Talc is actually an abrasive. That's why it'll make a TT's belt grab better.

Help! Will lubricant affect spkr.cables?
My H.Tech. Pro-9 bi-wire speaker cables are a very tight fit when trying to slide them up inside my B&W speaker stands. If I put some lubricant on the outside cover to help slide them through would it affect the sound of the wires? Any recommendations? I don't want to damage the casing in case of future resale.
