Just bought a Play 1 and Play 3 and using through iTunes on my MacBook - fantastic, I love it! I plan to buy a Synology NAS to store my iTunes library, to allow Sonos to play music when MacBook is not in use. However I want to keep a copy of the iTunes library on my MacBook to allow me to play music when I am away from home, and to allow me to sync music with my iPhone. Is it possible to copy (not move) iTunes library to a NAS, and have Sonos still access the copy on the server, but to use the iTunes on my MacBook through, for example, Bluetooth speakers? Sorry if this is a NAS or Mac topic, rather than Sonos specific!
