea since it rarely seems to yield a cable that sounds good to my ears. What seems to happen is that the capacitance wrecks havoc with the output waveform of feedback amps. For non-feedback amps (the few out there) the effect is different. So, IMHO, these sorts of cables never sound alike on two different amps or speakers. Unpredictable.
I try to minimize the inherent inductance and capacitance effects and feel that results in the most predictable and stable cables.
And again, the internal geometry of any cable will play the major role in its sound, the wire, materials, and the like being more secondary or even less important. That's not to say that you can not hear any of these effects when comparing identically built cables with one item changed, you often can.
So, the idea is that if you use two different lengths, usually the basic L & C values will be different enough to cause some differential in what you may hear. So, go for two
identical lengths, and DON'T COIL the excess cable!
(it makes an inductor) :- )
