DAC USB Hum

I’ve had my Innuos Zen Mk3/MHDT Orchid DAC setup in my system for 30 days or so and I’m very satisfied with this combo. The Zen is USB only. Just noticed today that I’m getting a slight hum from the DAC and it goes away when unplugged. No hum through my speakers when connected just the DAC. Any help with eliminating the hum is appreciated.

Of course sir, maybe I should have mentioned it.

Easily observable by moving the box and cables around.

I guess I assumed that maneuver is much easier than posting here

A DAC is not a streamer. A few DACs have built-in streamers - not this one.

What is a "slight" hum?

Does it show up in the analog downstream during a listening session? Is it a recent phenomenon?

Hum is a grounding issue.
