Can anyone recc. a good wireless surround sound system? We want one for the back room but we aren't sure about the sound quality of a wireless one? All of our couches/chairs are near wall sockets so thats not a problem, but it's the cables from the DVD/Blu ray player to the speakers that make it a problem. We can't put them under the carpet as we've just had new laminate fitted Anyone got good reccomendations of ones they've tried?
