Denon AVR-791 7.1 Channel A/V Home Theater Multi-Source / Multi-Zone Receiver with HDMI 1.4a supporting 1080p and 3D (Black)
Product Description
The new AVR-791 is packed with technology and features making it the clear choice for value oriented consumers looking for exceptional performance. Each of its 7-amplifier channels produce 90-watts of power, delivering detail and dynamics to music and movie soundtracks. They can be configured for 7.1 channel surround sound, or drive a 5.1 channel system in the main room and power a pair of speakers in a second “zone”. It’s equipped with 1080p and 3D (all formats) compatible HDMI 1.4a Repeating technology, delivering both audio and video to your HDTV with single HDMI cable. This HDMI connectivity supports the latest generation surround sound formats available on Blu-ray disc, including Dolby TrueHD and DD+, dts-HD and dts-HR. Also included is Dolby Laboratories new Pro Logic IIz Matrix decoding featuring front height effects channels that expands front soundstage. The AVR-791 boasts a number of Audyssey technologies. Advanced Audyssey MultEQ analyzes a speaker systems interaction with room acoustics, and then delivers custom tailored correction processing to optimize clarity and tonal balance throughout the listening space. Audyssey Dynamic Volume is an automatic volume-leveling system that tracks audio dynamics to eliminate the irritating volume swings between TV shows and commercials. Audyssey Dynamic EQ is also on board to ensure rich bass and smooth tonal balance at low volume listening levels. In addition to enhanced HDMI 1.4a repeating (4 in, 1 out), the AVR-791 is the least expensive receiver in the Denon lineup to feature 1080p i/p conversion, analog to HDMI upscaling and HDMI to HDMI scaling. Video conversion is accomplished using a premium Anchor Bay Technologies chip set featuring 10-bit processing. The AVR-791 also features 2 component video inputs, seven analog inputs, and multi-zone / multi-source capability. A front-panel USB input allows quick and easy connection for iPod/iPhone, Flash Drives and HDD with command and control functionality.

There are three $500 receivers to consider, if you're buying one in 2010 - Onkyo TX-SR608, Pioneer VSX-1020-K and this one. All three feature the latest HDMI 1.4, which is necessary for 3D signals. Here's how they compare:-The Onkyo is the most powerful in terms of real world performance, followed by the Denon and finally the Pioneer. All three perform at par for normal listening volumes, but the Onkyo can handle very high volumes the best, while the Pioneer runs out of breath-The Denon has Audyssey Multi-Eq, which automatically calibrates the receiver for use in your room (a mic is provided). The Onkyo has a similar but less versatile Audyssey 2EQ. Pioneer has its own system called MCACC which also works well, but Audyssey may be slightly better.-All three can upconvert analog sources via HDMI - hence you'll only need one HDMI cable to connect to the TV. The 1.4 spec supports an audio return channel, so the TV's sound can be output to the receiver without extra cables. The Pioneer and Denon use the excellent Anchor Bay chipset, while the Onkyo uses the slightly inferior Faroudja DCDi chipset for video processing.-The Pioneer and the Denon have a front USB input where you can connect your iPod directly. You can browse playlists etc using the receiver's remote via the onscreen display. Since this is a digital connection, the sound quality is excellent - while the iPod can be connected to the Onkyo via an analog cable, it does not sound as good and cannot be navigated using the remote.-The Denon offers an equal variety of inputs as the other two, but has fewer of them - eg, one optical input vs 2 for Pioneer and Onkyo- The Pioneer's iPhone app is just a gimmick and of limited utility - I would prefer using the main remote.Overall, I decided to purchase the Denon since it has Audyssey MultiEQ and adequate power (unlike the Pioneer) as well as excellent video processing and iPod connectivity (unlike the Onkyo). I have been using it for about a week and am very pleased with the level of performance offered.Update on December 3, 2010: The receiver continues to perform well and I have no new complaints. However, I have noticed that both Pioneer VSX-1120-K and Onkyo TX-NR708 are available for ~$500, while discounts on this and other Denon receivers are marginal (here on Amazon). Hence, both those higher spec'd receivers now represent better value than the AVR-791/1911, if you're looking to spend ~$500 on a receiver. Also, the Onkyo TX-SR608 and Pioneer VSX-1020-K are now available for ~$350 and hence have become more compelling alternatives to this receiver.

This works much better than my old Yamaha RX-V661 receiver. The key features I liked were:* Audyssey Dynamic Volume for automatically turning the volume down for commercials and up for quiet scenes so that you don't have to keep your finger on the remote when trying to keep the TV commercial volume below a certain level. This is a key selling point in my opinion! You can configure it to 4 settings depending on how dynamic you want it. Just like the Starbucks style of sizing, instead of small, medium and large, you have Off, Day, Evening and Night in the menu. Day compensates the volume the least, and the Night compensates the volume the most. The Evening setting seems fine to me.* When you first configure it, it configures the sound levels specific to your room configuration for up to 6 listening points with an included microphone. It detects the frequency cross over for your speakers and speaker specific volume levels for optimal listening. It can also detect miswired speakers.* 4 HDMI input ports and 1 HDMI output port.* iPod USB connection. You can use the remote to control the song selection.* Delete unused inputs for easily skipping over unused inputs.* Analog video conversion to HDMI. This is good for playing the Wii or other older cable inputs without switching TV inputs.* It doesn't have an excess abundance of inputs. So it's a little easier to wire up.* You can rename the inputs to make it easier for everyone in the family to remember.* You can configure which inputs are used for each video/sound combination. This is probably why there are fewer inputs. For simple configurations, the defaults will be good enough.* If you don't like the default brightness on the display, you can turn it down in the menu. This is good for adjusting the display appropriate for the normal room light level.* Standby mode is 0.1 watts, but I wonder why it doesn't have the Energy Star logo on it.* Total harmonic distortion is 0.08%.Here are the things I disliked:* If you have a standard universal remote, the typical power button won't work because it uses discrete off and on buttons instead instead of a single power button. Using a Harmony universal remote from Logitech will solve that problem.* The volume button is a little sensitive. The speed for changing the volume is a little fast for me, but with Audyssey Dynamic Volume, you don't need to change it as much.* When I first started to use it, it really messed with the TV's black levels. It seems that changing the video mode from auto or game to movie resolved that problem.* For a little less money I could have bought the less powerful Denon AVR-591 for most of the same functionality. I'm undecided on whether the price difference was worth it, but I'm still very happy with the new AVR-791 receiver.

The audio and video performance of the Denon AVR-791 is exceptionally good. The amp has plenty of power, good audio processing features, a very clean sound, and a good balance of audio and video input/output formats (I really need one more component analog input, and I'd like one more S-Video input, but didn't want to spend the $$ for the upgrade to the AVR-891). There were two specific features that were a "must have" for me: upsampling of analog inputs to HDMI 1080P, and compatibility with the newest 3D signal formats (to go with my new Samsung 3D Blu-Ray player and TV). The video upsampling is top notch - running a standard def DVD from my old Pioneer player (using the upsampling in the Denon) looks better than playing the same DVD back in my new Samsung Blu-Ray player (using the Blu-Ray's upsampling to 1080P). I did the tests using standard off the shelf movies, as well as the "Microsoft Hardware Compatibility Labs" DVD Test Disk.The Audyssey auto setup works remarkably well and gets all the audio settings "close enough". I was able to get it to sound a little better with a little fine tuning, but most people should be happy with the auto setup (I am using the Definitive Technologies ProCinema 600 speakers, which are a great match for this amp).My biggest complaint is with the on-screen menus and the remote control. The on-screen menus are horrible, with standard definition black/white text that looks incredibly ugly in 1080P. The menu navigation in general seems like it was bodged together without much thought. The remote control has the opposite problem - it is so over-engineered and it has so many buttons and shift functions that it is impossible to figure out. The text over the buttons ("secondary" functions) is medium grey on black - impossible to read even in bright light, much less the dim lighting that you find in any media room. And the "primary" functions are printed way too large on the small buttons, so the text is cramped and illegible. Half the buttons are completely useless, they should be removed and all the other buttons should be much larger with more legible text.I was tempted to give the AVR-791 a three star rating because of the UI issues, but they did get all the important stuff right (it really is a great amp with top notch audio and video quality) so I went with four stars.UPDATE: After using the AVR-791 for a few more weeks, there is one more frustrating issue that has cropped up. The amp has plenty of analog inputs, but they can not be mapped to different video inputs. The only audio inputs that are "mappable" are the single digital coax and the single digital optical. So to connect my PC running Media Center, I can not map any of the myriad of unused analog inputs to the HDMI input that my PC is hooked to. My only option was to move my secondary DVD player to the optical audio input, so I can use the coax input for my PC. However, my basic sound card didn't have an SP/DIF output, so I was forced to get a new sound card (which, admittedly, provides much better audio quality - but the issue is that the analog inputs aren't mappable. I'm sure the hardware is capable of doing this, but the bone-headed software in this amp is very unappealing.)
