I already have "built" two of these couplings. Got my stereo crazy in the room and now needed a "renewal" for multiple devices. Thanks to this clutch I could use the appropriate cables and further extended simply by remaining cables. Audio differences I could not even notice. Have a jack - extended> RCA cable from the PC and the audio RCA outputs of my Playstation 2 extended up to the stereo system. Everything without problems. Contrary to article Picture one side is red and the other white.
