Not only is your grado not shielded, which in many applications is of no consequence, but more importantly the AR's motor is not shielded either, and it is making your system hum. I bet it gets worse as the arm moves closer to the center. Audio "lore" has long warned against mixing grados with ARS. That being said, it can be done either by getting your dealer to order a version (which they used to carry) that is less hum prone, or by shielding your table's motor. I have no experience with such shielding, but I have read posts where people used "mu metal" what ever that is. Apparently it is used in rf shielding. Russellc
