Or better, use devices designed with a propper grounding scheme and avoid the Raspi DAC for anything critical.

The raspberri pi isn't a dac, it's a streamer. It acts as a middleman to avoid using my PC as the source of the audio.

I'd definitely prefer a DAC with good filtering on its inputs so I wouldn't need to use a middleman, but that is expensive. One with a proper USB module with complete isolation can run ~$5000.
