I just purchased this item and am thrilled with the difference in sound when compared with my older Onkyo TX SR705 or even my Yamaha RX-V1400. A few months ago I was just looking for better sound and tried to join forces by using the pre-amp from my Onkyo with the stronger Yamaha amplifier. There was some improvement, however I still felt the need for an upgrade. My wife just shaked her head and said another one of those black boxes for your collection, my justification: it is Christmas time darling.

After reading a large number of reviews even from different countries, I came down to Onkyo's TX-NR808 and this model. For sure Onkyo provides a great value for the money, mainly once prices start dropping, however after reading multiple reviews I had the impression that Denon's AVR-991/3311 would deliver the warmer and more detailed soundstage that I was looking for.

Denon's Audyssey setup was a breeze, menus are nice and easy to understand. It was the first time ever that I haven't had to adjust the settings after auto calibration, neither YPAO nor the older Audyssey on my Onkyo could deliver such an accurate calibration.
Once calibrated I turned on Pandora and my jaw dropped, I didn't know my B&W speakers and Velodyne subwoofer could deliver such crisp clear highs, and thight and precise lows, they always sounded great, but this was like if I had just installed a brand new HT system all together, I never thought this new Denon would make such a difference. My friends were always impressed with the sound in my HT, but this is awesome, it fills the room with incredible precision remaining pleasant even when playing loud or during movies action scenes.

Rather than parrot the expert reviews that are available with a simple web search, I will just say that I like it better than the Onkyo SR805 it replaced.

On my equipment, It sounds appropriate for the price point. It also works with all of the my equipment - including 3D. It hasn't broken yet, seems to stream Pandora ok, and has a handy (albeit slightly clunky) web interface that lets you setup and manage the unit. I have never used the iPod dock (I use Airport Expresses), so cant say anything to that interface.

Very satisfied with the purchase.

I'm by no means an expert, but I am somewhat used to Denon products, having owned/used them for a while. I mention this because, if you're new to Denon, or aren't good at deciphering detailed instructions, prepare yourself for a new level of tech frustration if you venture beyond the basics.

The basic, plug-and-play setup is pretty easy and quick, and should work nicely for a standard config and standard speaker placement. My setup was a bit more complicated, mainly because the speaker placement is non-symmetrical, which caused the auto Audessy calibration to overcompensate the various output levels and crossover frequencies. It did it's job the best it could, but the final product -- the acual playback sound -- was way off and I had to resort to manual calibration with a sound meter. Once everythng was set, the sound quality is second to none! Other pros and cons so far:


Apple AirPlay - dowloaded the $49 upgrade from Denon and can now stream & control music playback directly from our ipod touch and PC. The best feature about AirPlay is that it automatically powers on the 991 ans switches it to the correct input/output as soon as you select a song. Definitely a nice feature for others in the household.

Networked - you need an ethernet cable, but once set up, there are many useful apps and features the networking brings to bear. Like, full configuration control of all settings from a web browser, streaming music & photo services, etc.


Terrible remote - tiny buttons, most with illegible captions. In one word: pathetic.

Display - almost as bad as the remote. Unless you are less than 2-feet away, it's almost impossible to read the mumbo-jumbo of data that is presented on the display at any given time.

I have been a dedicated Marantz user for many moons. Bought the first Dolby Digital receiver they offered. Upgraded to the 800 years later and had no problems with that one. Loved the sound quality. There is something about those Marantz units' sound that is just...right.

But when HDMI came along, Marantz started to go off the rails. Upgraded to a SR8001 and was blown away by the sound. Marantz all the way...but even more so. Three months later the thing went into shutdown and wouldn't come out. Had it repaired under warranty and got another three months out of it; had it repaired again. Same story. The fourth time the ol' Marantz bit the dust, I was finished with it and went to its successor, the 8002. Marantz couldn't have screwed up two receivers in a row, could they?

Two months later I was getting the thing repaired. Bottom line: I have never owned a Marantz HDMI receiver that was anything like reliable. I bought an inexpensive Pioneer receiver with all the iPhone whizbangery to fill the gap while I searched for a better solution.

So I turned to Marantz' sister company Denon. If I can't have the Marantz sound, I can come close with Denon. Fact is, the more computer chips are hung on these things, the more basic sound engineering must be sacrificed to meet the price point. I had almost given up looking for the big-boy Marantz sound in a sub-$1000 receiver when I decided to try the 991 from Denon.

It's only slightly less powerful than its immediate big brother, and doesn't really sound all that different from the other two powerhouses further up the range. Bass management is competent, meaning if you have a good sub and good speakers, this unit has the facilities to drive them correctly. This is something that unfortunately the little Pioneer cannot do.
