Turntable/Subwoofer Ground loop


I have a Rel B1 that is hooked up to Cary MB500 monoblocks via the high level connections.

I am starting to get a ground loop hum from the sub when I play a record. Only when the needle hits the record does it start. I have re-checked all connections, what could it be?

All the ground wires are connected what I think is correctly, but the high level connection from the amps to the sub has the wires stretched quit a bit to reach the amps and the ground.

Should I ground the Sub connection to somthing different, like the rack???

If you are not using a 3 wire speakon cable, make sure not to use two negatives on the high-level input. From speakers: Red and black on left speaker. Red on right.
