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. Another side note, if you are used to watching movies via AirPlay, you will still need Apple TV. The Airplay and DLNA features are audio only. So pretty pointless additions, imho.
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. But I have found that the manual is not detailed enough, it is extremely complex and the Audyssey makes the audio too bright.
Summary: First I have to say I like Denon products and this is my second Denon receiver. Sounds and works great. My problem is that it will only allow you to play 9.2 surround sound. I thought it could do 11.2, so I bought 11 speakers. I have 7 speakers plugged into this unit, and then four more plugged into my old Denon via the preouts from this unit and the multi channel inputs on my old one.
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 panel.
Summary: This is a replacement for a Denon AVR-2310CI. The 2310CI is very complicated and has an excessive amount of remote control buttons and functions in comparison to the X4000. The X4000 on the other hand is very evolved from the predecessor 2310CI. The X4000 has improved and refined A/V processing power, and presents its features in an easy to use straightforward manner. The X4000 is what I imagined a 21st century receiver to be.
Pros: Lots of great features, easy to set up. Excellent cost/value to feature set ratio. Video processing is on par with great audio performance. This is a great AVR. If you're on the fence about this purchase, just buy it, you won't regret the purchase.
Cons: No printed instruction manual; you'll have to read the manual on your computer or PDA. The next task for improvement should be in developing a much better I-Pad/PDA remote control app for these AVR receivers. The latest generation of apps are an improvement from past versions, though they still have a way to go. I would be OK with paying for a really great app to control and set the X4000. No 4 ohm output; you'll have to buy Denon's top of the line receiver to get thi...
Better audio than I thought. Great features as I expected. Not finicky.

Summary: I was using an Emotiva UMC-200 with an XPA-5 external amp to drive a 5.2 channel setup with Ascend Acoustic 340s across the front with HTM-200s in the rear. My UMC-200 had a hardware failure and I bought the X4000 to stand in for the UMC while it was getting repaired. The X4000 is absolutely great. The UMC can be finicky when driven with my HTPC running mythtv.
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. Sound much better than what I came up with doing the calibration manually. One sour point is the unit recently bricked after a firmware upgrade. I got a DSP error during the upgrade.
Summary: Upgraded from Denon AVR-3808 to AVR-X4000 and no regrets. XT32 , SubEQ, LFC are worthy upgrades. Controlling AVR from iPad/iphone is very simple and no need to have the TV switched on to see what AVR is playing (like Pandora/Internet radio/USB etc). Including album cover you can see what AVR is playing right in your tablet/phone. Airplay is huge plus. At first I was skeptical about this AVR due to its weight and power ratings compared to AVR-3808.
