I bought this (expensive) audio extension cords as those which I previously (cheaper) bought always generated from the speakers an extremely unangehmes noise when they were plugged into any source (free lying around). This works very well made (subjective impression) and absolute produces no sound / noise. Bin 5/5 stars satisfied as they meet 100% of my expectations. About playback performance (better / worse) I can not say anything except properly - because I do not pay, it had also not super expensive equipment.
