(More customer reviews)Denon 4308CI Receiver

Strengths: Great quality picture and sound, excellent build quality, nice display, GUI interface, easy to assign/rename imputs, HD radio, 4 HDMI, 140 Watt multizone output, good value for price point.
Weaknesses: Complicated user manual, Useless remote, Faroudja vs. Silicon Optix processor
Price paid: $1,780 (2/08)from a reputable retail store. (Please do not ask which one as I was given an insider price)
Summary: After considerable research I purchased the Denon 4308CI to upgrade a prexisting Sony STRDA555ES receiver. My main desire in upgrading was to obtain HDMI connection capability and take advantage updated sound processing and 1080P upscaling. I ruled out various other comparable recievers for a variety of reasons, including heat generation as my components are enclosed in a audio rack partially recessed into a closed media room.
As a longtime Sony fan and owner of three ES AV recievers, it came down to a choice between the STRDA 5300ES and the Denon 4308CI.
I opted for the Denon over the Sony for a few reasons. The display on the Denon is much larger. It might sound silly but I like to see the information displayed on the receiver from where I'm listing to music. The Sony display was rather small. I also liked the fact that the Denon has internet streaming capability and HD Radio reception. The Sony has more HDMI hookups and a longer warranty (5 years vs. 2 for the Denon) but the Denon has increased power handling and full 1080P upscaling. Pricewise the Denon was a few hundred dollars more then the Sony but I felt that it had a more "modern" feature set.
So far after 4 months of use I have been very pleased with the Denon. Sound is fantastic and the GUI was intuitive. I disagree with some of the other reviews that I have read regarding the ease of setup. It took a little longer then I anticipated to set up but as I previously noted the GUI was fairly intuitive. I really like the fact that you can rename the inputs so when you select them from the function selection dial it will display whatever name you decide on. I prefer optical connections so I had to reassign some of the optical connections. Rear connections seem pretty sturdy. The unit gets warm but not hot after a few hours of use. Still havent taken advantage of the 1080P upscaling as of yet. HD radio signal reception is pretty strong and so far no interference despite living in a New York City Apartment building.
Harmony 880 Universal Remote works better then supplied remotes.
Video processing is excellent. I have however occasionally noted video artifacts. This reciver uses a Faroudja DCDi FLI2310 processor which is simply not as highly regarded by professional reviewers as the Silicon Optix Realta HQV processor used by Denon's flagship 3800BDCI Blu-ray player or the Silicon Optix Reon chipset used by receivers such as the Onkyo TX-NR905 and Integra DTR 8.8. However, overall picture quality on standard 1080i and 720p cable source material is excellent.
3808CI vs.4308CI? The 4308CI appeared to have a slightly more "attractive" build quality and appearance. In comparing the two models side by side before purchasing, the 4308CI simply looked better. However, HD radio, increased power handling and WiFi capability were the primary reasons I opted to spend more to purchase the 4308CI.
4308CI and 3800BDCI blu-ray combo. Have had the 4308CI and the 3800BDCI paired for the last three weeks. The Blu-ray picture is simply amazing. Will never purchase another standard DVD again if available in Blu-ray format.
Conclusion: I've been very happy with the 4308CI. It offers great sound and picture features at an attractive price point. However,if you are interested in better video processing you may want to check out the Onkyo TX-NR905 and Integra DTR 8.8 as well.

Denon AVR4810CI 9.3-Channel Multi-Zone Home Theater Receiver with Networking Capability and 1080p HDMI Connectivity Review

Average Reviews:

(More customer reviews)Initially, I went through the struggle of choosing separates (pre-amplifier and amplifiers) versus a receiver (where the pre-amp and amplifier functionality is built-in to one unit). I liked the flexibility of having separate components in case I decide to make changes in the future, but simply did not have the space in my audio area to accommodate multiple pieces, hence my choice to look at receivers. There were many receivers to choose from and I found the Denon to be at my sweet spot for value, function, performance, aesthetics and simplicity.
This beast of a receiver is one step below Denon's flagship AVR-5308ci. The AVR-4810ci delivers 9 amazingly clean channels of amplification without breaking a sweat. The GUI-driven menu takes a little getting used to, but after 4 or 5 uses, the menu becomes second nature. There's a plethora of inputs and outputs, and the capability to handle 3 subwoofers coupled with 9 channels for front, front height and/or width, surround, surround back and center channels allows for enormous flexibility with room for future expansion. There are 6 HDMI inputs (with one in the front panel behind the flip down door). Built-in WiFi allows for integration of other networkable sources in your home with no mess or fuss. Having Napster and Rhapsody online access built-in is extremely convenient and very easy to use. Satellite radio (XM and Sirius) can be handled by this beauty as can HD radio. With the USB input, you can playback photos or audio. Freely assignable amplifiers allows for bi-amping, bi-wiring and multiple zones (up to 4) throughout your home. This receiver can even control your iPod on-screen via the USB digital direct connection.
The initial setup process is quick and simple, thanks the Audyssey MultEQ XT Room Equalizer that allows the receiver to setup all of your speakers' time and frequency response, for up to eight positions which is very handy if you have more than one person frequenting your listening area.
The Advanced AL24 Processing Multi Channel features improved dynamics, so my sources sound phenomenal. The 1080p HDMI output via Anchor Bay's advanced VRS processing (using the ABT-2010 chip) and excellent scaling capability makes all of your sources look simply superb! Even your analog sources can be unconverted and scaled to 1080p!!
As usual, Denon's Dynamic Discrete Surround Circuit (D.D.S.C-HD) provides for amazing sonic detail and extended range, with Burr-Brown 24-bit/192-kHz digital-to-audio converters for all channels, rather than just the front two. Dolby TrueHD and DTS-HD Master Audio decoders ensure amazing reproduction of your favorite Blu-Ray discs. As a bonus, you get dual HDMI outputs if you want to output to other rooms or to handle situations where you might have both a video projector and an HDTV flat panel in your theater.
The "ci" designation means that the receiver supports custom integration features if you choose to do some advanced setup or are having the receiver professionally installed/integrated into your home.
If there's one thing about this unit that I didn't like, it's the EL remote. I found the remote a bit clumsy to use and don't really use it much for controlling the receiver once initial settings are accomplished (as I use my Harmony universal remote instead). I also think the User Manual could use some tweaking to make the instruction flows easier to understand.
I heartily recommend this receiver and have not regretted my purchase for even a second! Good luck with your choices and no matter what, ENJOY!

Marantz SR8002 Surround Receiver Review

Average Reviews:

(More customer reviews)After 9 years, it was time to upgrade my former top-of-the-line Sony ES receiver (STR-DA 777ES) to take advantage of improved audio and high-definition video switching. After reading all the professional reviews, I settled on the Marantz SR8002. Three weeks after an extensive configuration and testing, I must say that I am pleased overall with my choice. However, several surprising configuration limitations keep me from giving it a full-on 5-star review.
Let me preface my review by stating that my home theater / audio configuration is on the higher-end of the scale: 3 KEF Reference speakers for the front 3 channels, Boston Acoustics rear surrounds and subwoofer, Sony ES SACD player (and yes, I have an SACD collection!), Bang & Olfusen turntable, Sony reference DVD player, AppleTV, Roku music server, JVC SVHS VCR, Mitsubishi HDTV monitor.
My first priority was in upgrading the audio quality, and I must say that in this respect, the Marantz SR8002 far exceeded my expectations. As a 7.1 channel amplifier, there are 7 x 125watt channels available, native decoding of the latest lossless HD digital audio on BluRay (DTS-HD and Dolby TrueHD), Audyssey microphone and room equilazation, and THX Select 2 certification. For the ultimate audio experience, the Marantz SR8002 offers two "Pure Direct" modes - the first one bypasses the equalization and surround circuits, the second mode completely disables all video and display logic for even shorter audio output path. The SR8002 also provides a toroidal power transformer for extra headroom when needed, and in my setup the audio performance is dramatic.
I chose not to expand my current 5.1 speaker configuration to 7.1 channel. In this setup, the SR8002 gives you the option of taking the two unused channels and configuring them for a second amplified room/zone, or bi-amplification of your front speakers. I chose the latter, as my KEF Reference speakers support bi-amplified wiring, providing 250 watts per channel into Left and Right channels. Let me tell you - the pure stereo performance in this configuration will blow your socks off! Friends could not believe the sound in our fairly large family room was from 2-speakers only. And, the multi-channel modes (especially NEO6: Music) are quite outstanding even with a 2-channel source. Quite simply, the audio performance of the SR8002 is "7-star" on a 5-star scale.
My second priority was in upgrading to a receiver capable of decoding the high-resolution audio of BluRay, while providing high definition video switching (via HDMI and component). In this respect the receiver delivers, but with some surprising limitations. On paper, the Marantz SR8002 offers more connectors and options than you would ever need. You have 4 HDMI 1.3 connections + 2 HDMI 1.3 outputs (good!), 4 component HD connections + 2 component HD outputs (good!), 4 TOSlink digital audio (including front), 3 coax digital audio, and a plethora of S-video, composite video, and analog audio inputs.
But in reality, there are serious limitations...
First of all, it is inexcusable for a receiver of this cost to be missing a phonograph input. Yes, for $50 you can buy a phono preamp that gives you good performance and doesn't have the A/C hum of your $25 Radio Shack unit. But, come on.
Secondly, and more discouraging, despite the plethora of connections you only have 8 discrete settings that can be assigned. (The AM/FM tuner is another, nonassignable input, as is the optional XM radio input). This means that even if you could connect to all of the analog + digital inputs available you can only use 8 of them! This is quite a surprising and serious limitation. Even my Sony ES from 1999 had 12 discrete inputs!
The on-screen receiver setup lets you assign specific HDMI, component, and digital audio for your 8 choices. Each input can also be renamed. But you cannot use a single digital input for more than one setting. And you cannot reassign the analog video (S-Video/Composite) or analog audio inputs.
An example of this strange limitation is the analog input of the "AUX2" input also happens to be used as the Left and Right input channels for the 7.1 input. I had to reconfigure my setup to reassign the "AUX2" input to the digital CD input, which I also connected to the 5.1 (SACD) output from my CD player. Because there are only 8 input settings, I had to assign the "AUX1" (front) input to the digital audio and video inputs from my AppleTV. This means that the front AUX1 inputs are completely unusable, since all 8 inputs were assigned from rear input sources.
Another big surprise was the subwoofer speaker setting. By default, it is set to "mix"...all bass output is diverted to the subwoofer at an assignable crossover frequency. This works well for (and is recommended for) THX and multi-channel video sources. But strangely in "mix" setting, the SR8002 does NOT output the bass to the subwoofer for two-channel analog inputs AND it does not output the low frequencies to the front speakers. I spent about 3 hours trying to figure out why my new (required) phonograph preamp sounded so terrible before I discovered this problem. Setting the subwoofer to "BOTH" properly sends full-range audio to the front speakers. AND, it enables the subwoofer for the simulated modes such as NEO6. Not only does this not make sense, it is not documented anywhere in the manual.
There are other annoyances:
- FM / AM radio reception is below average. I was looking forward to trying the "HD radio" capability, but the tuner reception is so bad that it can never get a strong enough signal to use any of the HD radio broadcasts in my area. Compared with my 1999 Sony ES receiver using the same antenna configuration I can only tune half of the stations. My CLOCK RADIO gets much better radio reception than this $2000 receiver!
- the front of the receiver has two large controls for Source and Volume - each one has a bright blue LED indicator that does NOT move with the control. So, while you might think that the volume indicator would indicate the volume level it doesn't. The bright blue indicators are always at 12-o clock position. And the front input control does not have a positive feedback to let you know you have switched inputs.
- the remote control button/display backlight is ONLY activated when you press one of the two buttons on the bottom of the remote
- the remote does not offer discrete settings for all surround modes or settings (although thankfully there are discrete power on/off codes)
- the onscreen display is very primitive (think 1982 Apple ][+ 40x24 characters)
In summary, despite the outstanding audio performance of the Marantz SR8002 (once you figure out the subwoofer and other settings!), I cannot give this a full 5-star rating because of the serious limitations and limited inputs.

Onkyo TX-NR5008 9.2-Channel Network Home Theater Receiver Review

Average Reviews:

(More customer reviews)This is the 3rd Onkyo receiver I have purchased. The other 2 didn't die, they just became outdated. I was originally looking for a couple models below this level, but the Amazon virtually half-price made this lower priced than than those, and an absolute bargain. My only negative is that using Zone 2 or Zone 3 doesn't allow you to use the full 9.2 channels, but being able to pump out internet or computer tunes to the pool for the kids while still being able to watch Bluray movies in 7.2 THX definitely outweighs the negative. The receiver was very easy to set up and it's filled with the latest technology. If you plan to use the internet and network connectivity I highly recommend purchasing the Netgear XAVB5004 Internet Adapter. It streams at up to 500Mps, works off of an electical outlet, and allows you to connect up to 4 devices to it. I never experience any speed degradation with this combination.

Onkyo\'s new flagship network receiver answers all your home entertainment questions—even some you hadn\'t yet thought to ask. The quality starts at the very foundations: a massive toroidal transformer, 22,000 μF capacitors, gold-plated terminals, and separate transformers for audio and video processing. Speaking of video, HQV Reon-VX offers the ultimate in 1080p upscaling via HDMI, while ISF calibration gets the best out of every video source. On the audio side, 9.2 speaker channels let you take advantage of lossless Dolby and DTS codecs, as well as expanded surround formats from Audyssey and Dolby. The extra channels also allow you to enjoy a multichannel source in your main room and powered stereo in two other zones. Connections abound, with eight HDMI 1.4a inputs, two USB inputs, and an Ethernet port for streaming audio from your PC or internet radio. To simplify set-up and adjustments, Onkyo provides a new overlaid on-screen display and Audyssey room correction. It all adds up to one smart and muscular heavyweight contender.
