Hi Groovey, seems to me there were several recently, focused more on balanced phono sections and the like.
We've used this setup since 1989 and before us no-one was doing it.
Any cable manufacturer can make a cable for you. If you have a five-pin plug at the output of the arm the job is very easy. If you have RCAs at the output it is trickier but still possible.
I've had good luck with Purist Audio Design, Kimber, Silver Audio, Magnan and in my Triplanar the arm was made with balanced outputs as a stock feature.
