You lost me.
I didn't get whether you are switching sources for the M22's or not.
Here's what I did:
Mirage in-walls in the kitchen and AV123 OD100's outside. Both purchased before either the Algonquin or T Series were available.
I installed a PartsExpress Dayton volume knob in both the kitchen and outside (in a weather-resistant enclosure under the gazebo roof). You can also add an impedance-matching wall-plate (which I did not need to do); that step would enable you to power both zones with 2 channels and transfer the on/off and attenuation functions to the listening location.
Powered by an old Adcom power amp that sends the same signal to both the A and B speakers. Even if I forget to turn off one of the amp zones at the amp, users can attenuate the volume at the speakers. Pretty low tech, but works for me.
The Tweakcityaudio Gizmo amp might be an option for the kitchen amp. It saves you space, but not money. Not sure about running a parallel load, though.
