Conclusion The time I spent with this receiver has proven once again that Denon is one of the leading manufacturers of AVRs. The one caveat I feel compelled to mention is its similarity to the lower-priced AVR-3808CI. The AVR-4308CI has a bit more power and some additional features, such as WiFi, HD Radio, and some configuration options that the AVR-3808CI lacks. Other differences include Advanced AL24 on all channels compared with AL24+ on the front right and left, two HDMI outputs (sending the same signal to two displays) instead of one, and an independent component-video output for a second zone.

If these features aren't important to you, I would look very closely at the AVR-3808CI. On the other hand, if you are looking for an AVR that has pretty much everything you might ever need in the central component of your home-entertainment system, the AVR-4308CI definitely fills the bill and gets my highest recommendation.
