A truly brilliant product, five star, which in any case I think during installation. Installing and setting up, coupling with existing devices (NAS, Tablet, PC, Internet, ...). Everything described as simple and innovative as in many other reviews. Even the sound that has a PLAY5: disseminated in space, exceeds my expectations. The long shopping list for the complete interior I have in mind (Play: 5, SUB, Connect, 2 x Play3 :, ...). But then ... As this is really meant by power consumption in standby? One question that I had some returned to my first enthusiasm. About 5-8 watts per device and no switches! In my expansion that would mean at least 30 watts in standby. Why such an innovative and well thought-out product patzt calculated at this point, do not open up to me. Hoping for improvement in a secondary product by Sonos I set up my first time buying back and draw 2 star from my initial impression.
