What speakers do you have? TBH you can't really go wrong with any of the current offerings from Denon, Yamaha or Onkyo for example. I believe the latest Yamahas offer Airplay if that interests you. Prior to that only Denon, Marantz and Pioneer offered Airplay. Onkyo have Spotify as a feature. Obviously study the specs to make sure it has the right number of connections as a lot of the latest kit have trimmed their spdif and analogue inputs in favour of HDMI.
