Least expensive unit with Audyssey MultiEQ room correction July 2 2010
By Jeremy Sampsell - Published on Amazon.com
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

Does everything I expected May 30 2010
By A. Tovar - Published on Amazon.com
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.

Not perfect, but a good entry-level 3D platform July 11 2010
By C. Covalucci - Published on Amazon.com

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.

Pros:
- 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

Cons:
- 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.

Denon quality for a reasonable price. Jan. 2 2011
By R. Olsen - Published on Amazon.com
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. However, due to the relatively low power output of this nonetheless very high quality receiver I would not personally suggest using it with large power sucking speakers and would further suggest it is best suited for a listening/viewing distance of no more than about 10-12 feet, otherwise you will find a volume setting of 90% of max is often needed to get decent sound out of a 5.1 home theater system. We use the Denon AVR 591 with smaller and very efficient and high-quality 8 ohm NHT bookshelf speakers and that works great in our small condo living room. Also be aware that while the Denon AVR 591 is advertised on the box and in newpaper ads by the big-box retail sellers as providing 120 watts of power per channel with a five speaker system, this power rating is misleading because it's the power output only when 4 ohm speakers are used and not the 8 ohm speakers that most of us actually use in real life. It actually only provides 75 watts per channel with a five-channel speaker setup using 8 ohm speakers, and that is how Denon rates the AVR 591 power output on their website vs the 4-6 ohm speaker power rating of 600 total watts (120 watts per channel) used by retail advertisers (although Denon strangely uses the 600 watt number on the shipping box for the AVR 591 vs the more standard 75 watt per channel specification number for 8 ohm speakers that they show on their website). If it were not for this strange and very misleading power output specification I would have given this hig-quality and feature-rich Denon product a five-star rating.

Very good value, some minor words of caution Aug. 25 2010
By Mickey B. - Published on Amazon.com
Verified Purchase
I won't spend too much time repeating what the other reviewers have said, but I agree this product seems a very good value considering the price and features. Note that my setup is all HDMI, run through the receiver and out to the TV.

A few words of caution that are not necessarily a fault of the receiver but can affect your overall experience:

1. Lip sync was a problem at first. There is an option to automatically handle it with the TV, but apparently my TV does not have this feature. I had to manually delay the audio about 40 ms to get it right (and it drove me crazy until I finally got the right delay).
2. I use the rocketfish wireless surround kit for the rear speakers. There is a delay inherent to that product, and after running Audyssey I had to manually change the distance to the rear speakers - due to the delay it calculated they were 28 feet away, instead of about 8. Easy fix, however just make sure you double-check.
3. I started playing with the surround features while playing Xbox360, and noticed it stopped outputting Dolby 5.1 and was only recognizing 2 channels of input. After driving myself crazy trying to fix it through the menu options (which are not always intuitive), I went into the Xbox settings and de-selected Dolby Digital, then re-selected it. This fixed it but again, other Xbox users take note. It took me days to figure it out and completely by accident.
4. After running Audyssey the subwoofer was way too loud, at least for an apartment. Easy fix, just turned the sub down.

Overall I recommend this product, and suggest that once you do the initial setup don't fiddle with it!
