I've read your needs carefully. So you really only need the signal from the sonos amplified? The funny thing is you can find a 100watt receiver, which should be good to power the ceiling speakers (outdoor and ceiling speakers need a lot of power to make good sound because of there inefficient design) for much less then a straight amplifier. Although I was going to go with a sonos set up, I ended up buying receivers for the area's I needed with Ipod connections. I could easily buy three Onkyo stereo 100 watt receivers on Ebay for less then 1/2 of what a mulit speaker receiver cost. As long as you can control the volume with the Sonos, they will work. I've seen the Onkyo 8522 for around $100/each at times on Ebay, even at Amazon.
