Multi room with Cambridge Air 200 and Apple TV

I paired 2 Cambridge air 200 with an Apple TV (correction of 145 ms. for sync) and works wonderfully in an open Space of approx 80 m2. Easy to set-up, simple to handle, no fancy, useless gimmicks: just focus on sound. A much cheaper and versatile option than the all in one : Sonos, Musicast that do not give flexibility in building multi-room with different equipments. Whaale app allows to blend multi brand materials either for cost (current january sale offer interesting opportinities for previous generation equipment, as long they have AirPlay), or quality or size or design reasons.
Highly recommanded.
