A:Answer You can connect your Bose speakers easily to the Denon. If you have a subwoofer it can also be accommodated. Without one, the amp seems like overkill.
The Denon does support Airplay (audio only, I think) , but requires Apple devices and Wifi . The receiver manual could be a little clearer about setting this up. However, the Denon customer help site has a simpler explanation.
I have not tried Airplay but use an Apple TV box ($180) connected to the media option through one of the HDMI ports. This gives me some streaming video too.
