There are 2 kinds of 60Hz hum.
the ground loop hum that affects audio signals, hard to remove. usually with balanced power like furman it-20 series ][.
&
the transformer 60Hz hum inside equipment,
easy to remove with psaudio.com humbuster3.
theres also other brand but cant remember the name, also has less watts/amperes capability.
