A:Answer The Sonos Amp would bypass the need for the Russsound volume control. The Sonos Amp is 125w at 8ohms. So you would just need to calculate the power according to the speaker's features. More than likely, yes you would be able to run both pairs on one Amp. Keep in mind that if you do this, they will only be able to play the same thing at the same time. If you would like them separated to play different things in different rooms, you would want each pair on it's own Amp.
