Breaking in speaker cables??

ACTUALLY; this is the level of Tesla Generator that I had in mind: (http://www.youtube.com/watch?v=FY-AS13fl30&feature=related)

@ MR P: One must discipline oneself to ignore the concrete minded(throughly mixed up/permanently set).

There is no, "positive" side to an AC outlet. There is a HOT leg, and NOTHING will flow, if a wire is connected between two hots of the SAME PHASE. Current will only flow if a NEUTRAL is attached, or if both HOT legs of your incoming 230V service are attached. In either of those cases; there had best be a load connected(ie: lightbulb/230V appliance), else you will have(of course) created a dead short.

Rather than having to wait for a lightning bolt to happen along; you can build a Tesla Generator: (http://www.teslagenerator.tv/) Then again; here is a more civilized and controllable method: (http://phonoclone.com/diy-rack.html) Build it, as instructed for non-polar resistors(last sentence) and install a 10 Ohm/50W resistor, across the speaker ends of the cable. MoFi's method, with a Pink Noise CD(on repeat), is what I've generally used for my cables though(plus lots of listening).
