Conclusion: On the surface, the Denon AVR-4520CI makes a pretty strong case for itself as a flagship receiver. Its combination of relevant features, consistent and reliable operation, and a straightforward user interface makes interacting with it on a daily basis a fairly pleasurable task. Its multi-room audio/video capabilities would also serve a whole-home, networked system well.
