I checked my system. No hum. Hum is weird. I always expect when I turn my system on to be "business as usual" but your experience brings back my struggles with hum. Your system is "perfect", then next day you have hum. You have two systems. Check your reference system for hum.

Hi, my main system is dead quiet in any situation.
The new Mcintosh system were all new to me.
Both Mac were used. Cables were mostly temporarily.
And the worse of all, each individual made its own hum .
The C2200 was the worst, it needed service for sure,
It hum strongly as soon as the message tube warmup gone.
The MC2102 made a very little hum..
The JBL hums by itself too.
So when all three combined, it was quite a challenge to
Identify for source of hum.
Hums from JBL and MC2102 I needed to put ears within a foot or so from speakers to hear. May be 1-2 dB loud.
