I had this same issue with my Rel Stadium III, after I changed from at stereo amp to mono blocks. Take the ground wire and connect it to the grounding terminal on your preamp. I also hear that Rel makes a cable for it with 2 ground wires but I have never seen it.
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???
