| Re: What solution do folks use for the dreaded BFD hum? Actually, after rethinking this, I would definitely place the Cleanbox close to the BFD and run the longer unbalanced lines to the cleanbox from the receiver.
The cleanbox's job is reject noise. Even though the line feeding it is unbalanced, the common mode rejection will be very high since transformers tolerate the mismatched source impedance very well.
The short lines on the output of the cleanbox will offer the lowest distortion and overall insertion loss.
