Summary: I have some doubts about the efficacy of writing a review for a product that is discontinued and there are only a handful left in stock. If anyone is on the fence about whether to buy this or wait for another deal -- go for it.
Summary: Initially, I had trouble connecting this unit to my wired home network. Although this receiver had a DHCP -assigned address on my local network, it would not work to access the Internet despite several network and receiver power cycles. The receiver kept saying there was no Internet connection.
Pros: Great power and feature set. Fairly compact for its power rating. Nice appearance and user interface.
Cons: Did not work out of the box to access the Internet. Had to perform a complete factory reset to gain access to the Internet.
Summary: I liked everything about this receiver. I just could not use it on my 4 ohm speakers. You have to step up to the $2,500 AVR-4520CI if you have decent speakers. Everything else worked as advertised. The internet radio to the Audyssey to the video upscale.
Flexible and Complex - Not Enough Internet Radio Favorites
30 April 2014
Summary: I have had the Denon for two months and I am reasonably happy with it. It is extremely flexible with its 3 zones, including independent HDMI zones in 1 & 2. If you value the three zones, the Audyssey X32, HD Radio, and 7 channels of amps, it is great.
Summary: I was upgrading from a 6+ year old Denon AVR-3803 that lacked HDMI. I purchased more than I need as my new apartment has a deck so at some point I hope to use the mutli zone features to play audio and video up there. The audessy features are great.
Pros: Like the Audyssey speaker level automatic analyzer. Unit sounds great and functions good. AirPlay works good.
Cons: Users manual is hard to understand. Unit doesn't display the network it is using. It cost me a day calling Denon, router provider, Apple, and Crutchfield to get AirPlay to work. Each provider blamed the other, but no one asked if there was more than one network. Miss having a n outlet on the rear...
Summary: The top of the unit gets very hot after extended periods of time. I turn it on around 6am and I don't turn it off until ~9pm. Problem: I noticed that if I apply pressure to the top of the cover, when it's hot, the unit powers down.
Pros: Great unit, lots of ways to play different media. Works well with the iPad and iPhone app; wish there is one for my iMac.
Cons: Setup was difficult, owner's manual needs more description for functions
Summary: This replaced my aging Denon AVR-3803, driving my main living room 5.1 HT system with UHD TV, plus a 2nd zone on a covered patio. I upgraded the patio TV from a CRT to HD, so the 4000's 2-zone HDMI was a perfect fit. I am very experienced with AV setup, so setup was quick and easy.
Pros: Price, flexible connections, 3-zone output, quality, features
Cons: On-screen display requires processing of video signals, lacks flexibility with 2nd zone video, slow "apps"
