Well... my hum is gone. FWIW, I tried putting the CBII in the signal chain in various spots. The first one was between the BFD and the sub, right by the sub... still humming. Next was between the BFD and the sub, right by the BFD.

The place that worked was when I put the CBII between the receiver and the BFD. Ahhh... silence.

For the record, the run between the BFD and the sub is about 20-30 ft long and runs in the wall. It is RG-6, which I finish with some nice compression connectors.

Hope this helps,
