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.

fuzztone- reread my post. You can’t get any further downstream than my speakers. At what point am I confusing my Streamer from my DAC? I make it a point to ignore your posts. The other responses are very helpful as they understand my issue pretty easily. Thank you erik_squires and jacobsdad2000. I have a few devices on order.

The hum from the DAC itself does not travel throughout the chain to my speakers. Last night I taped over the Ground Pin on the USB cable. No hum from the DAC. I ordered an iFi USB isolator which is supposed to cancel the hum.
