I forgot to mention you may want to check what's in the "vicinity" of the cable routing. If there's anything with iron content along the routing, that will affect cable inductance (relative permeability). Air is best. Cable capacitance will also be affected (relative permittivity) by various oil-based products, glass, etc. To keep capacitance as low as possible, the cables ought to be surrounded by air. Concrete for example is 4 times more permittive than air making the capacitance 4 times greater so raising the cables off the floor may improve bass!
So how you route each cable is important. If you want to get really anal about it, you can't route one cable in the "vicinity" of the other even if the other is not powered.
The other things that matter to inductance and capacitance are the insulation, the distance between the two conductors and the cable length. The difference between the diameters of each conductor matters too but I'm quite sure the conductors for each cable are identical so that difference is nil.
