Onkyo HTS590 5.1 Channel Component Home Theater Audio System Review

Onkyo HTS590 5.1 Channel  Component Home Theater Audio System

(More customer reviews)
I purchased this system based on reviews I read at a major retailer's website and here at Amazon. I wanted a home theater system without a DVD player which would offer flexibility. This system certainly offers performance and flexibility for the price. Many features and easy setup.
There are some easy and economical things we did to improve the sound. First, because this system allows you to upgrade the speaker wire, we bought 16 gauge speaker wire from a major discount chain for the center, front and rear channel speakers. We got 14 gauge speaker wire for the subwoofer (thicker wire passes more current to the sub and has improved the performance of the 8-inch woofer). We spent $14 for a coaxial cable at another discount store which carries the digital signal from the DVD player to the Onkyo receiver--this improved EVERYTHING--movies and music. We found speaker stands at a major discount chain for $78--speakers sound much better when they have a strong/rigid support. This may sound like stuff an audiophile would do to a $5000 audio system, but it all is cheap, easy and effective. Sound improved by about 45%.
We were surprised at the tuner in the Onkyo receiver--we're using a small Terk powered FM antenna and getting very good FM stereo reception in our hilly river community. All in all, for the small cost of this system, we're enjoying home theater greatly. We might spend a little to get a new sub at some time, but for now we're really happy.

Denon AVR-2807 - AV receiver - 7.1 channel Review

Denon AVR-2807 - AV receiver - 7.1 channel

(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.

Onkyo TX-NR808 7.2-Channel Network Home Theater Receiver (Black) Review

I bought the ONKYO TX-NR808 to replace my aging 10 year old Lexicon DC-2 pre-amp and Carver Professional amps. The Onkyo powering Miller and Kreisel THX 750 5.1 speaker system.
I figured that after 10 years I could use a audio update even though the Lexicon is still a amazing piece of equipment but I didn't want to spend $6500 this time around.
I wanted a receiver that had all of the newer DTS and Dolby surround formats and could power the 4 ohm M&K speakers (8 vs 4 ohm setting in the setup menus).
It sounds great I love the video switching and the great on screen display of settings.
I have a Netgear 9150 Digital entertainer Elite hooked to it with only one HDMI cable. Being able to use the HDMI really cleans up the cabling since it can also send the audio over the same cable. Same thing goes for my HD cable box, HDMI no seperate audio cable needed.
I haven't had any problems with the Ethernet not connecting, even though I did let it update via the internet. The streaming off connected networked computer is nice also, without any problems. Pandora works flawlessly.
For the price and features it cannot be beat.
Also Amazon has it for the lowest price.
UPDATE: 07-02-11
Still no problems. I now have a HTPC hooked up running WMC and Boxee.
Awesome product for the money.

Denon AVR1610 5.1-Channel Home Theater Receiver with 1080p HDMI Connectivity Review

Based on a sub-$400 budget, I focused on this and the Yamaha 465. In researching it, a toss-up really emerged and the decision was made in talking to a very knowledgeable guy at Crutchfield. Having set it up last night and having played with it the better part of today, I am very content with my purchase. I fired up some Blu Ray's with both PCM and DTS-MA/ True HD and was very pleased with the upgrade over standard DD/DTS. The soundstage was just bigger. The opening scene from my kids favorite movie, Cars, was no longer weak. The opening race scene was clear and appropriately loud. The bump on my stars comes from the fact that the manual is awful. I gave up on it early on and went with the trial and error approach with the on-screen menu, which is more than adequate, but you need to have a basic tech sense in order to take that route. On another set-up note, the microphone setup is well done and made a big difference in the sound generated from my SS speakers, before versus after.

Denon AVR-788 Dolby Digital Surround Receiver Review

Denon AVR-788 Dolby Digital Surround Receiver
Average Reviews:

(More customer reviews)
I'd give it 4.5 stars if I could.
I've had this for about four weeks and only now I am beginning to finish the setup. It sounds very good, for both music and movies. Here are the pluses:
1. It has a audio calibration system that equalises the response to match your listening environment. This one has a 6-position Audyssey MultEQ system (the capability to measure more than one position is important) It seems to do a fine job, although it said my center speaker was inverted in phase when it was in fact correctly wired. It computed the speaker distances precisely and The EQ result looks (they show you graphs) and sounds correct. The setup takes a good 20-25 minutes and you are supposed to do it each time you move furniture. Thats a bit of a drag.
2. It has audio over HDMI support (from the PS3 for e.g.) and supports deep color. It cannot do DTS-HD or Dolby TrueHD, but it can take a 7.1 uncompressed PCM input, which is all you need (i think) because the blu-ray spec requires PCM while DTS-HD and TrueHD are optional. I am not using any of these features yet (so this point is from theory not experiment), but its good to have these for future blu-ray support.
3. It does not get very hot at my listening levels (-12 to -24 db). So I was able to cram it into my existing cabinet (albeit with a little carpentry, since it is over a foot deep)
4. Standby power consumption is under 2 watts. While playing music it consumes about 60 watts at my listening levels.
Like I said, it works well for me and I plan to keep it. But its not perfect:
The Downsides:
1. The remote is terrible, and the user interface is not so good. I liked the remote in pictures - it has big buttons and less clutter than other receiver remotes, but this one is unique. It has buttons on the back (with a cover), That would be alright if you only put those buttons there that you dont need often. However I find that some everyday buttons are in the back - for e.g. the button that changes Sound Modes (DTS/Dolby/ROck/Jazz etc. is in the back) Not well thought out. The manual way to save each FM station requires you to press a button on the back and then two buttons on the front to save one preset. Go figure!
I suspect that all high/mid end receivers have so many features that it will be tough to find one with a good interface, unless you get a all-in-one system like a Bose Lifestyle or 3-2-1.
2. The manual is not fun reading - and some things are not explained. I had to call Denon once to figure out something. (it took two calls and a 5 minute hold the second time, and then I got to a somewhat bored sounding technician. But he seemed knowledgeable.)
3. When I connected the subwoofer line level output to my Bose 701s LFE input (powered subwoofer) I got an audible hum (probably at 60 Hz). I had to buy a ground loop isolator from Radioshack ($12) that removed it.
Overall, a good receiver. In an ideal world, you would try out five brands and keep the one that sounds best to you. The only store where I could compare two brands in A/B fashion was Tweeter, where they had Pioneers and Yamahas set up. I liked the Pioneer Elites better but I think it was because the Yamaha's were setup sub-optimally. Circuit City let me hear a Denon but without the EQ. All in all, I feel that the speakers make a bigger difference than the receiver. I hope some of this helps you in case you are agonizing over the choices.

Yamaha RX-V863BL 735 Watt 7.1-Channel Home Theater Receiver Review

I've had this receiver & its ipod dock for about 45 days. Picked this one over the 663 for its video upscaling. I use it mainly for watching dvds and ipod videos, streaming netflix, and listening to ipod and HD radio music.
Pros: Quality of sound and video output met my high expectations. (I'm biased toward Yamaha already FWIW). Surround fields are versatile & distinct. The enhancer modes are fantastic for low volume listening. Headphone listening is stellar. Config menus are straightforward. YPAO was easy to set up, though I wound up tweaking rear speaker adjustments up a bit as personal preference. The remote runs all our gear. I dusted off old concert and movie DVDs and this receiver makes them seem new again.
Cons: No macro mode on the remote to power everything on & off with one button. HD radio control is not intuitive. So far I haven't figured out if I can navigate a docked ipod's menus with my TV osd which would be nice.
Bottom line: I saved up and looked at a LOT of receivers before choosing this one, and I'm not disappointed at all. The RX-V863 is everything advertised and lives up to Yammy's top shelf reputation.
