Denon DHT-391XP 5.1 Channel Home Theater System with HDMI 1.4a connectivity and 650-Watt Total System Power (Black) Review

I did a lot of research, like most of you will do, and determined that this was the best I could do with my budget. My primary concerns were sound quality and getting enough power for a large room (19' x 20') This does well in those regards, while you sacrifice in other areas. For this price you can't have everything!
Pros:
The components seem quality built. The receiver is heavy and well ventilated. The speakers are heavy and wooden. Everything is just sturdy. It shipped well packed in a heavy box.
The amplifier itself is the same circuitry and power rating you'll find in more expensive Denon receivers, like the 591 and 1611. From what I gather it's THD and power compare well with more expensive models. It certainly does a good job with the included speakers. It will get ridiculous house party loud, no worries.
The HDMI inputs gave no problems. Denon is sometimes noted for handshake problems, but I did not encounter any. I have a Motorola DVR, a Sony BDP-S570 blu-ray and a Samsung PNC50C450 and they all sync up perfectly. I did the latest firmware updates on each device prior to the Denon arriving.
The sound is pretty tweak-able, if you have the patience. More on that later.
The included speaker wires are long.
Cons:
Setting this thing up is tedious. There's no surround auto setup. You need to measure your speaker distances manually. You need to tweak the loudness of each speaker to your liking. They should all be equal. You need to specify the type of each speaker.. etc. The menus are not very intuitive. The included speaker wire is pretty thin 22 gauge. I suppose this is ok, but it seems fragile and I prefer some more durable, less resistive 16 gauge wire for the long runs in my room. You may want to play with the crossover frequencies also. Letting the sub handle everything below 200Hz provided the best results in my case.
At first I thought the sound was muddy. I then did some research on room acoustics and speaker positioning. Most real experts (the ones that work in the field and/or adhere to the scientific method) agree that the room it's acoustics and the position of you and your speakers is the single most important variable in sound quality. I completely agree after re-positioning my speakers three times. The most significant change was moving the sub-woofer out of the corner and into the open. I also got some quality mounts. In conclusion, do some research, put your speakers in the right spots, work with the setup for 3 or 4 days until you get the sound you want and crank it up. After all that, holy cow! Crank it up!

The Denon DHT391XP raises the performance bar for "HTIB" systems. It features the powerful Denon AVR391, a 5.1 channel home theater AV reciever boasting 3D compatible, 1080p capable HDMI 1.4a repeating technology (4 in, 1 out). This allows simple one cable connectivity to any HDMI equiped HD TV. The HDMI connectivity also supports the latest generation surround sound formats available on Blu-ray disc, including Dolby TrueHD and DD+, dts-HD and DTS-HR. The AVR-391's 5 x 110-Watt (6-ohms, 1kHz) amplifier section features discrete circuitry to deliver detail and dynamics to your music and movie selections. Complimenting the AVR-391 is a relatively compact, yet powerful 5.1 speaker package. The front speakers are a 2-way "LCR" design using dual 3-inch woofers flanking a 1-inch tweeter. The surround speakers feature a 3-inch full range driver. Providing depth and impact is an 8-inch, 100-watt powered subwoofer. Combined with the AVR-391, this package delivers 650-watts of total system power. That's a lot of bang for the buck! Enough to please any value orientated movie and music enthusiast.

Denon AVR-3808CI 7.1-Channel Multizone Home Theater Receiver with Networking Review

I have been waiting a while for "the perfect receiver". However, I have come to the conclusion that this is as close to perfect as I am going to find for my needs right now. I am using all 4 HDMI inputs (PS3, Oppo 980H, Directv HR20, and a Sony Vaio computer). The Denon has worked flawlessly with SACD, DVD-A, and lossless audio sources from my BluRay movies.
For sound quality, it is important to get the speakers setup properly. Denon's auto setup with the included mic makes this a very simple setup. I have heard that it helps to take measurements from all over the room, so I setup 5 listening locations. The sound quality is fantastic. I do have an spl meter, but I have not had it out to fine tune the setup just yet. It already sounds fantastic. The Oppo has the ability to send out a DSD multi-channel signal for its SACD and these sound fantastic on the Denon.
I am not really using the video upscaler very much since most of the signals I am inputting are already HD. In other words, the Denon mainly sends out the signals untouched, so it is hard to complain.
The ability to update the firmware over the internet connection is what I believe sets this receiver apart from the competition. For me, this was the deciding factor. With all of the new tech in these receivers, I do not want to have to carry the thing into a service location every time it needs an update.
I should mention that I played some music coming from my computer using the network interface and it worked okay. It did take a few seconds to retrieve license information for Yahoo Music DRM files, but I bet they improve on that in the future.
The downsides are small, but should be mentioned. The remote is okay for setting up the system, but it is going into a drawer with my other remotes now that I have my Harmony 880 universal programmed for all of the general functions that I need. Also, the GUI takes some getting used to. I like the ability to rename the inputs and choose what video inputs go with the audio inputs. However, it was not something that I picked up and setup in a few minutes. It is better than my old Denon AVR-3300, so at least they are going in the right direction!

Denon AVR790 7.1-Channel Multi-Zone Home Theater Receiver with 1080p HDMI Connectivity Review

I bought this to replace my 2 year old Yamaha RXV-2600.
Pros: Excellent surround sound performance thanks to Audessy auto setup, perfect HDMI switching performance, great value
Cons: Muting the sound makes a noticeable "click" sound as the amps are turned off, cryptic manual, lack of THX certification
Despite a couple of minor cons, this is a fantastic receiver. It blows away my older (but much more expensive) Yamaha in terms of sound quality and HDMI switching. The Yamaha YPAO wouldn't automatically calibrate my subwoofer (but Audessy does!) and would give HDMI HDCP errors about every other time I turned on the receiver. The Denon has been working flawlessly for a week.
I would recommend going online and downloading some of the Denon setup guides from avsforum, they are *much* better than the weak excuse of a manual that comes in the box with the receiver.
Highly recommended for an entry level 7.1 receiver!
