Take both mono block out of the circuits, connect a headphone amp to the ARC ref3 output and listen if hum still exist?
In some case, hum is caused by upstream equipment.

Krell KAS amplifier hum
The amps are directly plugged into their own dedicated 20A outlet. Is there a "conditioner" I can use to minimize/eliminate the mechanical hum I'm hearing through my MBL 111f speakers. I'm not looking for a multiple outlet item, rather, one which plugs directly into the wall and into the back of each monoblock. Please advise and thank you in advance.
Best,
Jose
