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.
Do the speakers have a phono stage as well as  line level inputs not sure that TT can used without a phono stage. 
You’ll probably need a phono the ground to it.
Thanks for the replies,

Yes, sorry I am going to need a preamp. This is my first time attempting a turntable with the KEFs. So do I just buy a separate ground wire for my turntable (Pro-Ject Debut Carbon DC Esprit) to my preamp as my RCAs (DH Labs SS Air Matrix) don't have one? Then will I be OK running something like a BJ LC-1 without ground from the preamp to the KEFs? In another thread everyone mentioned to use my better cables in between the preamp and turntable.
Only need to ground turntable to phono stage pre-amp. That’s all. If you have hum or pickup a local radio station then get a Hum-X. Miracle device for my system. I live in urban core.
