cartridge leads

I've ordered a new cartridge, so naturally I've started obsessing about the coming setup. I have all the usual setup tools (gotta get more Kontak) but am wondering about using new wire leads between the cartridge and the tonearm. I'm using some silver wire things now, have some allegedly gold wire things in waiting, but keep remembering ads for this and that super cartridge lead. Since changing other wires in my system have made significant sonic gains, it only seems reasonable that changing the wire that carries the smallest signal could too. Anybody have any suggestions?
