I am not recommending you do this. But one tweak in this area is to remove the outer jacket from certain cables. These cables include Straightwire and Wireworld where a cheap plastic outer provides protection from the cable being stomped on. The improvement in sound is apparently largely due to the fact that the cheap plastic outer is a source of electrostatic problems. I have heard jacketed versus unjacketed versions of the same cable and the improvement is a much smoother sound. With jacket on, the sound has an artificial crispness to transients.
