LS50 Wireless with turntable need a ground wire?

I wasn't sure which forum to post this in. I’m going to connect my Pro-Ject Debut Carbon DC Esprit turntable to my KEF LS50 Wireless via DH Labs Silver Sonic Air Matrix RCAs. There’s no ground connection on the KEF side. Should I skip a group wire or connect to something else on the KEF side?

Thanks for any input.
