No there is no advantage to the sound quality but the convenience is just great! I can now remove and replace my speakers from their position in seconds (so I can hoover behind them) compared to the ten minutes fiddling about before. It doesn't matter if you use them at one end and not the other. If you use them make certain everything is tight or get them put on for you by a specialist firm. If they are not put on properly they may do harm to the sound. The most you can hope for with 'nana plugs is for everything to remain the same soundwise!
