I am a Focal guy and love my 836v speakers and almost got the 816v. I also do home theater and stereo in the same room. I personally would get a stereo integrated with a home theater bypass to power the mains so you can hook you stereo sources directly to the integrated. The Krell S300i would be my dream toy for this scenario and would be a fantastic match with the Focals. I was recently blown away by the 807v speakers using this amplifier.
The rest depends on your budget. You could do a surround receiver with pre-outs to process and handle the other channels. I think anything beyond 5.1 is overkill unless you have a dedicated theater room.
