shield to pin one of xlr


I have an einstein phonostage with only XLR inputs. I am constructing a tonearm cable. Most schematics (ayre, boulder, aquavox) recommend connecting the shield to pin one. Some schematics recommended just leaving pin 1 not connected. The shield is either not connected or connected to ground on the phono stage.

What is the advantage connecting the shield to pin 1? I would assume that it is related to how the phonostage handle the pin 1 connection.

Thanks

Guys, many thanks for the help.

Just did more experimenting. I turned the volume way up to hear the bakground noise. Then ran a wire betw the ground of the phonstage and tonearm, tonearm base or table. There is no significant difference in noise level or sonics.

Also tried the setup by opening the connector at the phono end and inserting a wire betw the shield and pin1. Again no significant difference in noise level.

I am not experiencing any problems with noise at normal volume setting so I am going to float pin 1 and leave the shield disconnected.
