Thanks Jeff. I hear you on the location and speaker selection. I take it the difference in power (watts) isn't critical.
I think I am going to go with a Niles SI-1230 and then 3 connects. I can then have three pairs use the main input and then connect the other two Connects as inputs for the 2nd and 3rd zones. I like the Sonos App and will use that to control the source inputs, for now. But then have greater flexibility down the road. Thanks,
