| The Bottom Line | Despite a couple of flaws, the Onkyo TX-SR504's winning combination of features and performance demonstrates that Onkyo remains a leader in the entry-level 7.1-channel A/V receiver market. | The Onkyo TX-NR609 has six HDMI inputs and lots of built-in streaming music services, but it lacks AirPlay and doesn't sound quite as good to our ears as some competitors. | The Denon AVR-1912 gets our Editors' Choice Award in the midrange AV receiver category, with built-in AirPlay, outstanding sound quality, and six HDMI inputs. | The Yamaha RX-V671 sounds excellent and supports several high-quality streaming-music services, but it lacks built-in AirPlay support. | Pioneer's VSX-1012-K is an excellent AV receiver with built-in AirPlay and top-notch sound quality, but Denon's AVR-1912 is just a little better. |
