Air play is flawless ... So good infact that my socks actually blew off my feet within seconds of using it...
We air played a movie on the iPad from bed, to speakers "b" and when we were done switched off the amp (in the other room via the app) and said good night to HAL!
It's easy, functional and flawless... Unlike the myriad of settings on this amp lol
I did find DRC controll

and bass and treble controll and I suppose the rest will be found in time, with it being new and not many people having it it's hard to get answers for questions, but after a few weeks I've found thr answers to most ofvmy questions my self.
I highly recommend this amp, the sound is awesome and it's and amazing stereo amp as well as AVR..
It's almost exactly the same spect as the 1021 and infact, other than. Few extra inputs I see no difference what so ever between the 2!
Buy it, you won't regret it... Well you will... Wehrn you can't find a setting and have to wait 2 weeks for an answer... But then you'll love it again
