Hi Thomas. Although there really isn't an official consensus, I have always heard "lift Pin 1 (ground) on the input" side of every connection. This way, the shield is connected to the audio ground of the output device. EMI and RFI are less likely to be picked-up by the input of the receiving device following this rule. I do this for all of my balanced connections, analog and digital. With digital interconnects, we don't have the "luxury" of hearing noise or hum on the connection. The connection will either pass a valid signal or not.
Furthermore, I recommend that you check all of your digital interconnect from time to time by passing a 192kHz signal through all of your connections via your router or otherwise. Often, there are weak connections that can pass 96kHz and lower signals without interruption, but if you go to 176.4 or 192, you might experience loss of lock. This happened in my studio, and was due to some bad solder joints in a few terminations. Once repaired, there was a noticeable improvement to the audio at all sample rates. To repeat a famous quote from Bob Ludwig, "Never Turn Your Back on Digital!".
