I have the Marantz NR1506, and though I do not own even a single apple device
, the sound quality and features are totally worth the money, esp. the sound quality. I have also used the Denon AVR X520BT, and in the price range I personally found it better than the Pioneers. If you are considering the VSX 531 for about 34K, then Denon for 37K, is a much better deal in my opinion, purely in terms of sound as the features are pretty similar.
