Product Description

Product Description

Performance, technology and affordability are the hallmarks of the AVR-591. A powerful 5 channel x 75W amplifier section delivers detail and dynamics to music and movie soundtracks. It’s equipped with HDMI 1.4a Repeating technology, compatible with 1080p (24fps) and 3D (all formats) allowing delivery of both audio and video to your HDTV with single HDMI cable. 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 to dramatically increase the front soundstage for the ultimate surround sound experience. The AVR-591 boasts a number of Audyssey technologies. Advanced Audyssey MultEQ analyzes a speaker systems interaction with the listening room at up to six measurement points (microphone included), and then automatically corrects the response to optimize clarity and tonal balance. 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-591 features, analog to HDMI conversion (480i to 480p) and five analog inputs. A front-panel audio/video input allows quick and easy connection of camcorders and game systems. System setup is simplified by a new, enhanced icon-based on-screen display that is delivered over HDMI. You can also connect and control your iPod/touch or iPhone using one of Denon’s available iPod/iPhone docks, which provides on-screen artist, album and song information. When connecting iPod and other MP3 players, the AVR-591 features Denon’s exclusive Compressed Audio Restorer to improve sound quality and dynamics.

Packed with great features that assures a superb 5.1-channel surround sound experience, the Denon AVR-591 supports Dolby TrueHD and DTS-HD Master Audio decoding and it includes the latest HDMI 1.4a technology, which provides for 3D pass-through capabilities to your HDTV (broadcast and Blu-ray). It also features Dolby Pro Logic IIz, a technology that adds a vertical dimension at the front for a more exciting surround sound experience. Additionally, the AVR-591 features Denon's Audyssey MultEQ and AutoSetup capabilities, and it includes a tower type microphone for more accurate measuring.

With built-in separate internal amplifiers to power each channel independently, this feature allows you to enjoy the same high power output capability per channel, giving a balanced and truly high-impact surround-sound environment.

I've been listening to a great podcast about audio and video technologies and found that this was the least expensive of the Denon models that offered the Audyssey MultiEQ room equalization technology. I don't have a large room for my home theater. Actually it's a little out of the ordinary in that I have the orientation in a non-ideal setup. I wasn't sure how this room equalization technology would work in my setup and I wasn't sure that I would get incredible sound from a unit this inexpensive but I decided to try it anyway. I had a Yamaha receiver previously that had a proprietary calibration setting with a microphone for automatic setup. My experience with that wasn't very good. Assuming that I read the instructions correctly, which I believe I did, the result ended up turning off my sub completely. I got it tweaked fairly well after playing with it for awhile but, needless to say, I was a little skeptical about the Audyssey setup because of this experience. The reason I decided to try it out anyway was because of the difference between how Audyssey and other companies do this automatic setup process. The Audyssey calibration, for lack of time, is much more complex, complete and precise. I am completely blown away at the difference this has made in the complete sound of my system - both movies and music. I have a pretty good collection of DVD-Audio surround sound music discs and what a difference the new receiver with the Audyssey MultiEQ calibration technology has made. I run Polk Audio RM85 satellite speakers and a Polk Audio PSW110 10-inch active sub through this receiver and the combination is perfect for my room environment and my listening preferences. I highly recomment this receiver

I bought the Denon AVR-591 to simplify my home-theatre setup and so far it's working perfectly. The Quick Select buttons also power-on the unit and so my preschool kids are able to press just one button ('Quick Select 1') and get the TV to work. I was also able to reprogram our Logitech Harmony universal remote so that it sends fewer commands.

I also appreciate the analog-to-digital video conversion (the kid's composite-video Click Start game is converted to HDMI) as it allows me to leave the TV on one input and never need to change it; this also makes the system simpler and more predictable.

The Denon configuration menus are relatively easy to use though I do have to keep the manual around to help me find some of the 'advanced' settings. You are required to run their Audessey speaker-test before you can adjust a lot of things, e.g. speaker levels (the center speaker needs to be louder), or 'Night Mode' volume compression.

The one problem I've had is that I sometimes lose the audio signal/sync, e.g. when I pause my Tivo S3. Switching to/from another input or program always fixes it, though, so I'm only knocking 1 'star' off my score for the unit: I give it 4 Stars.

Talk about a modern feature set. Whether or not firmware will upgrade HDMI 1.3 or not on your existing system, choosing a system with an HDMI 1.4 repeater for all inputs is a good idea and this unit certainly has the skill to do so. Let's jump right into the pros and cons of the unit because it certainly isn't perfect. As a long-time user of Pioneer/Sony ES/Denon receivers, I think Denon's done a fair number of things pretty well.

- HDMI on-screen Audyssey eq and assignment functions. This helps a lot because the small screen on the unit won't suffice. Using the same technology as the Alpine imprint system (which works great in the car), you can tune to your environment. Not unique, but well done all the same
- HDMI repeater for all inputs. This is a pro and con, read more to find out why.
- HDMI 1.4 for future 3D capability. Plan for that future 3D screen (Especially good if you already own a PS3)
- Denon reputation and audio quality compared to similar priced Pioneer/Sony units
- Price, very reasonable for the feature set

- Power rated at 6 ohms, which, as you might expect means that it doesn't have quite the juice of its rivals (70w/channel at 8ohm). I definitely notice the lack of power with many inputs more than my previous Sony unit
- HDMI repeater is not particularly good with component inputs. Using the component inputs on the Wii, direct connection to the TV is vastly superior visually to the HDMI conversion the Denon performs
- Relatively steep learning curve. You will find a little frustration with some of the advanced functions as the manual is a bit tedious. This is par for the course though, so nothing specific to Denon.

The wife and I bought this receiver mainly to simplify our home theater setup by having all AV inputs fed into the receiver via HDMI with only one HDMI output to our 50-inch Panasonic LCD HD TV, and I must say sound and picture quality from all input sources of our home theater system are first rate with the Denon AVR 591. This is our second Denon AVR and it has the expected Denon high quality and also the usual Denon dictionary sized installation manual that is necessary because even the lower-end Denon AVRs are very feature rich. I must however complement Denon for dividing the AVR 591 owner install manual into "simple", "basic", and "advanced" sections to make it easier for the "electronically challenged" (I include myself in that category) to get the AVR up and running quickly with minimum frustration. Denon is also to be praised for choosing some years ago to build into their AVR receivers the wonderful and very functional and easy to use automatic microphone-based speaker setup system by Audyssey -- and I highly recommend to one and all use of this Denon setup feature because it is truly uncanny in how well it automatically handles the usually very complicated task of setting up and fine tuning a 5.1 or 7.1 home theater speaker system.

The Denon AVR 591 is a great receiver/switcher for a home theater system arrayed within a relatively small listening/viewing area and one that uses smaller less power-hungry speakers.
