The Denon AVR 391 does not have a lot of bells and whistles, but if you are looking for a high quality receiver at a reasonable price, you could do a lot worse. This unit has four HDMI ports on the back...and that's about it. It doesn't have any component hookups. It has a few composite connections for audio and video. It also has a few digital audio connections (coaxial and optical). It does not upconvert analog video to 1080p. If you can live without a few of these features you will likely be impressed with what you do get. It decodes pretty much all of the current HD audio codecs. Blu-ray movies look and sound phenomenal through this receiver. I have my PS3 and Xbox360 hooked up to it and my games sound incredible. I even have my Wii's audio passing through this receiver and it sounds good too. I'm not really in to 3D, but this receiver supports HDMI 1.4a, so if you've got a 3D compatible player and TV you're good to go. Generally speaking, it's very simple to hook up and operate. It does not have on screen menus, but configuring the speakers is pretty easy using the units display (it all has to be done manually). The remote isn't great, but it's not bad either. It's fairly intuitive and easy to read. It's not backlit or anything like that. It'll control your iPod via a Denon dock though (which actually does have an on screen menu, but it's not much to look at). If you're just interested in getting the basics (audio and video), then this receiver is a good way to go, especially if all of your components are HDMI.

I've had the 391 for a couple of days now and am very impressed. While I did consider the 591 and other models in the current Denon line, I've been on a "simplicty" kick here recently and have been seeking out high quality components that give me the features I really want without the added cost and complications of the features that I do not want.

My main pre-purchase concern was that a receiver at this price point, even from Denon, would sound underpowered and thin. This is definitely not the case. Its powering 5 Polk speakers (TSi200 fronts, Tsi100 surrounds, CS10 center along with a HSU sub) with no problem. The sound is strong and clear with room to spare. Having configured other Denon receivers in the past, manual setup was a breeze. The 391 has more than enough HDMI and other inputs to meet my current and future needs. The FM tuner seems to be especially strong.

Five years ago, I couldn't have imagined a receiver with these features and of this quality for $250.00. Denon has an entry level winner here; strongly recommended for those seeking excellent 5.1 audio at this price point.

I purchased this receiver to compliment my new 55" LED LCD. I previously owned a 12 year old Kenwood. However, I wanted to get something that enjoyed all the new audio standards and made use of HDMI inputs & switching.

When I received the unit I had not yet completed the install on my speakers. I only had 3.1 setup but feel that this was a good gauge of sound quality regardless. My setup is as follows.

HDMI U-verse Box
HDMI Sony Blu-Ray
Optical Cable from TV for netflix and other streaming content(since there is no ARC)

First of all the sound quality was amazing. We watched the 2 extended fight scenes in Iron Man 2 on Blu-ray and it it was crystal clear and great. Sound was amazing and panned from left to right great and the dialog from the center channel was very clear and did not suffer from mumbling.

The downside was I couldn't tell if the unit was using TruHD or Master Audio HD. There was no clear display and though I thought the unit would be able to autoswitch inputs (like my tv and previous HDMI switch could) I had to manually switch to BD/DVD.

I also could not figure out how a $250 dollar unit didn't have a standby mode that allowed video and audio passthru... I had to turn the unit on each time I wanted to watch TV which in some cases is not the best option.

Another small (well "large") point to make is that the unit is almost 7 inches tall which means that you're going to need some specialized storage for it, or have something with adjustable shelves. This means it was almost 2 inches taller than my older Kenwood unit and I found myself having to put it on top of my media table. Of course a huge black brick is not the most attractive item, so having this on display was not a bonus.

This is the best Entry level AVR out there in the market and the first one from Denon in 2010 model line-up and I have to say that this beast is packed with all the essential feature, an entry-level AVR must have. Not all of us need a 8.1 channel Surround Sound system, but this 5.1 channel Surround Sound system can be extended to include two addition preouts for Surround Back channels at an amazing price point. This AVR sports four HDMI 1.4a (with 3D support) inputs plus it has built-in decoders for DTS-HD Master and Dolby True HD. Among all the feature, this AVR possess, the most attractive one is the inclusion of fully discrete amps for each of the five channels to produce equal quality sound. This is a huge plus at this price point. Others features like front panel controls for ipod connectivity and Dolby Pro Logic IIx, which provides Music, Cinema and Game modes, all of them make this AVR the best out there in its line. Highly recommended for those who just need an entry-level, affordable AVR, but also don't wanna compromise on any of these feature listed above.
-fully discrete amps
-DTS-HD Master and Dolby True HD support
-Two Additional Preouts (Left & Right) for Surround Back channels support.
-four HDMI 1.4a support (with 3D Ready and Ethernet channel)
-Very Affordable, entry-level, sub $200 price point.
-Sound quality is almost at par with any mid-level Denon AVR.
-NonIntuitive remote controls (separate power on/off button, flimsy volume buttons are just a few things to start with. I wonder when Denon will learn how to make intuitive RCs from Yamaha, Samsung and Sony etc)
-Big and bulky body/design like a black brick. (I don't know, why they built such a huge AVR, it looks like that there is a truck's engine inside it's cover.
