I've read various forum posts about this sort of issue, but remain a bit confused about the possibilities with my unique setup. (I'm coming from a house where I used Sonos in a conventional sense with multiple Play 3s, an AMP, and Bridge). I bought a new house with a built-in distributed sound system by Russound. It consists of a multi-zone amplifier which feeds 6 zones. Each zone has a wall-mounted controller (on/off, volume and source) with in-ceiling speakers. http://goo.gl/uJuPeJ Currently, I have an Airport Express hooked into the "CD input" on the amp and use an iPhone/iPad/Mac as the music source which is controlled with the Apple Remote iphone app. It works okay, although with this setup, different music cannot be played in different zones. So, first question -- is there a way I can use Sonos technology (?CONNECT and CONNECT:AMP) to give me multi-zone control? And second question: If the above is possible, can I enhance some of the existing zones by adding the free-standing Sonos speakers? Thanks for anyone who took the time to read this all the way to the end!
