Default DSP20 Making noise

Any DSP20 owners out there experiencing their units making a loud humming noise? I am powering a Bryston SP4, 2 mono blocks, my sub and a streamer from it. I called PS Audio last week and they had me unplug my Bryston SP4 from the unit and go directly into the wall with it and do a firmware upgrade. Unplugging the SP4 from the unit did get rid of the hum for a short while but now the hum is back and louder than ever. This is now my 3rd DSP20, the first one I had to return BC the touch screen did not work and the second one arrived damaged from shipping. I’m starting to get a bit frustrated and wondering if anyone else has experienced these issues? Thank you.
