Denon AVR-2807 - AV receiver - 7.1 channel Review

Denon AVR-2807 - AV receiver - 7.1 channel
Average Reviews:

(More customer reviews)
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.

Denon AVR-2309CI 7.1-Channel Home Theater Receiver Review

Denon AVR-2309CI 7.1-Channel Home Theater Receiver
Average Reviews:

(More customer reviews)
I bought this receiver to replace an aging Sony STI-910 receiver when I upgraded the home theater system with a Sony PS3 that we use for blu ray movies and games. The first thing you'll appreciate is the automated speaker setup and synchronization system. It makes life pretty easy and eliminates the need to manually calibrate the sound output for your room.
I have a fairly big room and was surprised how accurate it got my speakers tuned. You'll need a good 2 hours to get the receiver setup, synchronized, and mapped to your inputs. One thing that some may find hard to do is the setup of each input. It requires you to map each audio, video, and source with each of the primary functions such as DVD, TV/CBL box, etc. But once you do the first one, it becomes much easier.
The remote control is a bit funky though. Denon decided to save space and created the remote with buttons on both sides. The botton side is primarily used to setup the receiver and select the various equalization modes. The front side is used to control each of the devices. This takes some getting used to and is a bit of a hassle for the price you're paying.
But remote issues aside, the sound is great. I cross shopped the Harmon Kardon 354 series, Pioneer Elite, and new Marantz around the same price range. If you have a PS3, you'd better check out the blogs first. The HK has a lot of issues with the PS3 and even after the latest firmware update, there are still some remaining issues. This kept me away from the HK even though that was my original choice.
The Marantz didn't have as many features as the Denon, even though it was just released. I think the sound of the HK and Marantz is slightly warmer than the Denon, but you'll only really notice this slight difference if you're listening to a lot of classical, jazz or vocal pieces.
For home theater, it really drew out a lot of nuanses that my Sony was simply not reproducing. Even my wife and kids noticed the difference with the first blu ray we popped in. The detail was much more pronounced and the auto speaker calibration really balanced out how my speakers were reproducing the volume and sound accuracy for the room.
For music, the receiver had quite a few equalization modes, but what impressed me was how much better the sound stage was in the direct bypass mode compared to my Sony. It was much clearer and had a deeper sound stage with better separation. It's not quite audiophile specs, but it's much better than many of the other low to mid end consumer components I've listened to.
The HDMI switching worked well with the PS3, Denon upscaling DVD player, and TV/CBL box I had hooked up to it. The Denon 2309ci did a good job of upscaling sources from my normal DVD and component inputs too.
I'd recommend this unit to others as the features, compatibility, sound and picture quality are very good for the price. I would have rated it a full 5 out of 5 if the remote was a more user friendly.
Hope this helped.

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

Yamaha RX-V2700 - AV network receiver - 7.1 channel
Average Reviews:

(More customer reviews)
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.

Marantz ZR6001SP Receiver/client Package Review

Marantz ZR6001SP Receiver/client Package
Average Reviews:

I highly recommend this receiver.
"Digital Audio via Electrical Distribution"(DAvED) is so convenient for the bathroom, kitchen, garage, etc. Great technology! Whatever audio you have going into you Marantz ZR6001sp (server) the boom box(client)plays it without effecting what you already have playing out the main receiver (server)... one catch, The Client must be on same electrical phase as the server.
No HDMI Switching, but oh well... It has upconvert for component and enough A/V Surround Sound Theater options that any more is overkill, for any receiver.
The amp is strong and it adds so much to my theater. Movies are a lot more effective.

Harman Kardon AVR-254 7x50W 7.1-Channel Home Theater Receiver with HDMI 1.3a Repeater Review

I spent several months researching my new receiver for my home theater. I spent countless hours hanging out on the avsforum, read everything I could about receivers. I was looking for a receiver that would have the following features:
- at least 2 HDMI inputs
- great sound quality for music as well as movies
- HD audio codecs (Dolby TrueHD and DTS-HD MA) support
- would cost $650 MSRP or less
The choice is clear:
- Onkyo 606 or 705
- Yamaha 663
- Sony 820 or 920
- HK 254
- Pioneer 1018
- Denon 1909 or 988
I didn't even try the Onkyos, because I was afraid of the overheating problems and the humming noise reported on many units. Plus, they are downright ugly. The Yamaha had only 2 HDMI, and did not pass BTB/WTW, the Sonys are notorious for having the worst sound quality (unless you tap into the really high end models) across the board, so I didn't consider those either.
I was then left with the HK, Pioneer and Denon receivers.
I first bought the HK 254. All the users on avsforum swore by the HK sound. Well, they were right. The sound is nothing short of outstanding. The GUI is light-years ahead of the competition too. And finally, it is by far the slickest looking receiver of all.
Now, on the negative. HK is notorious for releasing products that haven't been thoroughly tested, and that don't work properly until the firmware update is released, and even at that point, it doesn't always work right. Well, they got that right too...
1 - the fan noise on 2 different units was unbearably loud, and not only was it loud, it wasn't a constant noise: it was pulsating. Crappy quality control from HK, can't afford more than $2 on a decent fan!
2 - if you connect your PS3 to the HK receiver using HDMI audio out + Linear PCM (the only way to take advantage of the HD audio codecs), here's what happens: you get sound drop outs that last for several minutes in many bluray movies (There Will Be Blood is a good example). Also, in GTA IV, you cannot hear the dialogs from the person you talk to on your cell phone. When I say "you cannot hear the dialogs", I mean: there is NO sound at all, it's not that the volume is low.
3 - the surround sound never "locks" on the one you want, it always reverts to Logic 7 eventually, and even if you can sometimes get it back by cycling through the surround sounds, it doesn't always work and it is a major hassle.
4 - it can't pass HDMI video with video processing turned OFF (it's always on!), and it won't pass BTB/WTW either.
I don't want to go into the details of all these bugs, but they completely kill all the enjoyment you could get from the unit. I exchanged my first unit, thinking I got a lemon, but the 2nd unit showed exactly the same problems, all of them. I finally returned the unit, disgusted with HK's quality control.
I then tried the Pioneer 1018, the Denon 1909 and the Denon 988. All 3 of them performed flawlessly, without a single hickup.
The Pioneer worked great but sounded a little weak, lacked punch and attack compared to the HK. It also had a very annoying bright blue LED that you can't turn off, and the worst remote I've ever seen.
The Denon 1909 and 988 were very similar, the 988 having a very slight edge in terms of SQ for music, but lacked the extra HDMI input and didn't have the Audyssey Dynamic EQ and Volume features. The 1909 was the only receiver I tried that could maintain the surround field perfect at any time and any given volume.
I ended up keeping the 1909, because of its great sound quality and of its superb handling of surround field, thanks to the Audyssey Dynamic EQ and Volume. Oh, and did I mention that it just works? ;)
After my disastrous experience with the HK, I wouldn't touch that receiver with a 10ft pole. If you consider this unit, wait until HK comes up with a firmware update, and make sure that it actually fixed all the problems. For more info about these problems, visit the avsforum dot com forum, and search for "Official Harman/Kardon AVR x54: Problems and Solutions Thread".

After having an unfortunate incident with a lightning strike at my home, my Denon AVR-1908 suffered irreparable damage. Within a few weeks my insurance company sent the check to replace it and the hunt for a new receiver was on.
Having owned a Denon, I was very familiar with the quality and outstanding sound their receivers can produce - but made the decision to research other brands such as Onkyo, Yamaha, Pioneer and of course the new line of Denon AV receivers. I have a 7.1 surround sound Home Theater so my future purchase had to meet that criteria. After some research I had narrowed my search down to the Denon AVR-1611 and the Onkyo TX-SR508 receivers, then visited a local electronics store to compare the two receivers in functionality and sound. After comparing the two I found that the Denon delivered a more rich, deep sound reproduction with outstanding surround sound imagery as compared to the Onkyo, at least in my opinion.
The Denon AVR-1611 offers some features that I definitely wanted, and some that I may want to utilize should I decide to upgrade my Home Theater. It offers HDMI 1.4a inputs and output for 3D movie features (still on the fence with 3D), if I decide to upgrade to a 3D capable Home Theater this receiver will accommodate this option. The rear I/O panel is extremely clean compared to older AV receivers, due to HDMI. There are 4 HDMI inputs and 1 HDMI output eliminating the need for multiple component inputs, this made for a much quicker and cleaner equipment setup. The various available sound formats, i.e., DTS Master, Dolby TrueHD, Dolby Digital Plus encoded with this receiver switch very efficiently with the source material - to date I have not had to adjust this manually. The receiver is very pleasing aesthetically, and fits in well with the rest of my components but does have some heft to it. The Denon AVR-1611 also offers ARC (audio return channel) via the HDMI output to allow for both sending and receiving an audio signal, but please note that your television must also have the ARC feature. The other plus with this receiver is the upconversion of standard definition DVD's due to the HDMI upconversion feature, althought it now sounds cliche - it truly makes my older movies look like new again with near HD resolution. The only criticism I have that prevented my awarding this receiver a perfect 5 stars is the lack of an AC Power Outlet in the back of the receiver. I found this to be a real convenience option for plugging in my JBL PB10 powered subwoofer. I wonder if this has been eliminated due to reducing the overall power draw for electronics in meeting with "GREEN TECHNOLOGY"? Regardless, I found that I missed having the outlet and wish they would incorporate it back into the design.
The owners manual can be intimidating, with its overview of all the features and functions designed in the AVR-1611 - this is where the AUDYSSEY AUTO SETUP feature shines! Denon included a specialized microphone to allow owners the convenience of letting the receiver setup your surround parameters without hours of manual work. Not only did this feature effectively set the surround sound parameters of all 7 speakers and my subwoofer, it also measured the distance from each speaker to the listening area, as well as decibel/gain setting for each individual speaker. It even determined the size of my speakers from small to large! To gauge the accuracy, I took out my tape measure and my Radio Shack sound level meter and began testing, and found the accuracy of Audyssey to be remarkable! For the novice setting up their Home Theater this feature would be invaluable.
To date I can offer no complaints, save for the missing AC power outlet. The surround sound imaging is outstanding, music CD's sound amazing, and the Denon AVR-1611 has real ease of use. It supports all of the most popular sound formats and upconverts my standard definition DVD's beautifully. I would highly recommend this receiver to anyone who is on a budget looking for an AV Receiver that offers a multitude of features and is as close to audiophile reproduction as you can get. It certainly pleases this movie buff.
