There was a mild hum coming from the headphone amplifier that I could not eliminate. I narrowed it to the very crappy power in my area and that I live in a 1930 building with a shoddy electrical network.
What I have done and worked for me:
Furutech Flux 50 NCF (rhodium) into Niagara 1200. Amps are plugged into the High current outlets of the Niagara. The hum is gone, and the sound is better. Caveat, this worked in my particular context; others had success with gear and methods that I didn't.
This was a gradual process with a lot of trial and error: Moving the setup around the house, trying different outlets, killing wifi or Bluetooth. Tried iFI power station, DC Blocker, and ground defender in different positions, fancy power cables that improved the sound but did not eliminate the hum, an APC voltage regulator, ... the works.
