Not inductance only! Cable topology, and wire composition (not just material, but the stranding and shape are big factors) determine how fast the different frequencies propagate.
What most folks forget, is that an audio signal is a wave in a metallic (usually) medium. And although electricity (electric potential) may transmit at the speed of light in a theoretically perfect medium (ever hear of "super-cooled super conductors"?) an electric "signal" does not, and is very much medium dependent. What do you think the doctor is looking for when he/she checks your reflexes? Wants to see if your cables are deteriorating.
