Speaker hum


Would going from a 90db sensitivity to a 98db sensitivity speaker uncover a hum? I've been doing all the plug / unplug / cheater plug moves and haven't found it yet. It started when I swapped in new speakers and it's making me crazy. I have a 2-20 amp duplex receptacles fed directly from the breaker panel, same buss bar and grounds tied together in the 4 x 4 box at receptacles. I have an Odyssey Stratos Plus stereo amp and a NAD - C 658 BluOS Streaming DAC/Preamplifier.

Is your set up attached to a cable box, i.e., you play your tv through it occasionally?  This is a commo source of hum, which I have experienced.  Needed to simply purchase a Jensen VRD-1FF IsoMax Digital RF Isolator which handily took care of the problem.
