Well, only Denon and Pioneer/Elite even have Airplay.
Most AVR are LAN based, which you can then purchase a dongle.
If you give up the Airplay(and can just use a USB) you can get an Onkyo with the V-tuner(starting at the 709. The 809, still under $1000 has two USB, so you can use the rear USB for the WIFI dongle and the front USB for the Iphone/Ipad/Ipod)
