As an amateur reviewer who finds himself reviewing a number of products, I am always torn as to how I should perceive the value of equipment relative to the MSRP or the price I paid. Some manufacturers use MSRP's as quick value engines in allowing retailers to show significant savings below the MSRP. This issue recently resurfaced in conjunction with a planned review of the Denon AVR891, which I recently purchased at a significant discount.

The Denon AVR891 retails for $799, putting it in what I would consider in the thick of mid-level receivers. Its primary competitors are the Onkyo TX NR708 at $899, the Pioneer VSX-1120 at $749, what I presume will be the Yamaha RX-V767, and its first cousin in the Marantz SR5005 at $799. To preface the Denon's place in this caste of receivers one must ask what should $800 buy in an AV receiver today. First and foremost, it must provide a reasonable number (greater than five) HDMI v1.4 inputs. HDMI has rapidly (and often painfully) become the single cable solution for high definition audio and video. An $800 receiver should provide not only analogue upconversion to HDMI, but also scaling and deinterlacing generally from a brand-name chip (ie Farjouda, ABT, Marvell, etc). An $800 receiver should provide flexibility in incorporating multiple zones, presence speaker configurations, and auto-calibration software. Advertised and delivered power should represent adequate muscle to push speakers at reference levels. Ipod, Internet, and Blutooth connectivity round out the modern featureset while legacy input and connectivity are rapidly fading as we move more and more to a truly digital realm.

In that space, the Denon AVR891 nicely checks most boxes. It provides six, rear-mounted HDMI v1.

JUNE 2011

In my opinion, this receiver is the Denon to buy. This review is for the buyer who wants the best bang for their buck, sticking around a couple of hundred dollars.

2012 MODELS:
I did not choose the 2012 models. AVR 1312, 1612, 1712, 1912, 2112, 2312, 3312. (the 12 in the number is the year. The first two numbers 13,16,17 represent the quality level. Example: 1312 < 1612. Better quality, more features). All 2012 models have some sort of wireless wifi ether something connectivity. If you want to controll or connect via smartphone or something like that, look at the 2012. The 2011 don't have that. I'm not ready for all that wireless stuff, however it is wave of the future so perhaps......

2011 MODELS:
Each of these models has two versions, often very similar. All of these models have HDMI 1.4a so they can do 3D, deep color, etc. Here are my quick views and their current amazon price. NOTE b/c they are 1 year old models, sometimes a better product is actually cheaper than a worse product. It just depends on the sellers.

AVR-391...$200 No no no no no no. This model does not have Denon's automatic speaker setup Audyssey. It will NOT automatically adjust your speaker levels or EQ them. You want automatic setup (at least I love it)

AVR-591...$270 5.1 set. avr 1611 is better for only 10 dollars more. no brainer
AVR-1611...$280 7.1 set. 10 dollars more than avr 591 no brainer 75 watts per channel
AVR-791... $420 The 791 and 1911 are a step up b/c they are 90W per channel and have video scaling. These will upscale your low res content into 1080p. The 791 and 1911 are basically the same.
AVR-1911.. $400 Same system as 791 but 1911 has HD radio and zone 2 preouts and is cheaper.

Verified Purchase
The Denon AVR891 is a very very good AV receiver and has a vast array of amazing features. It is also an outstanding value. I purchased it primarily because of the overall excellent sound quality, Audessey room equalization feature and Denon's reputation for quality. I was not disappointed. I have a unusually shaped room and this has led to a lot of wasted time trying various speaker locations over the years. To set up Audessey I followed the simple instructions and speakers were matched to the room easily and quickly. Tips: Don't position the microphone less than a foot of soft surfaces. Attach the microphone with a rubber band to a yardstick and attach the yardstick to the tripod top using a spring clamp. Allows you to position the microphone at seated ear level.

Thoughts on features that are important to me: The remote control is mostly logical but is not illuminated. The Surround Simulation button doesn't remember it's last setting forcing you to cycle through all choices to select the desired mode but since the receiver automatically selects the proper surround mode, this is a minor but annoying bug. Some, but not all, buttons glow in the dark. I especially like the 3 Quick Select buttons. This make the receiver much more family friendly. The overlay on-screen menu when using the HDMI output is very good. Lower priced Denon receivers' menus do not use the overlay type menu. The equivalent front panel menu is just barely adequate as the details of some less-important menu choices do not display.

I like the lighted front panel display indicators that show the present surround mode, input signal configuration and speaker configuration. With some practice they can be recognized from a distance.
