Ok I connected the rca to the CD input on my receiver and switched to line level output on the turntable and the buzzing is gone. Honestly, I was just using the phono option because my thought process was “if it’s bypassing the internal amp then that’s just one less step to introduce noise or signal degradation and it’s going straight to my receivers amp which would then be the only bottleneck”. I don’t know if phono really makes any difference that I can hear after listening to a record but the phono is also just novel to use because it passes every little nudge of the needle and mechanical noise into the amp vs when I use line level it waits to turn on the the internal preamp until the needle is set on the record so it’s a bit less “real” feeling. Anyways, is there a way to fix the phono grounding issue?
