Trying to set up my new Pro-Ject Debut Carbon Evo that arrived today, and I have run into a bit of a snag. It seems the table wants, and came with, an RCA cable that has a ground wire with it. I have this Rolls Phono Preamp to hook it up to, and it has been a few years but IIRC the little spinny thing above the PWR connection on the preamp is the ground. Unfortunately, the U shaped connector on the cable and this spinny thing seem incompatible, as it won't fit around the inner diameter of the spinny, which is built with a hole to shove a bare wire through and clamp down on it.

What do? Cut the connector off, strip the shielding, and run that wire the way God intended? I'm kinda posting this in case someone has a reason not to do that, but I mean, that should work fine right?
