I bought this receiver because I needed a new one to pair with my 4K TV (75" Samsung Q80T). After hemming and hawing for too long, there weren't many options to choose from unless I wanted to spend $2000+, but I'm happy with this purchase.Installation and set-up was easy, but make sure you go through the menus and verify that things are set right. There's a lot of settings that I haven't looked at (for Alexa, Sonos, etc. cuz I don't use them) but overall things are pretty intuitive.One thing I thought was interesting was that this receiver has some kind of pre-set settings for Klipsch speakers and subs which are completely left out of the specs and info sections on websites. I have 2 Klipsch R-12SW subs (which are great!!) and will probably be getting some ... MoreI bought this receiver because I needed a new one to pair with my 4K TV (75" Samsung Q80T).

What for? Well, it's actually great for my situation because I can run my PS5 through one port and into the one (and only) 120Hz port on the TV (HDMI 4), and then use the other receiver HDMI Out for the e-ARC to/from the TV (HDMI 3). If you are going to use both HDMI Outs, make sure you have the receiver settings for that correct or your devices will act...weird.

So I just picked this up today. I went to a BestBuy in one town and saw the model last night, while they did not have it in stock, they did have a model on display. I went to another BestBuy today and picked it up. The display model had the four sound posts and alligator clips as shown in the photo. However, the receiver I purchased had all sound posts with no alligator clips. I am not sure why the demo had one connection and the one I got had another. The box showed sound posts, so, if that is important to you, look for that.Setup was easy, sound is excellent. I have only had this a matter of hours, so I cannot comment on longevity, but I cannot imagine having long term problems. I would definitely recommend this product.

One of the main reason I picked this up was for the 4K @ 120Hz, VRR and HDR and doesn't disappoint! So previous reviews stating it doesn't support certain functions must have been resolved in firmware updates! I was pleasantly surprised that it continues to pass-through when I use my headset and keep the receiver off.Sound quality is actually pretty good and much improved from my old Yamaha. My only extra little wish was if there was a little more wattage but I already knew that from the specs...I would actually give this 4.5 stars but no half-star option

Negative 5 stars.Easily the worst purchase you could ever make. The company won't support its products.This won't stay on the input selected. In fact, it suddenly now changes to Chromecast when I turn down the volume. When I reselect the cable/satellite, the screen is green. I have to reboot everything and start over. I am tired of resetting this stupid thing to factory settings and going through setup once a month. I hate that they have my money. This is less than a year old, and I want to throw it in front of a bus.Don't buy Onkyo.Best Buy was no help either.
I purchased this, wanting really to purchase the Onkyo TX-NR7100, which has still to hit the shelves but has been unavailable for months now. The NR5100 would suffice, although it it a bit limited on HDMI inputs, they were sufficient for me. I wanted a future-proof product to replace my Integra (aka Onkyo) DTR-40.3 which sounded great but did not support 4k video.My grudge was that for the center and surround channels it just had spring speaker clips, not screw terminals and I associate them with budget receivers. So I bit and bought this at Best Buy.ProsAll the inputs and outputs for my setupSufficient amplifier powerFeature -rich, including 8k videoNice menu system, albeit a little confusing'Works with Sonos'.

So I bit and bought this at Best Buy.ProsAll the inputs and outputs for my setupSufficient amplifier powerFeature -rich, including 8k videoNice menu system, albeit a little confusing'Works with Sonos'. Don't underrate this. As soon as you select a Sonos playlist on your (phone) app the amplifier will power up and select the Sonos audio input and volume level you had previously set. That's nice, but even nicer is it does not introduce a processing delay in the audio. I was vexed by my Integra and previous receivers. They would add a few hundred milliseconds in the audio path if you applied the 'All-Speaker' audio setting. The only way to prevent this was to limit the Sonos audio to stereo, in the room where you had installed rear and ceiling speakers! The delay would cause a horrible echo when you walked into another room where a different Sonos was also playing. I had to use a 6 channel pre-amp to fool the Integra, but it is not necessary on this unit.ConsThose spring clip speaker connections are really second rate.Not a great AccuEQ. This room-sound calibration system comes in different recipes. This was a one-location low-end solution. I was used to placing the supplied microphone in different locations during the setup process, to equalize the sound settings to accommodate more than one person seated in the family room.Noticeably lost is your ability to review the settings it arrives at as well. You cannot review the equalizer settings it has applied.Sonos music sounded pretty good, but the amplifier sound playing a movie felt 'cold'. OK, not great English, but the sound was definitely off-par. I tried recalibrating, but in the end, the immersive sound delight I was pursuing simply felt 'not there'.I ended up returning it and managed to purchase a reconditioned Onkyo TX-RZ840 directly from the Onkyo website. It is sweet, and well worth the extra dollars.
purchased this last minute as my Sony receiver died after 4 yrs. and the XBR 65" I bought died after 2 yrs. Needless to say, switched brands. ONKYO sounds better, more options, quick set up and recognizes other devices quickly and accurately. Havnt completed full set up with Google but will do soon enough. Just been enjoying the great sound.a lil more expensive than I wanted to pay,... but... you definitely get what you pay for with ONKYO. no regrets.
This is a great receiver if you do not need two zones to be independently volume controlled. In my home, I have two outside speakers that are wired into this receiver as all the wires come to one spot in my home. I wanted the ability to be able to be playing content inside as well as content outside. In trying to turn the outside speakers louder, the only way that this could be done is if I also turned the inside speakers louder as well. It can also be done if I switch the receiver to only play sound on the outside speakers. Because this receiver doesn't have true multiple zones for the speakers, this is not possible. I talked with best buy support as well as the best buy install guys to try and figure this out with this model, but they stated that this is not ... MoreThis is a great receiver if you do not need two zones to be independently volume controlled.

That being said, this is a great receiver that can push 4k at 120hz as well as 8k so if you need it for pushing your PS5 graphics, it can do that with no problem. However in my situation, I am returning and purchasing the higher model.
Well, this is a great receiver. I purchased a $900 Denon immediately before this one, and returned it because it just didn’t have the sound profile that I needed. Once this one was configured with a microphone and a custom EQ I cannot believe the difference in sound quality for a much cheaper price than the Denon. I pair this with a 5.1 Polk speaker system. I have a JVC subwoofer on the side that I hardly even need because this produces such nice bass. If you were considering the Denon over this one, do yourself a favor and get this one.
I will say at the least this receiver sounds incredible when it works. It is hooked up via CEC meaning when the TV is turned on, it also switches on the the receiver. Problem is there is no sound coming from the receiver. This happens every time. I'd have to unplug the receiver, count to five and plug in back in and then it will work. This became a real hassle after awhile, so I decided to disable the CEC function on the TV and receiver to turn everything on manually. That did not resolve the issue. Same problem. I'd have to unplug and plug it back in to work. I did a firmware update to no avail. This is unacceptable to pay this much money for a product that does not work properly. I must have gotten a lemon, because Onkyo is a reputable brand and the customer ... MoreI will say at the least this receiver sounds incredible when it works.

I must have gotten a lemon, because Onkyo is a reputable brand and the customer reviews are pretty good. Now I have to go through the headache of packing this up, pay for shipping, and pay for insurance to send it to an authorized Onkyo service center. I wish I had gotten Geek Squad Protection. Lesson learned.
GREAT receiver!! This is the third Onkyo receiver I’ve owned and it’s outstanding. Upgrading from a 12 year old Onkyo (still works great just older hdmi that won’t support 4k). It’s powering a 5.1 system and even at only 80 watts/channel it’s loud and clear. Calibration and room correction are a good starting point but you will need to tweak the settings to taste (calibration set my fronts to a 40hz crossover even though I have a sub) Updates are easy with wifi. NOTE: Old reviews talk to spring clips for speaker connections however this model has been updated to binding posts. Additionally, this model does not support HDR10+ only supports HDR and Dolby Vision. IMO not a game changer unless you want to spend another $100 for the NR6100
