Ive raised it a little above my receiver on a temporary shelf, laid a towel under it, removed the dust cover when I use it, and switched the MC/MM switch on the back of my receiver to MM and have had drastic improvements!*
However, I think there is a ground issue. After I use it for a few minutes, a humming starts. If I touch it, it stops, then comes back after about 30 seconds. When I let go, the humming once again stops but then shortly comes back.
Note: there is no ground attachment on the turntable, just on the receiver.
