Perfecte Multiroom - solution - no more, no less!

Who wants to link his home sound technically, comes to this system probably is not over. A bridge connected to the local router, and then install only corresponding boxes for each room and claim and connect with a click.
Then in all rooms enjoy music. All in stunning quality and variety of possibilities. Never were mp3 collections valuable. ;-)
Music from the Internet - which is DAB? ;-)
So why only 4 stars? I am referring to the entire system. First, there are the considerable cost. When I go out of about 6 devices, quickly comes a sum of an average over 1.2 thousand to two thousand euros. For standby power of about 5W per box (Sonos Forum) in a nearly three-digit amount. Or always pull the plug. External devices are left out. An analog audio input into a several hundred-euro Connect or Connect Amp. Or opt connection in the soundbar. Who before has to involve foreign devices (BR player, TV receiver, Play Station, etc) quickly reaches its limits. An equally expensive AV receiver can there by a mile more. (And technology obsolete quickly) My home theater system I will definitely not trade.
If all that does not interfere with, certainly with Sonos Top Audio System.
I've bought the Play 1 in combination with Airport Express v. Apple for the kitchen. There, they also do their service. But an extension I do not think of said reasons.
