Sweet Spot Listening or Space Immersion?

Like many of you I have a dedicated listening room, focused on high quality, two-channel music.  My equipment and room is very much focused on delivering the best SQ to a sweet spot in the middle of my love seat.  It’s truly great!  But it can feel a bit exclusive since it is very difficult for more than two people to enjoy the benefits at the same time.

I also have a whole home audio system, recently implemented, with high quality in-ceiling speakers in several common areas, with a pair of subs in the largest area (living room/kitchen combo).  I also have good outdoor speakers on the system as well.  Because sometimes I just like to be able to wander my home and feel immersed in high quality music.

The new whole home system is built around the new Mcintosh CR106 controller, with a pair of MI128 8-channel amps; KEF CI200QR ceiling speakers, KEF KC62 subs, and KEF Ventura 6s on the patio.  I am streaming from Bluesound Nodes for now (using the CR106 DAC), and I have an MR87 tuner for nostalgia purposes.

Right now I have all the pairs in mono mode and that seems like the right approach to avoid hearing unbalanced stereo sound.  The KEFs have very good off-axis dispersion, which is good because my ceilings are not terribly high.

Anyway, anyone else doing something like this in addition to your dedicated listing room?  Any advice or tips?
