Last year I renovated my holiday flat and let install a CAT7 based "Masterlink" system. In the living room I have a BeoSound 5 and in the kitchen a vintage BeoLab 2000. It works perfect, I have my homecountry radio stations in each room and/or my favourite CD´s which i copied via iTunes to the BeoMaster5.
Up till now I dont know any other system, which can combine this digital music with high grade of design.
