Multizone

Using the SR7011 with no other equipment, it can do 7.1 with 1 additional zone. To do both zones, 2 & 3, options are do 5.1 in the main room or with 7.1 in the main room, add an additional amplifier for zone 3. A simple setup with 7.1 in the main room is zone 2 speaker outputs to one room, then zone 3 preouts to an integrated amp with A/B speaker connections for the 2nd and 3rd rooms. Also, sometimes there can be issues playing digital source components in zones 2 and 3.

Have a look at Cambridge. They're very good for multi room/zones. 

As you can tell from my previous post, I prefer a wired sound. The SR7011 does give you a variety of wireless options with HEOS. You could just add the HEOS speakers in each room, or a HEOS amp with a pair of conventional speakers, or a HEOS link with conventional amp and speakers.
