Input output cable question

I am sure this question came up before.  Can somebody direct me to the discussion here?

Hi Bill - for the most part, with Aurender, the AES/EBU should give you better performance.  If in doubt, try borrowing one from The Cable Company and determine for yourself.

I have a Aurender W20SE and the output of the AES is subtly better… keeping the quality of the interconnect the same. 

Should be a little bit better sound quality and the connector itself is much beefier and snaps in and locks.  Worth it just for that...
