The hum is likely due to a difference in the ground between the two components. You could run a small wire from the case of the the OPPO to the case of the 1070 to ensure they have the same ground.
This would be a good place to start if it is a 60Hz hum. You could back off chassis screws on each piece of equipment, wrap a piece of speaker wire around counterclockwise and tighten the screws back down to the chassis.
