\rHi David:
I have not heard from you since I responded to your first question regarding the MX-1260 versus a AMP300. The best setup would be two SONOS and two AMP200 (2) channel amplifiers. You can power the outside speakers with one AMP200 and SONOS Pre amp and power the inside zone with AMP200 with the SONOS Pre-amp #2, one pair of speakers on speaker A and the second pair on Speaker B. You can play identical source on SONOS 1 and SONOS 2 and you can control both from your smartphone or tablet. Or you can play different source material for zone 1 while playing some thing else on zone 2. The AMP200 is a workhorse and will have no problem playing as loud as you want.
