Hi - I have SONOS with my B&O.
I have a Synology NAS with all my music on it connected to my Router. I have one of the SONOS boxes also connected to my router and the 'phono out' goes into my BEOSOUND 9000 aux.
Its awesome and something my wife actually uses. Basically iPod your house.
The remote control or the SONOS app on my iphone is a joy to use with cover art showing etc. Playlists easy to add to - finally 80GB of music is actually getting listened to, as well as thousands of streaming radio stations...
Range is terrific - parties are fun with people using the remote to add music..
Awesome - get it. Two of my customers have also purchased after my recommendations and viewing various web sites,
Cheers
Russ
