I bought the pro-ject turntable with the pre-amp that was recommended by Sonos to connect to a sonos 5. I was getting a loud low hum coming through the speakers and I couldn’t find a way to ground the turntable to the speaker. I tried buying an upgraded rca cable that didn’t have the grounding wire, the sound quality improved a little but it still has a very heavy low hum. Is there a way that I can ground the other end of the wire to the line in on the sonos 5?
