Dave,

If the black wire in the interlink 300 is connected to ground on each end of the interconnect and the shield to only one end I believe the potential for ground loops is still the same (through the black wire). Wouldn't the black wire also make a connection to chasis ground on the amp side via the black wire, negating the directional nature of the shield?

Your common sense discovery efforts and expertise in this area are greatly appreciated.

Thanks,
Ron
