LS50 Wireless with turntable need a ground wire?

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 preamp.....run 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.
