Recommended AV receiver (with good connectivity/networking) for Cambridge Audio Minx set-up

Hi there I am looking to set up my first proper home cinema system. I have a decent 42-inch Panasonic plasma, am planning to buy the CA Minx 5.1 speakers (for both sound quality and wife-friendliness reasons!) but am struggling to find a decent receiver. They all seem to have drawbacks - reliability, lack of wifi or something else. Budget is flexible (I'd up it if there was a really good receiver which was worth the investment) but I was hoping to spend about £400-£600. From my research, the ones I was thinking about were PIONEER VSX-1020-K, SONY DN1030, DENON AVR-1913, ONKYO TX-NR616 AND PIONNER ELITE VSX-40. I want to be able to stream internet radio, connect my iTunes from my NAS drive and generally be future-proof in terms of number of HDMI inputs. I have Apple TV in case that helps. Help please!
