Conclusion: The Denon AVR-1613 is a capable home theater receiver, with five channels of clean power and comprehensive iPod and AirPlay integration, but it could use some refinements.
Pros: Sleek front panel. Clean, powerful sound quality. iPod and AirPlay integration works well. Useful front-panel inputs including five HDMI inputs with video switching. Native Pandora and SiriusXM support.
Cons: Buggy iPod connectivity. Networking via wired Ethernet only. USB port doesn't work with iPads?just iPhones and iPods. Rudimentary on-screen graphics look awful. No HD Radio or AM tuner. Stubborn remote. Denon's iOS app needs a rethink.
