I agree. Hum is most likely due to the power supply-generated EMF being picked-up by the SUT.
Here lies the reason for my initial question. Since the internal SUT, no matter how well shielded, is in close proximity to the internal PS, it hums. Then physically removing an external SUT away from the VR power supply, in theory may produce less hum
