A lot of people on this forum use Harmon Kardon and Denon. I believe most useers have said Yamaha recievers matched with Klipch tend to be too bright for their taste. Denon is sort of a flat reserved direct sound, and a lot of people prefer the higher model Harmon Kardons, but to a certian price range, then everyone here will tell you to go separates (Outlaw, Emotiva, Rotel).

I use a Denon 3805 and just recently found an old amp in my mom's house i'm using for my fronts, but the Denon is powering everything else (8.1 system). I play movies and music through the Denon 3910 DVD player and when i was using solely the Denon I thought it was fantastic. For the price, the Denon's have power and an enormous feature set. Their new lineups are coming out soon this year, and if you don't need HDMI 1.3 converting or the new Dolby Plus and DTS whatever formats, stores will be unloading their old stocks and it would be a good time to jump on them. I might be upgrading to a new denon soon and be selling my 3805 if you're interested.

For convenience and price / performance, i don't think Denon's can be beat.

You may want to PM Falcon20x before you decide. He went through two HKs in three months and finally got his money back. He could tell you what model numbers. I used to be a big fan of HK and owned an early model for almost two decades and so I am really disappointed in this poor reliability in some of their newer models.

My vote is for Denon.

I too have heard of recent quality issues dropping with Harmon Kardon, not how they were in the old days.

As far as specs to look, it depends on budget and what you need it for. Everyone's situation is different.

If you're driving a 5.1 system, and you said you have the 82s, i think 50 watts per channels when all driven from that HK is on the low side.

I don't know if you have an HD cable box, upconverting dvd player, and xbox 360 and ps3 and want to run them all together. If so, a reciever with HDMI switching and a lot of inputs to control everything is desired, but it's all price depending.

I can tell you this. The Denon 2307 / 2807 / 3806 goes in price from about ~$700 - $1300 depending on where you look, authorized vs unauthorized dealer, or authorized dealer discount.

My 3805 was ~ 1100 when I got it, brand new from authorized dealer. If you can swing ~1,000 for a reciever, then these Denon's are unbeatable. Any price higher than that, and i believe seperates are the way to go, depending on the power of the amp and the level of processor. What people have siad about the emotiva's are bang for your buck seperates, and then Rotel if you really want to start spending.

The RF 82s aren't the behemoth's of Klipsch's line, like the 83s, but still require good handling from source and amplification. I truly don't believe 50 watts is going to cut it. My 3805 i believe is 130 watts per channel. It's not just necessarily volume you'll get, but clairty throughout the levels you listen them too, and ability to handle the ohm movements.

If you're not that serious about your music / movies, then you dont have to spend much, but you did get Klipsch, and a nice higher end one, so you must be atleast semi-serious. You don't want to buy a ferrari and put low grade oil and fuel in it. You want your baby to perform, and even exceed your expectations. Don't neglect and deny your Klipsch babies that opportunity to shine!

1 more thing, if you're looking to buy at best buy, they can not really negotiate price. A seperate dealer can negotiate below the MSRP for all speakers and recievers / amps / DVD players

Also best buy will pressure you to buy expensive nonsense cables and a warranty plan (Klipsch's warranty is more than adequate, and a good relationship with a dealer can trump a lot of warranties)

also, depending on the size of your room, you may be able to live without the subwoofer for a little bit, and spend that extra money on a better reciever and DVD player, then get the subwoofer later.

You don't even need the Klipsch sub, as most people here attest you can get better bang for your buck with a company like SVS, and get it later on down the line. Subwoofers dont need to match the main speakers as far as product line, they can be mixed and matched with a lot of breathing room.

I don't even have a sub yet, my RF-7s do more than enough in my apartent and shake it as it is.

I used to own a H/K avr-525 and thought it sounded better than the denons I heard. I only recently realized the denon recievers I heard in the past may have either been on the wrong setting or hooked up incorrectly (or maybe I hear sounds differently now). At any rate I now own a denon avr-2805 (one model below the 3805) and it sounds fantastic. Sure the H/K 525 or 630 (AVR models I've heard) provide good power, but I feel the denon avr-2805 process the info better. For the most part (not always) recievers are relevant to thair price class, of course with their own unique sonic footprint. I can't stand some of pioneer's lower model recievers, now the old school vsx-47 and 49tx....unbelievable sound performance from a reciever. I don't now everything and I'm not going to pretend like I do.........but I do know what I perceive as good sound. I know its not in the brands you mentioned, but if your willing to get something used, some of the older pioneer elite models can be had for little. Just an idea.

I agree with schwock5 regarding negotioation. You may want to consider going to a specialty retailer, finding what "Last years Model" reciever they had on demo and negotioating. Thats how I ended up with the 2805...300.00 out the door from an authorized dealer

There was a time a few years ago when authorized dealers were drastically dropping avr-7200 prices online. the avr-525 was a 44 lb beast for a mid priced reciever, and boy did it get hot. I couldn't imagine how heavy the more expensive models are. Do a search on some of the models you have in mind, I'm sure some threads are bound to show up.

Denon would be my last choice...................HK or Yamaha would be my choices........No special order.............

I am with OB on this one, with Denon as my last choice. I went with Yamaha, I compared it with the Denon in the same price range and the Denon did not compare in sound or features. But I do hear good reviews of the HK, but they seem to be a little more money if you just look at WPC.

Of course that's just personal opinion ! [:|] And I can't belive that old rumor is still around about Yamaha's being bright ! Listen for yourself.

Alright here are my .2 cents

 I have a HK 645, it has a nice clean sound but... it was my third receiver in 3 months.
The first one was broke right out of the box, the second receiver locked up after a week  (both HK 445 model directly from HK), the third receiver ( a HK 645 from an online dealer) lost the video side after a week( kind of annoying since all the settings are done through the OSD). I tried every day for a week to see if it would work again, soft and hard resets, etc.... and it did work again but it took a week!! It seems that the receiver had gone into a protection mode and it took that long  for it to lose the memory or cool down.
I have a open rack so cooling was never an issue, and I never had any problems with my other receivers, but I think the HK receivers are way to sensitive to the heat. The  645 was never really hot either but  it was hot enough to mess up the circuit board. I have since moved everything out of the rack and never had an another video problem.
No need to say that HK has major reliability issues, however there service is top notch. They have answered my emails with in 24 hours or less, they were help full and did give me a full refund without any questions, if it was not for the issues I had I would recommand them. Some people here will tell you they have never had any problems with there HK's and it is true, but most of them are using the previous generation of receivers and the problems appear to be only with the new generation 
An another thing, this is not a receiver for newbies , the settings are rather complex and hard to understand if you don't know how to do it, the manual is not very well written either.
The sound quality of the receiver is pretty good and was never questionned just the reliability, it would be hard to find such a clear sound  in receivers for less then $ 699 and I don't think you would be desappointed with it.
If you decide to get one get it from a approved retailer, give it full work out, including the video side ( the video connections has some issues as well), and if you don't like it you can always return it.

I hait to desagree with you  but buying a demo model, even at a low price, is rarely a good deal.
The receivers in demo are being used 12 hours a day, seven days a week, for months. Just do the math  and you will see how many hours they are getting, not even talking about the abuse the receive.

I'm not too fond of the idea of demo units either, who knows what anyone has done in the store to them. My suggestion was just waiting until the new models come out, that way retailers will still have the old (brand new in box) stock in the back and will sell them discounted to make room for inventory of the new stuff.

As far as personal opinion to recievers / speakers / anything, find comparable models in the same price range, and test them all at the store, let your ear decide.

I prefer denon for it's ease of use, reliability, and bang for your buck, atleast on the models i've used. My father's HK seemed very confusing to me, layouts of onkyo's seemed disheveled at best, though I hear their quality is great. Hear for yourself! That's the most important thing.

Does anyone here use Harman Kardon?

Or is Denon or Yamaha better, or maybe another brand.

Thanks for any help

I really like my Onkyo 501 (it's a few years old, so it's only a 6.1). It decodes all the DVD's with any Doly or DTS signal, plays all my CD's with the "Neo:6" Matrix. In stereo mode, it only puts signals into the Corner horns, but maintains the LFE sub-woofer channell for bass down to 23 Hz. The micro detail and thunderous bass is amazing and it cost me less than $200 as a refurb.

My next receiver will be an Onkyo for sure as they now include HDMI connectors and uprezzing to HD. I'm going to wait until late this year or next year as HDTV prices are dropping like a rock.

I can definatly see your point and agree to an extent. But also consider that of all the different brands of recievers, and all the different models in those brands at a specialty retailer the unit may be on "stand-by" more often than actually driving a set of speakers. Also some dealers may work other merchandise in with taking the reciever off their hands even at a good price. Factor those in with a warranty (ensure it is specified) and I would say picking up a reciever in good cosmetic condition with no dents (sign of a possible drop) may be worth a shot. Worst case scenareo its covered under warranty (again as long as its specified) or backed for a certain time by the actual retailer. I've purchased one b-stock unit, one demo unit, and one brand new unit. So far the brand new unit was the first to go belly-up...no amplification to the surround cannels. I'm sure others may have experienced the exact opposite and have had demo or b-stock units go sour, but as long as you cover all your ground and leave yourself an out I don't see the problem. Now to buy a demo unit just on good faith and an audition, thats a whole different story in which I think schwock5 meant with "rarely"

Model: AVR-247

If I were to invest hundreds of dollars into a new AV receiver NOW, it would be the new Onkyo with HD audio support.

TX-SR605 is Onkyo's first AV receiver with HDMI v1.3a processing, HDMI-based system control, and HD lossless audio decoding


For additional photos and high resolution JPEG files, please visit http://www.gspr.com/onkyo/txsr605.html

UPPER SADDLE RIVER, NJ (4/24/07) -- Onkyo has introduced the TX-SR605 A/V receiver, adding processing for the latest lossless multichannel audio formats, comprehensive video upconversion to HDMI, and compatibility with both XM and Sirius satellite radio programming to the impressive features of the TX-SR604 it replaces. The new model also features Onkyo's new HDMI-based system control capability, 7 x 90 watts of power, enhanced compatibility with the company's optional iPod control docks, and a flexible suite of multi-source/multi-zone capabilities.

The TX-SR605s two HDMI v1.3a inputs provide the most advanced interface for transporting both uncompressed high definition (HD) video and uncompressed multi-channel audio in all HD formats including 720p, 1080i and 1080p. It is among the first receivers available to include decoding for Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master multichannel audio formats from Blu-Ray and HD-DVD players.

The TX-SR605 is Onkyo's first A/V receiver to include the company's RIHD (Remote Interactive over HDMI) communication protocol. This feature allows for automatic integration of many system control functions between compatible components via the HDMI connection. Common functions include one-button system on/standby control, volume control punch-through from display remote control to the A/V receiver, and a 'direct change' function to automatically select the correct receiver input and begin playback for RIHD source components.

In addition to its two HDMI inputs, the Onkyo TX-SR605 includes three component video, five S-Video, and five composite video inputs to accommodate other sources. There is upconversion of all composite and S-video inputs to both HDMI and HD-quality component video to eliminate the need for multiple redundant video connections to modern video displays. For displays that are not compatible with 480i video, the receiver also provides Faroudja DCDi de-interlacing circuitry to convert 480i signals to progressive scan. There are a total of five digital audio inputs, as well as five A/V and two audio-only analog inputs. Front panel A/V inputs, including optical digital jack, allow easy connection of A/V or audio devices such as a camcorder or portable mp3 player.

The TX-SR605 includes the Audyssey 2EQ automatic speaker calibration feature that provides remarkable improvements in performance by calibrating the home theater system to its acoustical environment. With this system, the included calibration microphone is used to analyze the system's acoustical output at two unique positions in the listening area. By taking readings in two different positions in the theater room, with the included microphone in the listening position, the receiver sends test signals to each speaker in turn, then uses the input from the microphone to adjust channel level and time delay settings for each speaker.

The Onkyo TX-SR605 makes it easier than ever to bring Satellite radio into the living room, featuring compatibility with both XM and Sirius satellite radio programming. The addition of an optional tuner system for either network enables consumers to subscribe to and receive hundreds of channels of commercial-free music, news, talk, and entertainment programming. The receiver even includes onboard Neural Surround processing for reception of multichannel XM HD surround programming. Finally, there is also a high quality terrestrial radio tuner, and the TX-SR605 features 40 presets for AM, FM, XM, or Sirius stations.

Onkyo has also designed the receiver to take complete advantage of the company's optional Remote Interactive iPod dock/charger units. With the iPod placed in the dock, it becomes a source component for not only audio playback, but also for photography stored in iPod photo units. Basic iPod controls such as play, pause, stop, skip, and random / repeat functions can all be operated via the TX-SR605's preprogrammed learning remote control.

The TX-SR605 amplification modules benefit from Onkyo's exclusive WRAT (Wide Range Amplifier Technology) and Optimum Gain Volume Circuitry, delivering 90 watts per channels into 8 ohm loads. There are sturdy five-way binding posts for all seven full-range channels, and the rear surround channels can also be employed to provide a second set of Front L/R channels for speaker bi-amplification.

The TX-SR605 also features Onkyo's Powered Zone 2 capability, which can be used to power stereo speakers in a second room while listening to 5.1-channel sound in the main zone thanks to a dedicated set of zone 2 L/R speaker terminals. The receiver is capable of processing separate multichannel and stereo sources simultaneously for the main and second zone, or processing a single source for both. There is also a zone 2 pre-out that can be used in conjunction with a dedicated zone amplifier or receiver.

The Onkyo TX-SR605 will ship in May in both black and silver finishes, at a suggested retail price of $599.

Onkyo, which takes its name from the Japanese "On" meaning 'sound' and "Kyo" meaning 'harmony,' has been producing precision audio components for over a half-century. The company's philosophy is to deliver products that are superbly designed and built to a consistently outstanding standard of excellence. Today, Onkyo is at the forefront of the home theater and digital revolutions. For more information about this and other fine Onkyo products, visit www.onkyousa.com or call 800-229-1687.
