Added the ZoneBridge to my Sonos music network tonight. Very easy to install--it's pretty much plug and play. My ZonePlayer is now connecting wirelessly to my ZoneBridge and the ZoneBridge is connected to my Airport Extreme access point in my living room. Not bad for about 20 minutes of configuration and software installation and setup. I have a pair of Definitive Technology ProMonitor 1000 speakers connected to the ZonePlayer ZP100. Sounds great.
