I've seen ostensibly high quality XLR cables that connect the cable shield to pin one only versus some that connect the shield to pin 1 and the connector body (which is typically earth as opposed to signal ground). I've also seen cables arranged with each end treated differently. I've read that the best practice is for the shield to be considered part of the equipment housing and be connected to the connector body on both ends but that seems like a excellent to way to increase ground loop sensitivity. I have seen cases where not connecting the shield to the connector body as well as pin 1 seems to increase the susceptibility of hum being induced (e.g. cable near to pedal PS picking up hum). Any opinion/experience on a best practice/method for handling pin 1 and connector body most likely to give good general results?
