If like me you have a network running the PLC, it is essential (and only the first time) connect your PLAY5 by removing the PLC connected to the box, otherwise unable to connect) then you can get your CPL and install your PLAY5 wherever you want. It really is an easy, pleasant and quite powerful. I use either my iPad or my iphone without worry. The sound is clean and true (I listen to music from India that require good sound subtlety).
