I have a pair of JBL 305 and a passive controller. I’ve been using a Schiit Modi 2 Uber which I love. However I’m getting some ground loop issues that I cannot seem to solve. Currently the setup is Computer (Laptop) -> Modi 2 Uber -> Passive Controller -> JBL. But often when another grounded device, such as an eGPU or my monitor, is hooked up, I get a high pitched hum. If I remove the power from the Modi 2, it is gone. I’m at a loss. I’ve read a ton of guides on ground loops, made sure everything was in the same outlet, tried different outlets, etc. My only work around is using a Toslink connection from the computer to the Modi 2 as I get no hum, but I’d like to use the USB input. Is it maybe because the Modi 2 uses a two prong power adapter?
