High-res audio

Answering the call for more immersive sound

Ever look up wistfully at the ceiling in your home theater and wonder, “Why can't I get sound coming from up there?” Well, your daydreams have come true with the Onkyo TX-NR737 and Dolby Atmos®. With a firmware update, this receiver will be equipped with Dolby's latest surround sound breakthrough. It allows you to project sound from above your seating positions, for a new level of immersion and realism with movie soundtracks. Dolby Atmos is just the beginning of this receiver's features: 4K upscaling with Marvell Qdeo™ video processing, HDMI 2.0 connectivity, wireless music options, and seven channels of slammin' power make this receiver an excellent upgrade to your old receiver or a great starting point for budding home theater lovers.

Dolby Atmos adds a new dimension to sound

Dolby's latest surround sound technology was designed to bring a new level of immersion to your home theater. By employing in-ceiling speakers or special Atmos enabled upward-firing speakers that reflect sound off your ceiling, Dolby Atmos offers a greater sense of space for sound that's more three-dimensional. Already at work in film production studios and many movie theaters, Dolby Atmos represents a huge step in putting more "theater" into your home theater.

The TX-NR737 lets you add two overhead or up-firing speakers (sometimes called "height" or "top" speakers) to a conventional five-channel system — this is referred to as a 5.1.2 Dolby Atmos setup. You can use either one or two subwoofers with this setup.

Wi-Fi and Bluetooth offer lots of music choices

Music is increasingly delivered from sources other than shiny discs. Smartphones, tablets, computers, Internet radio, and subscription services offer a wealth of listening options. You can take advantage of all of them with the TX-NR737. Stream music from smartphones and tablets over Bluetooth, to play audio from any app through your home theater speakers. If you have a digital music library stored on a networked PC or storage drive, Wi-Fi lets you play those tunes over your home network. There's also built-in support for Spotify®, Pandora® Internet radio, SiriusXM, and free Internet radio streams via TuneIn radio. With so many choices, you'll never have trouble finding something to listen to. Plus, Onkyo's Music Optimizer helps restore musical enjoyment to compressed files and Bluetooth streams.

Onkyo's free remote app for Apple and Android

Listen to music from online music services using Onkyo's free remote app for Apple and Android smartphones.

Emphasis on sound

The 'NR737 is about more than just convenience and versatility. Onkyo has always put a premium on sound quality. This receiver features their Wide Range Amplifier Technology, which provides plenty of current to ensure smooth sound even during large swings in dynamics. This reduces distortion while ensuring music and movie soundtracks have plenty of punch. Phase-Matching Bass Enhancement keeps low-frequency tones from muddying the midrange, so you get plenty of deep bass while vocals and dialogue remain clear and detailed. And if you've downloaded high-resolution music from sites like HDtracks, you'll appreciate this receiver's ability to decode high-res files like FLAC, WAV, Apple Lossless, and even DSD.

Add music to a second and third room

If you'd like to add speakers to an adjoining bedroom, kitchen, or porch, you can plan ahead with the TX-NR737. There are powered Zone 2 outputs, so you can connect an additional set of speakers for use in another room. There are also line-level Zone 3 outputs, so you can send audio signals to a separate receiver in a third room — a great use for your old receiver when you upgrade to the 'NR737. While the kids enjoy a movie on cable in the home theater, you can chill out on the porch and listen to music from Spotify® and still have different music playing in another room. There's also a second HDMI output for use in large rooms with both a projector and a TV.

Simple setup and control

The tiny microphone that's included with the TX-NR737 is your key to properly calibrated home theater sound. Plug it into the front of the receiver, and let Onkyo's AccuEQ optimize your system for your room and speaker setup. This ensures you'll get the best possible sound in your room, even if its odd layout forces you to place speakers in less than ideal locations. Before you start exploring this receiver's features, be sure to download the Onkyo remote app to your Apple® or Android™ smartphone. It offers easy control of the receiver's most important functions, as well as giving you instant access to Internet radio and other online music choices.

    Good feature set for the price

    Written By KCB, California on Tuesday, October 06, 2015

    Crutchfield Customer Review (What's this?)

    Caveat: I am not an audiophile, and this is the first receiver I have purchased in over 10 years. So some of the following may reflect my lack of knowledge.

    The receiver generally works as advertised, I am satisfied with the sound it products. I bought this mainly because I wanted a system that could drive the home entertainment system in my living room (e.g., TV surround sound) and have a separate powered speakers for the rest of the house (dining room, kitchen, patio). I connected the Zone 2 powered output to a Niles passive switch box to feed the ceiling speakers in the rest of the house.


    Cons: Initial set up was confusing. I figured it out (with good tech support from Crutchfield), but manual does not make it clear. To get sound in Zone 2, go through steps to select Z2, select input for Z2, then manage volume for Z2 separately from main zone. Easy after I did it, but took a while to figure out how; the manual is less than clear. 2nd issue is audio from STB delivered via HDMI to Onkyo receiver will not play in Zone 2. Can't play music from STB in whole house.

    Just what the Dr ordered!

    Crutchfield Customer Review (What's this?)

    Haven't used all the features yet, but setup was easy and is performing better than expected! Using in our movie theater and music in two other zones. Looking forward to testing the Bluetooth and WIFI settings on other speakers.

    Pros: Easy to setup and use. Clean power pushing atmos home theater.

    Cons: None

    So far so good

    Written By N, Massachusetts on Tuesday, September 29, 2015

    Crutchfield Customer Review (What's this?)

    I set up the receiver with very little problem, paired with a DefTech 5.1 system. The manual included in the box was for a different Onkyo receiver, so the back panel was set up slightly differently. Not really a big deal though as plugging in the various wires was easy. The auto-calibration feature doesn't seem very good; it ended up adjusting my sub way down, to the point where there was no bass, so I had to manually adjust the setting to bring it back up. Paired my computer and phone via bluetooth without a problem, and the sound is great.

    Great features and sound

    Written By Nick, Albany, NY on Tuesday, September 22, 2015

    Crutchfield Customer Review (What's this?)

    This performs well compared with the old Sony's I've always used. I switched to the Onkyo because of the upconversion from Component/Composite to HDMI. Setup was very nice and the included color coding labels will be nice for changes down the road. This system is paired with a Definitive Technology ProCinema 600 set. The performance is very nice for both music and movies. I haven't setup with Atmos yet, but may down the road.

    One review mentioned the long startup time - this is definitely true, but once it's on, it's great. I especially like the CEC functionality which switches inputs etc as necessary. This makes use for my wife and son much easier. I am however surprised at needing to operate at 50 (50% power) to hear things well. Other receivers in the past have operated in the lower, 30% range. I expected, given the power output of this unit, it would operate in a similar range (the speakers have a ~89dB sensitivity).

    All and all, it is a solid buy.

    Easy to use

    HDMI video output failures

    Written By JonW, Texas on Saturday, September 19, 2015

    Don't buy this unit! I have had my unit for two years and the HDMI video output has failed three time. Requiring me to send the unit back several times. I am switching to another brand. Additionally, hard to use with apple products.

    Bang for the buck

    Written By timc, Tennessee on Friday, September 18, 2015

    Crutchfield Customer Review (What's this?)

    So far this has been a very good replacement for my Denon AVR 900x. The wired connectivity can get about anything you have hooked up and the wireless/wired connections to the network work well. It is much easier to use than my Denon as far as direct access on the front of the receiver as well.

    Pros: Loud and clean reproduction. Well shielded even with my left channel less than 3' away. Easy to use with or without the remote. Clear connections on the back.

    Cons: Remote is pretty weak for a higher end receiver. Looks like a plastic kids toy.

    Good sound quality, no WiFi, mult problems

    Written By jms, Washington on Wednesday, September 16, 2015

    Crutchfield Customer Review (What's this?)

    This receiver/amp does a very good job of taking HDMI inputs and putting out very high quality, very clear sound through the attached speakers. Comparing it to my older Sony amp, the sound difference is incredible. Music comes through very clear, same with movie dialogue, etc. I've also used it to stream Pandora via a wired LAN connection, and it too sounds great.

    However, there are some significant shortcomings to this unit.

    Pros: Good HDMI audio, streams via wired LAN

    Cons: No WiFi. Called Crutchfield tech support, we went over all the settings, decided it's a defective unit. Replacement unit also doesn't do wireless. Onkyo tech support kept me stuck in a voice menu loop, no human. Optical digital audio in has a noticeable delay. Remote control is very unintuitive to use for anything other than switching inputs or adjusting volume. PDF user manual has no index or table of contents.

    Excellent Receiver

    I have purchased Onkyo sound equipment for the past 15 years. The unit has excellent sound, and is loaded with many features. The price was excellent as well. I would purchase again!

    Pros: Great Features, Sound and Power!!

    Cons: Remote and interface are a little difficult to navigate. Power Cord is not detectable.

    I have had Onkyo receivers and components since the 70's. Their quality is well above the rest. Connecting this unit was easy but figuring out how everything works takes a little time. The system sounds amazing!

    Excellent Product!!!

    Written By Muzaclover, Illinois on Thursday, September 03, 2015

    Crutchfield Customer Review (What's this?)

    I've been using this Onkyo for about a month now and it is fantastic. I've got it bi-amping some mid-quality speakers and I doubt I've ever heard music with better sound quality. Because it can drive 7.1 channels, I've got 4 speakers plus a woofer going which makes the sound super surreal. I keep the volume really low, between like 25 and 35, and cannot believe how much I hear. This is a really solid reciever. The wifi capabilities mean I don't have run things like pandora through a phone or anything either, which is super nice.

    Pros: Excellent sound quality Solid features regarding input sources

    Cons: Doesn't have a detachable power cable.

    Difficult to program

    Written By HG, Arizona on Thursday, September 03, 2015

    Crutchfield Customer Review (What's this?)

    Very difficult to program. I think it requires a TV and some patience. So if you don't have a TV and you just want to hook it up with your laptop or listen to music, don't expect to go far on programming it.

    Written By RalphD, Massachusetts on Saturday, August 29, 2015

    Crutchfield Customer Review (What's this?)

    We returned this unit after a few days and were disappointed overall with its performance. For about the same money, the Denon S910W is a much better choice (at least for us). 2 deal breakers for us: 1) The Onkyo is really Apple unfriendly vs. Denon. The USB port on the Onkyo doesn't recognize Apple products. This is in the specs, but I guess we didn't look close enough before buying. 2) When using an internet audio source or bluetooth, you cannot select a different video source. So, say you want to listen to Sirius/XM and watch the game.....forget it. That's crazy and the Denon allows complete audio/video selection control. Also, the zone 2 control seems easier to navigate for us....not a big deal, but it's a nicer interface. We're a lot happier with the performance of the Denon.

    Written By TonyG, Florida on Friday, August 21, 2015

    Crutchfield Customer Review (What's this?)

    As usual Onkyo packs all kinds of great features and quality into their tuner/receivers (this is my 3rd unit purchased over the last 20 years), and prices them reasonably, especially when you connect with a sale at Crutchfield! With 7.2 surround, Dolby Atmos, Bluetooth and WiFi they have done it again.

    Pros: 110 watts per channel, 7.2 surround, Dolby Atmos, WiFi, Bluetooth, 7 HDMI inputs, Zone 2 & 3 capability, AccuEQ room calibration, and 2 sub woofer outputs.

    Cons: Once again, trying to set up the unit and decipher the Onkyo manual is a test of patience. And the more they design their components to be totally electronic and automatic the harder it becomes to set up a system properly. But once done - a great sound system for sure.

    Great receiver, terrible app

    Written By Anonymous, Texas on Tuesday, August 18, 2015

    Crutchfield Customer Review (What's this?)

    This receiver has been mostly great. I love having the ability to expand into three different zones for music purposes. The only problem with this is the Onkyo app. It was designed to make the user experience much easier and efficient, but poor development has only led to frustration. The app fails to connect to the receiver (via Wifi) half of the time and takes a long time to connect whenever it does happen to find the receiver. Once it has connected, the layout is very user friendly and easy to navigate. I personally use Spotify to stream music. A little under a month ago, I was able to use the Spotify app and just connect to the receiver through that interface. I guess there was an update to the Onkyo app and now I have to go through that app to play Spotify. The Spotify interface within the Onkyo app is terrible and works less than half of the time. I have since ditched trying to use the Onkyo app and use an Apple Airport Express to stream my music.

    Pros: Great features 3 Zones

    Cons: Terrible App

    New Receiver for wife

    Written By Eric, Kentucky on Saturday, August 15, 2015

    Crutchfield Customer Review (What's this?)

    Replaced a Samsung Blu Ray receiver and speaker set with this because the Samsung was flaking out and switching inputs randomly. I have an Onkyo 709 for the downstairs set up and after calling Samsung and Crutchfield about the problems with that receiver I decided to jump on a real surround receiver. I already knew what I was getting and am well pleased with the product in all areas. The price was less than I paid for my 709 and I expect the same service and reliability out of the 737, which is basically the same as the 709 with updates to output versatility. It sounds so much better than what was in place and the Samsung has been relegated to doing duty as a blu ray and netflix player. Thanks to the Crutchfield team!

    I've been watching the Onkyo receivers along with the Pioneers and Denon. The price was right on this model for me and does everything I ask it. Easier to set up than I expected and works very well with my Samsung TV. I had to use a workaround for the automatic hdmi switching but no big deal. The Onkyo app is very useful and easy to use. Buy with confidence.

    Crutchfield Customer Review (What's this?)

    Read every review, Crutchfield. The receiver cannot be as powerful as advertised. It is finicky about when and how it works, clicking on and off at will. No lighted selectors on unit, the remote is small and not up to par with my 24 yr old Sony. Good luck programing remote. Owners manual, basic, is poorly written and advanced manual has to be viewed on line or downloaded. It is big, needs lots of space. Connected easily to wifi but the menu for preloaded stations is difficult to maneuver. It was a good price and that is why I am giving it a little time. Some of the difficulties may be my, "remember the good old days attitude." Regardless, I work with computers everyday and still found this receiver annoying to setup and operate. When I called for technical support the tech simply did what I did and opened the "advanced" manual online. After ONE HOUR and TWENTY SIX minutes the tech offered to give me a return authorization # even though we did not know the receiver had any problems. He and I just did not know how to operate the receiver. Called back later and another tech figured it out with me. If you call for help ask for someone who has experience with this unit.

    Pros: Price, connected to wifi easily and tech help was patient

    Cons: See above

    Great High End Receiver!

    I had to replace my Marantz as it had an odd POP noise at times. I read online it was common. I feel like buying a Marantz is like buying a BMW; the best looking receiver, just keep your fingers crossed it doesn't break. I'm a previous Onkyo owner (3rd one now) and only had good luck. I should have stuck with it. One thing this has that the Marantz didn't is a viewable volume level. The Marantz only has a tiny circle which you cannot see from your media chairs (or couch). The sound is also far superior here as I'm getting far better imagine for things like a helicopter flying over. I run a full Definitive Technologies 8080 setup and the sound is now perfect!

    Pros: Easy to read volume. Far superior sound. Onkyo quality. Easy setup.

    Cons: None so far.

    Onkyo TX-NR737 utopia!

    Crutchfield Customer Review (What's this?)

    I upgraded from a nonHDMI input Onkyo receiver to the Onkyo TX-NR737. What an improvement! Having my HDMI components run to the receiver and one out to the TV simplified my connections. It also improved the sound quality immensely. My kids think streaming music to the stereo via Bluetooth is the best feature. The only problem I have had is it won't recognize my MacBook Pro when the "PC" input is selected. Overall, I would rate this receiver as "why did I wait so long to upgrade."

    Pros: Bluetooth, HDMI in and out, improved sound quality

    Cons: Won't recognize my Mac laptop

    This receiver does everything we wanted, and more! We are so pleased with our purchase.

    Pros: It has multiple zone options & enough power to create a wonderful sound thru all of our speakers.The on screen set up is easy to follow, and the EQ sound set up is fool proof.

    Cons: None that we have found, so far.

    Crutchfield Customer Review (What's this?)

    Crutchfield tech support was there to help get me connected. Great company. I have purchased several items from them. Would highly recommend Crutchfield.

    Pros: This receive has a lot to offer anyone in the market for a replacement. I have had a Kenwood, Sony, and Pioneer And by far this is the best. Love that its built in with Wi-Fi, Bluetooth, no additional adapters to purchase unlike other brands. Zone 2 allows you to run additional speakers to other rooms inside and outside while someone is watching tv in the main room.

    Cons: Wish it came with more detailed instructions. You must download the advanced manual to understand all that this receiver has to offer. It is a little difficult to set up but Onkyo and Crutchield were great walking me through it.

    Took an afternoon or so to get everything hooked up and set up just right but that was expected. I have it set up for 7.1 now but will switch to Atmos when more/some streaming content is available. Great complement to my new Sony 70" 4k tv. Audio return on the main HDMI cable works great for Netflix downloads to the tv and the receiver automatically senses and switches over to this audio imput. An unexpected surprise since I did not read that on the spec sheet! All I can say is WOW! Everything looks and sounds fabulous. The only thing better than this receiver is the Crutchfield customer service. I have called 2 times now with set-up questions and they have been terrific! I am a very happy and loyal customer!

    Pros: All good!

    Cons: None- other than complaints from my wife for spending too much time in my man cave :)

    Excellent Sound

    Crutchfield Customer Review (What's this?)

    I bought this receiver as a replacement for my 28-year old receiver (yes, you read that correctly). What was completely unexpected was the incredible sound quality of the Onkyo. My old receiver was top-of-the-line when I bought it, and sound quality is the thing for me. I don't have a lot of sophisticated video requirements, though the Onkyo is superb in that respect as well. I had been thinking about replacing the old receiver for quite some time, and when I saw this on sale, I decided it was time. When I hooked up the new receiver, I couldn't believe the difference. If you've been thinking about upgrading your retro gear, I think you'll be very pleased with this receiver.

    Pros: Sound quality

    Cons: The on-screen set-up could be a little more user-friendly and interactive.

    Pros: pretty easy to navigate. easy to hook up components. Love how you can connect it to a home network.

    Cons: The volume banner (display) shows up in two places. It may can be fixed but haven't figured it out yet.

    Crutchfield Customer Review (What's this?)

    I replaced a 7 year old Pioneer Elite receiver with the Onkyo TX-NR737. The Pioneer was almost twice the price when new and was THX,1080P upscaling, etc. The setup on the new Onkyo was SUPER EASY! The surround sound is better, not necessarily louder, just better dispersion. It seems they have figured out that the surround speakers need a lively center channel for dialogue and equal power front and rear. I have the Onkyo connected to my PC via an HDMI and am using the built in wifi to connect to the internet apps on the receiver. Setting up the remote to work with all of my existing remotes was a snap. Setting up the second room audio was easy as well. From unboxing to having everything plugged in and configured took me two hours. The old Pioneer took two days to set everything up. The biggest bonus with the Onkyo and the thing I didn't expect was that the Onkyo receiver gives our 1080P TV a noticeably better picture! Much sharper and well defined images. My wife's response was WOW the picture is WAY better! Overall the Onkyo has impressed me with it's ease of setup, picture and sound quality, and clean looks. The only things I would change are a remote with lighted buttons would be nice and I wish it had a switched A/C outlet in the back.

    Pros: Ease of setup, picture and sound quality, clean quality looks.

    Cons: Remote is difficult to see in low light. Needs a switched A/C outlet for my powered subwoofer.

    Great Feature Set - Wi Fi Didn't Work

    Written By JP, Minnesota on Wednesday, June 03, 2015

    Crutchfield Customer Review (What's this?)

    Have to go right in the middle on this review for now. Just got it. Set it up no problem with the important exception that the wi fi didn't work properly even when it showed 100% signal. The signal came and went as it pleased. I need it VERY stable so I can run the Onkyo remote app which requires wi fi and my house remote control which uses the IP control this amp offers. Everything worked great while in those brief times when wi fi WAS working however. Crutchfield was great when I reported it. They are sending a replacement no charge both ways. Assuming the wi fi works on the new one I'll give the unit very high marks because everything else about it is great.

    Pros: Great feature set. Easy set up. Crutchfield as the vendor.

    Cons: Assuming the wi fi works on the replacement unit I will have no cons to report.

    Written By the Bri, Colorado on Tuesday, June 02, 2015

    After owning Yamaha, and onkyo previous models, I really have to say I love this new onkyo 737. I didn't think that the THX would mean anything but having the THX modes on this receiver is sooo, cool. I glad I upgraded from the 636 . However, saying these things,if you look at the features for 636,737,and 838,there really isn't a noticeable difference other then the THX goodies. I say go for it. You don't like it , return it.

    Pros: A lot of power , thx modes. The sound.

    Cons: Only gripe, it looks like any other onkyo.

    Solid receiver

    Written By kermit88, New York on Tuesday, May 26, 2015

    Crutchfield Customer Review (What's this?)

    I was very happy with my original TX-NR606, but was definitely looking to upgrade the on-screen functionality on my new receiver. I alsow wanted to make sure the device is 'future proof'. The 737 has ATMOS, 4K pass-through and updated HDMI copy protection that should hold me through until the next leep frog technology. I will definitely be upgrading my room to ATMOS, but is currently a 7.1 configuration. The 737 has wifi, but I decided to use regular Ethernet instead. The unit is larger than my 606 and will generate more heat, so I had to move some components and gave it a large space to allow heat to flow away. I was able to view the sources and use the on screen display to walk through the other settings. It took a little playing around to learn the key sequence to enter the setup mode on the remote. I'm happy with the on-screen display, it really takes some of the guess work out of switching systems. The input source is right on the screen, and I like seeing what the volume level without having to squint to the equipment rack. I really like the IntellaView feature. It is a Picture In Picture for your video sources. I can be watching Cable and see what's happening on TIVO and then easily switch to it. Sound quality is very good. The decoding for movies is excellent and the amplifier matches nicely with my Polk speakers. I did need to adjust some of the channel levels, but this was easy. I was able to stream Sirius easily and so far it has worked as expect

    Pros: Future proof features, Picture in picture that works, great sounding amplifier and decoder

    Cons: Surround setting for sporting events is not as good as Yamaha, stadium sound setting is sub par in the Onkyo

    Very fast shipping on this product. Easy online ordering. Very much recommend Crutchfield and the OnkyoTX-NR737. The Onkyo 737 is all it is advertised as. I purchased the unit to do home theater and music and it does both super well. This is the first amplifier i have owned th as t is up to doing music well. It is also very powerful for the wattage output. I will buy Onkyo again and it will come from Crutchfield!

    Pros: Powerful multi mode home theater amp. Powerful music amp. No muddy bass or mids. Easy to set up. Easy to use. Nicely built.

    Cons: No short comings.

    Great Receiver

    Written By Tigrhntr, Massachusetts on Thursday, May 21, 2015

    Crutchfield Customer Review (What's this?)

    This is a great upgrade, considering Crutchfield's sale price and the ability to decode Dolby ATMOS programming. The unit walks you through an easy setup procedure (which, of course you can return to in the future for tweaking). I have a simple 5.1 setup now, but plan on adding ATMOS speakers (WIDE or HEIGHT) soon to take advantage of some newer Blu-Ray ATMOS content. On this model, you will have to perform an upgrade to the latest firmware to get the ATMOS (and other) features. The process is well- written on the Onkyo web site, and took me about 30 min. The unit has plenty of power, however, the volume really doesn't start being audible until about "40" on a scale to 100, from there it ramps up predictably, and we find a good movie needs to be at about 65 - 75 for good surround effect. We are using Infinity Primus towers for L-R,,matched with an Infinity Center speaker, Polk Audio TL-2's for our surround, and anInfinity 12"powered sub. A nice feature is the ARC, or audio return channel on the main HDMI output - this mated with an ARC on our TV HDMI-In allows for streaming services from the TV to transmit their sound to the Onkyo. Another nice feature is the network- ready nature of this receiver, both WIFI and Ethernet are included. Supports DLNA, so a networked drive now serves up our music; or use a Bluetooth connection from your phone or tablet to stream music to the Onkyo. Still learning some functions, but this is one great receiver that fits our sound needs.

    Pros: WIFI, Bluetooth, ATMOS capable, THX Select 2, ARC, HDCP 2.2 on one HDMI port, banana jacks

    Cons: Remote not back-lit, runs a little hot (use a small fan), not small speaker connector friendly (interfere with each other)

    Great so far

    Crutchfield Customer Review (What's this?)

    Purchased receiver to drive a 3.1 SVS system. So can't speak for multi-zone or 7.1 capabilities. Auto-microphone set-up was easy and quick. Microphone cord was just barely long enough for my living room but worked fine. Receiver easy to set up and use. UI is fairly straight-forward and only a little dated looking. Perfectly functional though, I've found. The Spotify integration works very well and the addition of receiver volume control from the app (Samsung Galaxy Note 4) makes it my go to listening app. Plenty of power from the receiver for my needs.

    Pros: App integration, auto-calibration easy to use, plenty of power for medium room and bookshelf speakers

    Cons: Only minor quibbles: Receiver won't win any styling awards. Takes a bit longer to power up than some receivers I've had (10-20 seconds). Display doesn't auto-adjust to room brightness. Initial firmware update takes about 20 minutes.

    The unit has done everything that was advertised. I upgraded from a 12 year old model that had only RCA jacks. When started looking for a new unit I had to have one that incorporated the RCA and HDMI. I had a lot of different equipment which I could record from. The 737 dos not have the direct capabilitythat my old Onkyo had. It was my mistake of thinking that the new unit would do all that the old one did.

    Pros: Has made my old Infinity speakers sound great again. The automatic speaker set up was easy and made the room sound great.

    Cons: Bluetooth isn't working yet, if I fail on the second try I will call the support line. Wish I could record with this unit.

    The price = a lot of bang for the buck, and I have had good look with Onkyo products already. It has all the features needed for 4K television, which I will be purchasing soon. But a large part of my decision is based on the able guidance provided by Sonny in the Sales Department. In multiple conversations, he cheerfully and supportively answered all my questions regarding the purchase. Crutchfield is tops in sales and technical support. Everyone I know hears my reports.

    Crutchfield Customer Review (What's this?)

    I've had this receiver a little over a week now. I love it! I get clear, clean music even up to the point where listening becomes painful. Once again, Onkyo has built a winner. I've been using and upgrading their products for over 30 years now and have never once been disappointed. In fact, I'm still using the old Onkyo PL-25F turntable I picked up new in 1985.

    I can't yet speak about the video qualities of this receiver since I'm still in the process of building the home theater system that I want, but the audio qualities of this receiver are fantastic! You can tune this receiver to any musical tastes you have. They even put in an "unplugged" music option for those types of acoustic CDs you may have in your collection. You can set the soundstage up any way you like with this receiver. The THX is fabulous on music and definitely alone worth the extra money more that you pay over the next lower model in Onkyo's product line. Vinyl sounds wonderful if you were one of those people who religiously used your Discwasher on your LPs back in the 70s. If you've been watching this receiver for a while as I had, snag it now while it's still on sale before the price goes back. At the price right now, it's like you're getting free THX thrown into the deal.

    Pros: Worth every cent at full price. On sale, you can't find a better deal going right now, but that won't last long.

    Cons: None that I can see at the present time.

    Onkyo TX-NR737 - Great Receiver for the Price

    Written By EarlW, Arkansas on Tuesday, April 21, 2015

    Crutchfield Customer Review (What's this?)

    I bought this receiver to replace an aging Onkyo FX-SR805. I had three reasons to upgrade at this time; first I was out of HDMI inputs and needed more, secondly I wanted 4K upscaling and to be prepared for the changes coming in 4K security in the future, and thirdly my receiver in my office/shop did not have any HDMI technolgy so i wanted to replace it with the FX-SR805. The TX-NR737 runs a lot cooler and is smaller and weighs less than my the SR805. Installation was a breeze. Before I bought the NR737 I read several reviews which had some negative things to say about Onkyo calibration. All I can tell you is my experience has been nothing but positive. The calibration went great and I checked all the settings afterward and it was spot on. Sound is extremely good. I suspect if you compare most of the brand name receivers sound you or I would not notice a difference so look at the features offered and what fits your needs. For me, I was concerned about being 4K ready. That's my next purchase a 4K TV that's HDCP 2.2 Compatibile. Good luck, but you can't go wrong with Crutchfield.

    Pros: Great sound, improved picture and easy setup

    Cons: None thus far

    Audio Features

    7 Channel Amplifier: The Onkyo TX-NR737 AV receiver features a 7-channel amplifier rated at 110 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). The AV receiver's amplifier employs WRAT, 3-Stage Inverted Darlington Circuitry, H.C.P.S, and Optimum Gain Volume Circuitry for dynamic, detailed, clear sound.

    • WRAT (Wide Range Amplifier Technology): WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. A "closed ground-loop circuit" design is employed, in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers to immediately cancel the speakers' reflex energy and instantaneously send out the next signal. The same high current better manages speaker impedance fluctuations, which can negatively affect performance.
    • 3-Stage Inverted Darlington Circuitry: The AV receiver incorporates 3-Stage Inverted Darlington Circuitry into the front & center channels. This core Onkyo technology employs a low-NFB (negative feedback) design that makes the sound more natural.
    • H.C.P.S. (High Current Power Supply): Under the anti-resonant cover of any Onkyo receiver, you'll instantly notice the High Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power supply design and high-capacity filter capacitors, it delivers the large amounts of power necessary for reproducing the wide dynamics of movie soundtracks and the detail and clarity of your music.
    • Optimum Gain Volume Circuitry: Optimum Gain Volume Circuitry adjusts the gain so that less than half the amount of attenuation is needed, ensuring the signal never comes close to the noise floor. This protects the signal against noise, resulting in a dramatically clearer sound.

    Amplifier Assignment: The 7-channel amplifier can be configured in a variety of ways to match your type of speaker setup.

    • Normal (7.2ch): The Onkyo TX-NR737 provides 7.2ch surround in your main listening area. You can choose either Surround Back or Front Height speakers (but not both).
    • Front Bi-Amp (5.2ch): The Surround-Back/Front-High speaker terminals can be reassigned and used along with the Front terminals to bi-amp the front speakers, providing improved bass & treble performance. When bi-amping the front speakers the receiver is limited to a 5.2ch speaker system in the main room (no Surround Back or Front Height speakers)
    • Powered Zone 2 (7.2ch + Zone 2): In this configuration, you can connect Front, Center, Surround, Surround Back (or Front Height), and Zone 2 speakers to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back (or front height) channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power.
    • Dolby Atmos (w/ Firmware Update): The Surround-Back/Front-High speaker terminals are assigned to power a pair of overhead ceiling speakers or a pair of Dolby Atmos-enabled speakers to create 5.2.2ch Dolby Atmos surround sound. Zone 2 speaker can still be powered by the receiver in the configuration. When Zone 2 is off, all seven channels will be used in the Main Zone for Dolby Atmos. However, when Zone 2 is on, power to the Dolby Atmos channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power without Dolby Atmos.  

    192kHz/24-bit DACs + Dual 32-Bit DSP Processing: This Onkyo TX-NR737 is equipped with 192kHz/24-bit Burr-Brown DACs to decode and playback high-resolution recordings with less jitter and  clearer sound. The receiver also employs powerful and highly accurate Dual 32-bit processing DSP's (Digital Signal Processor) for better surround sound reproduction.

    PLL (Phase Locked Loop): PLL jitter-cleaning circuit technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves audio quality. Jitter-cleaning technology works both for digital signals input via HDMI and for digital signals converted from analog signals inside the receiver itself

    AccuEQ Room Calibration: Calibrating the sound to suit your room's acoustics is simple with Onkyo's AccuEQ auto-room calibration. Once you've connected your speakers, plug-in the included mic and wait a few moments as the TX-NR737 measures things such as speaker distance, type, crossover, and output, taking into account any reflections from your walls and floor. The system is designed specifically to by-pass your front left and right speakers. The system then optimizes the frequency response of the remaining speakers so you can enjoy balanced surround sound regardless of room shape or furnishing while retaining the characteristics of your front left and right speakers for optimum enjoyment

    Multi-Channel Decoding Formats: The Onkyo TX-NR737 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Dolby Atmos: The TX-NR737 receiver is Dolby Atmos (5.2.2ch) compatible through a firmware update from Onkyo's website. Dolby Atmos combines traditional home theater speaker layouts with either ceiling-mounted speakers or new Dolby Atmos-enabled speakers to create a plane of sound above the listener. The impact of either in-ceiling or Dolby Atmos-enabled speakers is breathtaking. Your room fills with realistic, multidimensional sound that places you directly in the center of the entertainment experience.

    • Ceiling Mounted Speakers: Ceiling speakers are used for maximizing effects in Dolby Atmos listening mode. Install these speakers midway between the position just above the listening position and the position just above the front speakers, or simply install them just above the listening position.
    • Dolby Enabled Speakers: There are two types of Dolby Enabled Speakers; one is to be placed on the top board of other
      speakers such as front speakers and surround speakers; the other is integrated within the front or surround speakers. Dolby Enabled Speakers are designed with their output facing toward the ceiling to create an elevated audio effect in the Dolby Atmos mode by providing sounds echoing off the ceiling.
    Note: Globally, more than 100 cinema blockbusters have been released featuring Dolby Atmos soundtracks in the past two years, and many more are on the way. Major Hollywood studios are partnering with Dolby to create home video versions of both current box office releases and previously released favorites for release starting in 2014.

    Dolby Surround: Dolby Surround offers an enhanced cinema experience to your Dolby Digital (Plus/TrueHD) and DTS (ES/HD) movie soundtracks using your existing 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".

    THX Select 2 Plus Certified: The TX-NR737 AV receiver is THX Select 2 Plus certified. Founded by George Lucas, THX develops stringent standards that ensure movies are reproduced in movie theaters and home theaters just as the director intended. From early design concepts to product rollout, THX works with its manufacturing partners at each step of product development. Every detail is meticulously mapped to the THX performance standards. And THX engineers spend countless hours testing and analyzing each product for sound quality, usability and interoperability. The result of this collaborative process is a THX Certified receiver, amplifier or pre-amplifier designed from the ground-up to present your favorite movies, music, and games in 5.1ch to 7.1ch surround sound loud and clear at studio reference volumes. THX Select 2 Plus is specified for rooms where the screen-to-seat viewing distance is 10-12 feet and the room volume is 3,000 cubic feet or greater.

    • THX Surround EX: The THX Surround EX mode further expands 5.1ch sources for 6.1ch or 7.1ch playback.
    • THX Loudness Plus: THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel levels and frequency response. With THX Loudness Plus, home theater audiences can experience the rich details in a surround mix at any volume level.

    Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:

    • Orchestra: For classical or operatic music.
    • Unplugged: For acoustic instruments, vocals, and jazz.
    • Studio-Mix: Suitable for rock or pop.
    • TV Logic: Adds realistic acoustics to TV shows.
    • Game: The receiver offers four different Gaming modes - RPG, Action, Rock, and Sports.
    • All Ch Stereo: Stereo sound from all speakers. Ideal for background music.
    • Full Mono: All speakers output the same sound in mono.
    • Theater-Dimensional (T-D): Theater-Dimensional circuitry takes the complexity out of conventional surround-sound setups and lets you experience the excitement of surround sound from as few as two ordinary speakers. Theater-Dimensional's unique multi-speaker modes let you place up to five speakers conveniently by the TV, for the most realistic virtual-surround sound possible.

    Direct Mode: In Direct mode, audio from the input source is output without surround-sound processing. This mode delivers pure sound with minimum sound quality adjustment and filtration.

    Surround Parameters: The Onkyo TX-NR737 lets you tweak and fine tune specific surround sound modes to suit your preference.

    • Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust; Panorama: (broadens the front stereo image to the surround speakers to provide a wraparound effect), Dimension (allows you to move the sound field forward or backward), and Center Width (allows you to adjust the width of the center channel).
    • Center Image: In the Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
    • Pro Logic IIz Height Gain: The Height Gain Control in Dolby Pro Logic IIz enables the listener to select how much gain is applied to the front high speakers. There are three settings, "Low", "Mid" and "High", and the front high speakers are accentuated in that order. While "Mid" is the default listening setting, the listener may adjust the Height Gain Control to their personal preference.
    • Listening Angle: While listening in the Theater Dimensional mode you can adjust the listening angle to either Wide (if listening angle is 40°) or Narrow (if listening angle is 20°).

    Audio Enhancements: The Onkyo TX-NR737 receiver provides various audio enhancements to deliver a high-quality listening experience every time.

    • CinemaFilter: Using the CinemaFilter you soften overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
    • Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz and analog input signals.
    • Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.

    Bass Management: The Onkyo AV receiver offers Tone Control and Phase Matching Bass technology to get the most bass impact out of your system.

    • Tone Controls: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-NR737 from -10 to +10 dB.
    • Phase Matching Bass: Onkyo's Phase-Matching Bass optimizes low frequencies while preserving mid-range clarity. This means that powerful bass plays back with clear vocals; it doesn't overpower them.
    • Double Bass: You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer.

    Volume Setup: The Onkyo AV receiver provides the following volume settings.

    • IntelliVolume: With IntelliVolume, you can set the input level for each input (+/-12dB) selector individually. This is useful if one of your source components is louder or quieter than the others. This function does not work in Zone 2.
    • Maximum Volume: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 30-79 (max), or Off (disabled).
    • Power On Volume: Use this feature to set the volume level when the power is turned on. You can choose between Last (same as the volume when the unit was turned off), Min (0), or 1-79.
    • Headphone Level: With this setting, you can specify the headphone volume (+/-12dB) relative to the main volume. This is useful if there's a volume difference between your speakers and your headphones.

    Audio Inputs/Outputs: The Onkyo AV receiver offers a variety of analog and digital audio inputs/outputs.

    • Assignable Digital Inputs: The Onkyo receiver is equipped with one optical digital input and two coaxial digital inputs. All three digital inputs are assignable. You can choose auto decoding , PCM, or DTS for the digital audio inputs. Auto will decode the signal in its original form (Dolby Digital, DTS, PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS formatted sources.
    • Phono Input: The Onkyo AV receiver is fitted with a Phono input and ground terminal for connection of a turntable (MM).
    • Binding-Post Speaker Terminals: There are color-coded binding-post terminals for all speaker connections - Front, Center, Surround, Surround Back/Front Height, and Zone 2. The binding post terminals will accept bare-wire, pin-connectors, and banana plugs (single/dual). Use 4- to 16-ohm speakers.
    • Dual Subwoofer Outputs: The receiver is fitted with two subwoofer outputs to connect dual powered subs for extra bass. The dual outputs share the same input signal and are not discrete.
    • Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.
