I dialed the hum out today.
It's pretty easy to get ~6mV of hum by ear, I couldn't get much lower then 3.9mV - 4mV with the voltmeter using the low pass filter setting.
They are effectively silent.
Obviously they sound a little better with the hum eliminated.
For shits and giggles I decided to separate the chassis, earth ground and electrostatic screens from audio ground. This introduced a bit of higher frequency hash, so I put it back to how it was.
Also worthy of note, regular 1A fuses have been working in my application, they are well behaved little amps.
