Hello cetla416! If you decide to replace some of the components in your system, look for units that allow you to use optical cables. I solved a hum problem in my big system that way. Good luck otherwise!
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.
