There are measurable differences between cables so why should there not be be audible differences as well? Some cable makers, (too few), publish electrical parameters for their speakers, (resistance, inductance, capacitance). You might expect that a cable with high inductance / low capacitance would emphasize bass. Maybe you could use zip cord + an inductor to achieve the same effect or maybe not: it would depend on the overall result. In any case, lots of people claim they can hear difference between similarly spec'e capacitors and inductors.

Proof is a difficult think. As RGA points out, DBT (double blind testing) cannot prove the negative proposition that there is no difference between A and B. Tobacco companies long claimed that there was no proof that tabacco caused disease: stricly speaking they were right. But we -- and they -- really knew better.
