I am disappointed to report that unplugging the LED lamps from the circuit (shared with the Universal Player) did not cure the hum problem.
It must be a more serious and/or fundamental issue.
I am electrically challenged but if I were guessing, I would say that the problem may lie with a long interconnect defeating the filtering applied to the switch-mode power supply inside the player itself (allowing distortion to leak through) or that I have a ground loop issue that only affects components with switch-mode power supplies.
