cables do not need to be 'warmed up'. If every electrical parameter of the cable changed 10% after warming up, it's doubtfull you could hear a difference. To exemplify that, changing the cable length 10% would changed all the electrical parameters by 10%.
More effective would be to spend this warm up time cleaning your connections or cds or your room!
