I don't get what the issue is... I have all of my sonos hooked up to a plethora of dedicated amps, home theater receivers, and distribution amps. We typically control Sonos via C4, especially with the somewhat recent EV updates that automatically puts favorites into the stations tab. We occasionally use a sonos controller to browse music in ways we can't with C4 and sometimes we use the sonos app to change the volume. I don't know that a Perfect Scenario will ever be available, but the C4, Sonos, EV solution is rather close.
