The hum in constant, it only changes when touching the inputs of the speakers.
I'm not sure what you mean by this.
The baluns are muxlab500033, here is the plans for both racks. The HE2 is the one with the humming.
I agree with Fred, use a Jensen Transformer at both ends.
How far apart are these racks? Are they in different rooms? Do they connect to different electrical panels?
It seems unusual to me that a large, high quality system is using 3.5mm phone plugs for interconnects. What is the device that you are connecting to HE2?
Does this hum go away if you disconnect the cable feed?
