BUY THIS it will change your LIFE! I had the same fears, having gone for Squeezbox far too early (5 years ago!). Sonos was around and 3 times the price and squeezbox seemed to do more. But squeezbox never worked, always dropping the connection, needing rebooting of everything....arggh. Got this Sonos plugged into my amp and it connects to my NAS (is Wmdpro but doubt it matters), wakes it up, plays all my music - took less than 5 minutes to set up, total breeeze. You can make playlists that will play a song of your NAS, then your music service (i use Deezer) and even your phone. Got a mate with Sonos too and he can come over, use his phone to drop stuff into the queue of what's playing, using his Spotify account. My music is reborn...I am sooooo pleased I bought this. Waste no more time!
