The 4700 is not the only Denon model, but you know that.
The previous model...the 4500 is an option, the 3600 another, and we don't know if the 6700 follows the 4700's path, not until we know all the differences in how the parts are put together and how it measures. The schematics are always a good start for audio engineering point of view, then the measurements, and finally a doze of music listening with ease of setup. Methinks. The features? The ones you can use you personally, not necessarily the features others use. No two AVR owners use their receivers exactly the same with exactly the same components connected and the jacks offered.
* I would love to ask Denon why they are still using composite and component video jacks on their receivers? Is it because they sell more of them?
