Denon AVR-2807 - AV receiver - 7.1 channel Review

My old, stereo-only system consisted of several high-quality source components, separate tuner/preamp/amplifier, and a pair of very sweet (but rather low-efficiency) classic B&W speakers. When the preamp and amp both died after many years of service, I replaced them with the 2807, and added Polk center and surrounds for a 5.1 configuration. The 2807 makes my faithful B&W front speakers sing every bit as sweetly as my old audiophile separates did, with plenty of power to spare. Today my kids were watching Titanic with the master volume set just a wee bit high, and from two rooms away I thought the iceberg was colliding with the HOUSE. (The volume knob covers a rather impressive -80db to +18db range in 0.5dB increments). You even get TWO sets of amplified front speaker outputs, so you can bi-amp or bi-wire your main speakers if you want! And the 2807's quality is not only in the amplifier stage, but also in the DACs. CDs played through a digital input and handled by the 2807's processors are very smooth and detailed.
(If I may insert one gripe re the amplifier: the speaker binding posts are not at ALL flexible. Using spade lugs or pin connectors is pretty much out of the question. Getting the posts to even cleanly accept heavy-gauge bare wire is difficult. Banana plugs work of course, but the posts aren't spaced correctly for standard DUAL-banana plugs. Arrrgghh!)
Surround decoding and ambience processing is also generally excellent. For instance, using Dolby Pro Logic II with a stereo source like a CD generates a pretty nicely stable center image and subtle, unobtrusive surround enhancement; only occasionally will you hear things "breathe" or wander awkwardly into and out of the surround channel. It makes nearly all of my music CDs, and many TV shows, more enjoyable without calling undue attention to itself. Switching to Pure Direct mode (which is actually wonderfully clean, and is for highest-quality stereo-only handling of analog and two-channel sources) almost always sounds flat and less satisfying by comparison. Seven-channel stereo mode is also good for TV shows and CDs, giving room-filling sound with the surrounds driven nearly equally with the fronts. (There are a number of other soundfields, like Stadium, but I found most of them too gimmicky or show-offy to actually use. Stadium, for example, nicely isolates the play-by-play announcer's voice from a sportscast, and then gives it a HUGE echo that sounds like Lou Gehrig giving his farewell speech in Yankee Stadium. Just putting the announcer cleanly in the center speaker for the commentary, and boosting the ambience of the crowd in the surrounds to make you feel like you are at the game would have been a lot more usable and listenable.) DVDs I just play in straight Dolby Digital or DTS mode, both of which are handled superbly.
In addition to great sound, the other major strength of the 2807 is: inputs, inputs, and more inputs. DVD *and* Videodisc. TV *and* Satellite. Two VCR (or DVR) A/V record loops. A front panel input for your camcorder or game. Plus the usual audio in/outs: Phono, CD, Tape (and of course the internal tuner). All video sources have S-video jacks. You also get up to three component video and two HDMI ins, with upconversion, and plenty of digital audio in/outs, ALL assignable as needed. Plus, any of the inputs can be renamed on the display if needed! Don't have a laserdisc player? Use the "VDP" input for something else, and change its name accordingly. I connected my digital cable TV converter to the "DBS" input, and renamed the input "CABLE". Very slick.
The front panel of the 2807 is beautifully elegant and simple. Just power/standby, input select and volume knobs, and not much else, with all the other minutia tucked behind a (nice solid metal) flip-down panel. Sadly, the same can't be said of the learning, multi-brand remote. Some things on the remote are nicely done; the little button that chooses which component it will control (and nicely lights up the selection so you can see it) is placed perfectly where your thumb will easily find it. Same for the master volume adjustment. Nice ergonomics there. Basic functions aren't too hard to use, but the remote has enough buttons for an entire shirt factory, and after a few months, I am still trying to fathom the logic of why some things are grouped as they are, how to make it control my laserdisc player (which it theoretically should) etc. etc. And some things that SHOULD be on the remote, namely, dimming the front panel display, aren't. Plus, it doesn't have very good range. The remote that came with my cable box will easily work the 2807's volume etc. from a seat catty-corner across the room; the 2807's own remote needs to be closer and more on-angle. Most of the complaints you will hear in reviews about ease of use of the 2807 are really the fault of the remote. If after buying the 2807 you have enough left in your piggy bank for a really good programmable universal remote, it would be well worthwhile.
And while you're getting a better remote, pick up a good third-party FM antenna. I found the sensitivity of the 2807's internal FM tuner to be less than stellar, one of its few really weak points. Even strong local stations in my area don't come in all that cleanly using the (typical) cheap wire dipole antenna that is supplied.
Setup and adjustment of the 2807 is a bit tricky, but (for this computer professional) was not overly difficult. But, I did have to consult the manual frequently. For instance, I could easily find and navigate to the initial auto-setup command with the menu/right arrow/enter keys. But after getting there, it resisted all requests to actually start. Consulting the manual revealed that to actually make the auto-setup procedure GO, you have to press the LEFT arrow key at that final stage. (??!) The auto setup procedure, with supplied microphone, worked very well. It correctly identified the sizes and positions of my speakers, gave an error message when one of my surrounds had a loose wire, let me correct the issue and continue, and duly compensated for the fact that my new Polk center/surrounds are several dB more sensitive than my old B&W main speakers. Even so, I found the center speaker still WAY too prominent. Starting from the auto-setup's values, I boosted the left and right fronts slightly, and reduced the center speaker even more. Result was dialogue etc. nicely anchored in the center speaker, but it no longer sticking out like a sore thumb.
If you compare the Amazon pages for the Denon 3806 and 2807, noting the percentages of which item is bought after viewing both, you can easily see that with the 2807 Denon has hit a really sweet value point, giving you a lot of bang for the buck, with plenty of power and features but without useless frills. The differences between the 2807 and 3806 (an extra 10 watts per channel, the Denon Link multi-channel digital input for Denon's high-end DVD players, three-room/three source, touchscreen remote) are not worth several hundred more dollars for 99% of ordinary consumers. I had been considering the 3806, but when the 2807 came out, my choice was immediately clear.
Overall, the 2807 is a jewel. A beautiful sounding, solidly-built, top-quality component. Everyone in my family is thrilled with it. Its minor drawbacks are just that, minor. Highly recommended.
PS: I will repeat the comments of others about making sure to purchase the unit from an authorized merchant (I bought mine from Crutchfield) in order to have a valid warranty from Denon.

Yamaha RX-V2700 - AV network receiver - 7.1 channel Review

Yamaha RX-V2700 - AV network receiver - 7.1 channel

The RX-V2700 has more features than any receiver I know of in any category. The main features that distinguish it are:
* Play MP3s (off PC running the proper software)/Internet Radio
* High Power (140x7 - One channel driven into 8ohm from 20hz-20khz)
* Handles 7.1 multi-channel PCM over HDMI, helpful for Blu-ray and HDMI
* YPAO (Automatically adjusts levels, and bass management features; I believe it also has some basic equalization features)
* Three HDMI inputs (not a common feature of AVRs)
* Can pass 1080P
Cons:
* Remote control longer than usual; controlling network features a pain
* Clunky GUI for network capaibilities
I connected a number of component video sources and audio sources and ran a single HDMI cable to my display. I have no video issues with this setup. I used YPAO to do the initial setup. When that was done I set all speakers to small and the LFE/Bass crossover to 80hz. There's no good reason to let your speakers handle bass if your subwoofer can do it. 80hz is what THX has reccommended. Everything worked fine. The diagrams in the manual of the back panel were hard for me to read. This made it harder for me to try to wire it up with less than two feet between it, and the back wall. There are some photos online of the back panel that might be easier to use.Sound quality is good. If you already had a good receiver, don't expect amazing improvements. Amps tend to sound very much alike. Processing modes are typical. Select straight mode, and it should do the right thing most of the time. I prefer 7-channel stereo for normal music listening, though.
As for video, because I have a plasma, and I feel it does a good job deinterlacing (480i -> 480p) and scaling (to it's native 1024x780,) I only use HDMI conversion. I did play around with the 2700's deinterlacer and scaler options. I saw no improvement. I also see no degradation, which is what I expect. I use the 2700 to convert component to HDMI for a DVD player/Tivo box and my XBox 360.
The network features work ok. I see usual problems with disconnects, etc. To stream MP3's from your computer to the RX, you will need Microsoft Media Connect, or Windows Media Player 11 (which comes with Media Connect.) You don't need to run Win Media, Media Connect will run as a background process, which is nice. Setting it up was easy enough, but I have spent my life working with computers. You will need to go into Win Media Player or Media Connect and add the 2700 so you can share music to it. The ability to play internet radio is one I quite like. You can't add stations, and are limited to MP3 (I think.) The 2700 uses the vTuner database, which is extensive, and you can suggest stations to it. The GUI for the network capaibilities is painful. It's slow for one thing. It will stop displaying with no keypress in 5 seconds or so. However long it is, it's not always long enough forcing you to hit the display button on the remote again. Very dissapointing for a product with a suggested retail of $1700.
As mentioned above sound quality is good. It's powerful enough that I can turn it up as loud as I want without audible distress, and I can't say that about other receivers I have owned. Like most receivers, it's only rated with one channel driven, but don't let that concern you. If it's not loud enough for you, you either have a big room, inefficient speakers or a need to damage your hearing. As for it's sound quality being better than other receivers, I can't say that it is. Most receivers sound pretty close (in tests, even trained listeners have trouble picking out one amp vs. another.)
A brief note about Blu-ray and HD DVD. This receiver will handle 7.1 multi-channel PCM at 96khz/24bits. That allows you to take advantage of the lossless audio formats available on the new high def media formats, such as TrueHD. You will need to set your player to output multi-channel PCM over HDMI. Some people have reported diminished LFE (low frequency channel) when PCM was used rather than bitstream. I don't have room for a full discussion of this alleged issue. It is unconfirmed by any formal review, and some people have reported that LFE over HDMI/PCM works fine. This is only a potential issue if you want to hear the best quality from uncompressed audio on Blu-ray or HD DVD. You always have the option to let the player convert to DTS or Dolby Digital and send that via bitstream over HDMI (or S/PDIF.)
As for video quality, all I asked of it that was it converted component to HDMI, which it does with no obvious degradation.
Why would you spend over $1000 on a receiver? Probably for the feature set, and high power. Yamaha also has a reputation for quality. It's my fifth Yamaha receiver, so I am obviously a fan.
