The proper procedure is to play the thing. You will likely suffer much less than folklore has it. It isn't as good at first as it may become but it isn't usually that wretched or that intolerable while devolping. It will burn in with use. If perchance it is unbearable while going through the burn in just do as the others have said get a dynamic CD attach a load (I disagree there) and leave it on repeat until its nice and toasty.
