Overall happy

Fit the bill for what I was looking for. Sound is great! Set up was pretty easy, and lots of hdmi inputs. The remote works great to control other devices like tv and set top box. Plays Spotify well wirelessly through Bluetooth, however it didn't want to play it when I hooked up my phone to it through the usb cable?? I also couldn't play music from a different source while watching tv?? Might be my hookups?? I will keep trying to figure it out while enjoying it. Great product!

Great Value

Has so many features and more than I would ever use. Takes a bit of getting use to for the remote but better than the frustrating thumbwheel on the remote and input panel switch from my old 5.1 Yamaha RX. Like having all controls on front panel. The Onkyo sounds very good to my old ears with my Paradigm 7s and 3s after a dozen or so years. Even allows for biamping on my 7s. Only problem I had even after tech support help was not being able to get sound from a Netflix broadcast on my Toshiba 3d TV. Not fair to rate this receiver so low because one user expected subs out to be powered outlets...tell me a unit that does...should have done more research before blaming Onkyo to death.

Great audio performance but difficult to read

The Onkyo TX-NR636 is the home entertainment centre-piece I've been looking for all these years. It has a phono input that allows me to listen to my old records in 5-channel stereo. It has enough HDMI inputs for a couple video streaming devices and my WD TV box. Setup is relatively easy. I coupled the stereo with some new Cambridge audio speakers that are not too obtrusive. These match well with the sub-woofer and my legacy Celestion speakers. Sound is great. I can hear the quality and crisp audio response. However, the visuals need work. The dark-grey on black lettering on the main-unit are almost impossible to read without great light (flash light on the phone). The versatile, multi-function remote is set-up to control all my devices but it's so cluttered and the font is so small I have trouble finding the right features. I guess the system was designed for people with great hearing and superlative vision. That's not me.

Excellent Mid-Range Receiver with Top Features

This is the second identical Onkyo model I've purchased. I bought the first one from Future Shop about 6 months ago for the bonus room. After learning about all the features it has to offer as well as reviewing the sound quality, I could see no viable reason why I shouldn't pick up another one to upgrade the "Man Caven" home theater setup in the basement. Wow. The sound is crisp and clear, the low end frequencies are thundering and deep. The AcuEq feature did a very good job calibrating my 10 x 14 bonus room, but did not accurately detect the correct frequency for the identical speaker brands in the basement setup. Only difference between the two environments are 5.1 upstairs and 7.1 downstairs as well as a larger room downstairs (room size is likely the root cause). Be sure to perform the firmware upgrade even if you are not planning to upgrade your system even if you don't plan on taking advantage of the Dolby Atmos feature. The firmware upgrade introduces a new listening mode called Dolby Surround and replaces one of the shipped Dolby modes. This new mode will provide a greater surround effect with whatever speaker configuration your existing system has. Very well done in my opinion. The difference is night and day compared to all the other modes. I've heard that Onkyos have a tendency to overheat and burn out it's circuit board. Yes it runs warm, but it's pumping out hundreds of wattage and doing all the heavy lifting of your system. I'm not at all concerned with the heat (bonus room receiver is in a closed cabinet with an open back). Just because I'm meticulous about my A/V equipment, I purchased a little component fan called CabCool which sits on top of my receiver's grill above the power supply and tuuns on and off automatically when the temp is above 25 degs or so. Excellent component. I highly recommend it!!

nice reciever

Bought about 6 months ago. Seems pretty good, havent tried all the capabilities yet or customer service. One little glitch i have noticed. I have apple tv running through the cable/satellite input. Sometimes it switches out from this input to a blue blank screen before trying a couple times to reset itself. I can here it clicking like a restart or reboot. It then goes back to viewing the proper input. Seems kind of like a protection circuit kicks in momentarily.

Future proof

Most future proof purchase that you can make......I bought it over the Sony because of the Phono jacks.

  • from Kitchener, ON


I purchased this unit on sale and replaced my Yamaha HTR 6060 and was not disappointed ....better sound, power and up scaling of some of my Blue/DVD is amazing everything looks crisp. I set this up with on an Epson projector ( 108 inch screen) with Polk Audio Monitor 10, mission freedom and a cerwin-vega centre all 10+ years old and sounds fantastic but the icing on the cake is what I couldn't do with the older Yamaha(HDMI out) was I hooked up an old VCR through Video and it played out the HDMI output .....some issue with the firmware updating and reaching customer service is a little concerning but I am happy with the sound

I'm quite happy with the new 636 receiver that I recently purchased. The sound is good and the Geek Squad did a great job of setting up the surround sound for me.

  • from Sault ste Marie

  • from Windsor, ON


Very discrete 7.1, listening modes best idea. Looking forward to more 5.1.2 Blu-ray movies to enjoy " Atmos" at home.

  • from Calgary, Alberta

It's a beast!!

Top notch for the money! Pros: - Epic Sound quality. Enough watts to kick out some serious sound with the right speakers - Dolby Atmos is super neat. Bought a couple Onkyo speakers that reflect the sound off the ceiling so I don't have to install speakers to get the same effect! - So many HDMI inputs! Seriously.. 7! Oh, and 2 outputs! - 4K ready! (Don't need it yet, but now I'm ready) - 3D ready! (same) - Bluetooth range is great! Almost makes it to the top floor, from the basement. - WIFI and Ethernet support for DLNA - Built in fan to keep it cool Cons: - My neighbors hate me. Great purchase! Would do it again and again!

worst reciever ever!

I bought the onkyo tx-nr636 reciever because I wanted dolby atmos, it was a great deal, and I was very excited about getting it! But after one day I had shown its true color, hdmi stopped working, my screen was flickering and blacking out, after reading all the trouble onkyo hdmi boards has I wasn't surprised I had trouble, after calling and waiting for god knows how long, customer service told me to turn of a bunch of features, i wantd the features thats what I bought it for!! I never want to hear about onkyo products again,

Very Impressed

I bought this receiver to replace a still working 10 year old Yamaha. I have always used Yamaha but thought I would try this Onkyo as it has all the modern features I was looking for. HDMI 2.0, 4K, Bluetooth, etc. I am very happy and impressed with this Onkyo TX-NR636. I also bought the Onkyo Atmos front height speakers as well.

  • from Mtl

Hard to beat for the price

This AVR is great for the price & like the other comment says you need to do a little homework, I really don't know of very many AVR products that have supplied power for the sub, & if it did it would be much larger, not to mention more expensive, most subs are powered anyways for home theater unless you were hoping to use your old car stereo sub what's the big deal.

An excellence receiver for the price and size. I needed something that would fit inside a sealed cabinet that is only 15" deep. At just 12.9" deep, this receiver fit the cabinet perfectly with wiggle room for all the wiring and I can keep the cabinet closed. If you want to go this route, make sure to vent the cabinet well to avoid overheating. Set up with a Bose Acoustimass 10 speaker system, this receiver has excellent sound quality including deep bass which can really bring movies alive. For setup - they have an advanced on line manual on the Onkyo site for great detail and this may be necessary as the manual in the box is a bit lacking. I set this system up with a harmony remote as well, which allows me to control it through the closed cabinet without issue. This is a clean setup with amazing sound, which was exactly what I was aiming to build.

Good value for the money

I am only writing this review because I feel that the current "rating" is skewed by a completely unfair negative review given by someone that obviously didn't do their homework prior to purchasing this item. For the money, this is an excellent product. Yes the design isn't super flashy, but what AV/REC/AMP is? These components are designed for function over form as they should be. The NR636 has no less than 7 HDMI inputs...fantastic! Think about it, DVR, PS3, PS4, Xbox 360, Xbox One, IPad...and you still have one input left. Easy to set up, easy to use, one cable going from the unit to the TV. Sound quality will of course depend on the speakers you are using, I have a decent mid-range 5.1 set up (with a powered sub) and it sounds great. Would I use this unit to set up a 7.2 10 seat home theatre...probably not, but for a 5.1 family room set up it does the job nicely.

Deceptive Advertisement of Product Description

I feel ripped off by Onkyo. 1) If you think you are buying a receiver with built in amplifier, think twice. They say it's a 7.2 system, buy they only provide amplifiers for the 7 speakers. I found this the hard way by discovering that I either have to buy powered subwoofers or buy a separate subwoofer amplifier that is at least $[...] and on the average costs $[...] for a decent one. No one explained as part of the product description that this product requires an additional amplifier. I encountered this problem when I wanted to connect the receiver to my in-wall subwoofers which are 300 watts each. 2) The manual that came with the system (and the online PDF version of it) is so shallow and superficial that you would think was written for a FM radio. They don't at all get into the details of the vast, rich features of the system, such as speaker system configuration, and wifi, blue-tooh, or any of the other multitudes of features. After all I only bought this system because of its rich feature lists. I am very disappointed with the poor job ONKYO's management has done in handling the user-consideration and honest marketing of this product. My recommendation: Don't buy this product find one that has an amplifier to drive each of your speakers including your passive subwoofers otherwise you have to spend another $[...] to get this system to do its job.
