This idea sounds appealing, but wouldn't that also (generally) require standard power (115v/60hz stateside) to run the amps? Not having to worry about having an electrician run the appropriate 'high voltage' (in a residential wiring context) power to ceiling/wall speakers is appealing to me. I'd love any additional resources you have about this method though.

Uhh, no - you run 110 to the symfonisk, and run 2 pairs of speaker cables to the bi-amp speaker.

Oh, I understand. For some reason I was thinking self-powered (internally amplified) speakers that were being driven by a line-level source off the Sonos. Not sure why that's where my mind went, but appreciate the clarification!
