John,
Have to back up everything Messiah says. It really is the 'bees knees', 'mutts knutts' etc. etc.
I have 3 zones and 1 controller and the only thing stopping me getting more is financial. This kit slots in at number 2 of things I couldn't live with, the iPod being number one and Skyplus newly demoted to number 3.
I saw this system in a magazine on a Tuesday, did the research by reading the reviews ordered it in the afternoon and it was delivered and installed by Thursday. I though I was in for a kicking from the wife as it was another unauthorised spend but she loves it and that's because it just works.
I had two minor setup problems which were easily solved. Firstly there was interference with my DECT phones but that was fixed with a change of wireless channel on Sonos. The second was more awkward, I was running Checkpoint Securemote client on my PC to give me a VPN link to my office and Sonos didn't seem to like this. The only way round it was to disable the VPN s/w but Sonos are looking into it. As I don't use the VPN very often this is not a big issue.
It seems to me that Sonos have brought out a fully featured and well thought out product. Check out the forums on
www.sonos.com for lots more happy owner. Buy it you won't regret it.
Oh and by the way if you plug a source into one ZonePlayer it is available on all other ZP's - how cool is that!
