AirPlay is quite good on my Cambridge Audio CXN 100. I rate it as just a notch below CD. Chromecast is better still but you need an Android device.
They both sound much better than Bluetooth
Air Play
Air Play transmission is often put down as having inferior SQ. I find that with using my Aurender 200 streamer it sounds quite good and there is very little loss of quality compared to files played from Qobuz and other apps running through the Aurender streamer.
