Some hours reading the back issues of the journal found at
http://www.compliance-club.com will hopefully inform you why star grounding
is a thing of the past. Ground both ends. If you are afraid of ground
loops,  place a heavy (as in 10-16mm2 or AWG way below 10) ground conductor
alongside the signal cable, and ground it firmly in both ends. That will
take the current away from the shields. 

Ungrounded shileds are inefficient for EMI and RF shielding, while at times
efficient AC hum blockers. 

And, IANAEE, but I've played with big sound systems that exhibit all these
problems.
