3. Use properly designed XLR cabling: a proper XLR cable has signal conductors for the pin 2 and 3 connections, surrounded by a shield which is connected at both ends to pin 1. Nothing else should be connected to pin 1. Some audiophile cable companies do not do this correctly, so check. There should not be any wire connected to pin 1, pin 1 is shield. Inside your components the XLR shell, and pin 1 should be connected directly to the chassis, this creates a continuous shield of the chassis-cable shield-and the subsequent chassis.
