Hello. I have a grounding issue with Rega P2. I know there are already threads about this. So Rega claims you don’t have to ground your turntable because it is already grounded with rca. But it seems in this system nothing is grounded because Rega Fono MM has a simple DC adapter with two pins and Rega IO amp has 2 pin AC mains socket. Am i right about nothing being grounded in this setup? The only way to ground this setup looks like connecting a wire between wall plug’s grounding pin to the amp or the fono preamp right? Rega is such a pain or i am dumb.
