I use this cable to my subwoofer to the amplifier connected. All previous cables have communicated with my shutter control - to be called every time I have the shutters driven up or down the sub has turned unintentionally. But this is now over! The cable is so well shielded that the control signals are no longer consumed by the subwoofer. At the sound quality I have also nothing to complain about - for me a strong buy recommendation!
