Conclusion: Yes, the comparison between the new Marantz and Denon lines is apt - they share a lot of the same features such as Apple AirPlay, 3D pass-through, 4k upscaling, Audyssey MultEQ XT, and more. But lots of receivers have these features. What distinguishes the Marantz offerings from the rest of the crowd, is the number and types of connections. These are receivers for those that aren't first time buyers. These are for those that might have (or plan on having) external amps.
