"While any premium microphone cable will serve, I would stick with Mogami 2534. If you are terminating with RCA connectors, connect both the blue wires to the centre pins, both white wires to the outer rings (or vice versa). Connect the shield to the outer ring at the amplifier end only."

It's always been my understanding that the shield/drain is only connected to the sending end of the cable, so with a preamp/power amp connection, that would be preamp end only.
