I think I really want the Airplay feature, which automatically eliminates the Onkyo receivers, but of course everything becomes more attractive at a certain reduced cost. Thus, when the 818 went on sale for $649, I was really itching to pull the trigger. However, now that BF/CM is over, I think this makes it a tiny bit less attractive. I really do like the higher end features, such as XT32, but perhaps I need to seriously evaluate whether these are worth the loss of Airplay.
(Yes, I know there are other apps/ways to get music to play via Airplay, or I can even buy an AppleTV to do this...)
