AVR-S770H 7.2 Ch Home Theater Receiver - 8K UHD HDMI Receiver (75W X 7), Wireless Streaming via Built-in HEOS, Wi-Fi, Dolby TrueHD, DTS Neural:X & DTS:X Surround Sound, Bluetooth Amplifier

I traded up to a Denon AVR-S970H from an Onkyo TX-NR636 that was slowly dying. They have mostly the same power rating and features. The setup was fairly straightforward with a few little quirks that, until you understand the operating logic, are common when you change brands. This receiver is advertised as a 7.2 channel system. It also advertises a powered Zone 2 output. However, you can't have both at the same time. The powered Zone 2 outputs use re-assigned Back speaker connections and the system then becomes a 5.2 system. Since a 5.1 and powered Zone 2 is what I already have, this fit my needs exactly. If you want a 7.2 channel with powered Zone 2, this receiver can't do that. Most of the new 7.2 systems seem to have a separate pre-amp Zone 2 output, which requires either an additional external amplifier or powered speakers to drive the Zone 2 sound. The use of their HEOS app to access on-line music streaming is definitely different, but seems to work ok. The additional Denon Remote app operates the receiver via Wi-Fi, which also works ok. Nothing fancy, though. The Bluetooth transmitter isn't available for wireless headset use when either the MAIN Zone or ZONE2 are sourced by HEOS, which prevents you from streaming on-line music from the receiver. TV Audio, Blue Ray, USB, CDs, etc. can all still be Bluetooth'd out, just not a HEOS source. I was stumped about this issue and called tech support. They answered the phone immediately and quickly answered my question. Not the answer I wanted, but that's how it works. If your TV or Blue Ray player can stream Pandora, Spotify, etc. app, you can feed that to the receiver and Bluetooth it out to headsets, so there is a work-around. The sound quality is very good and is marginally better than my old Onkyo. The Denon has some audio tuning features not on the Onkyo (Dynamic EQ, Dynamic volume, MP3 Rendering, and others). I have a remote reading temperature sensor in my stereo cabinet. The cabinet with an Onkyo always ran about 90-92dF. This is fairly hot and can impact long term reliability. To limit that high temperature, I had added 4 little computer fans to help ventilate the cabinet. So far, the highest temperature I've seen the Denon run is 80dF, a big difference for the same sound volume. Not sure why that is, but I like the result. I can probably remove the cooling fans. The one thing I wish the Denon had is a programmable TV power button on the remote. This missing feature forces me to use a 2nd remote every time I turn the system on. Overall, I would definitely recommend this receiver to anyone looking to buy in this price range.

An amazing and easy to use AVR. On screen set up including room calibration provided a wonderful audio experience. This is my second Denon and I have to rate them as top of the line. Amazon Delivery was a problem though, they seem to be losing their advantage especially to Prime members who are told an arrival time at the time of order only to miss that regularly. I have experienced multiple times.... Unacceptable, sucker us in to make a purchase based upon receival date and then not provide that service.

This receiver is fantastic. I have it in my bedroom connected via e-arc hdmi to my Amazon firetv powering 5 klipsch reference speakers and klipsch home theater sub. There's zero hiss or static. It sounds great and the bluetooth connects instantly. The included mic was able to set all the speaker distances for me. The menu can be a little intimidating, but after an hour or so I was able to figure it all out. I did download the manual, but didn't really need it. I would buy it again in a heartbeat. I think you'd be hard pressed to find another receiver that's this good for the price. Denon makes a fine product.

The Denon AVR-S670H has been a solid upgrade for my home setup. It’s got great sound, and for the most part, it’s been easy to use. After spending some time with it, though, there are a few things that could definitely be better. Setting it up was pretty simple. The on-screen guide helps, and it didn’t take long to get everything connected. Streaming music has been a breeze, especially with Spotify and TIDAL. It also works well with our Google Home system, so I can adjust the volume or switch inputs with voice commands, which is convenient. One thing I like is the customization options. You can rename inputs and adjust speaker settings pretty easily. It gives you control over how things are set up, and that’s a nice bonus. But, there are a few downsides. To get the most out of the receiver, you have to connect it to your TV through an ARC (Audio Return Channel) setup. If your TV is older and doesn’t have ARC, you’re going to lose out on some features, like running your TV’s audio through the receiver. It’s a bit annoying if you’re not ready to replace your TV. Another issue is that everything has to be done through the remote and the TV screen. Want to adjust the equalizer or set radio presets? You’ll need the remote and TV for that. There’s no option to do these things directly on the receiver, which is inconvenient for quick changes. There’s also a pretty limited number of outputs. You’ve got an HDMI output for your TV and one RCA output, but that’s it. If you’re looking to connect other devices, you might be out of luck. One thing that’s been especially frustrating: I haven’t found a way to play audio from the receiver over my Google Home speakers. I’d love to listen to a vinyl record and have it play throughout the house, but so far, I haven’t been able to make that work. It’s a bit of a letdown if you’re hoping for whole-home audio. Overall, the Denon AVR-S670H sounds great and works well for streaming music and movies. It’s been reliable, but if you’ve got an older TV or want more flexibility with controls and outputs, you might run into a few headaches.

I love this receiver. I previously owned the Denon AVR-S660 and I loved that as well but ultimately ended up upgrading to this one to get a little more output power. I'm only using it at 5.2, so I'm not using all 7 speaker channels - but I love it. Good power output and very clear audio. Plenty of Dolby and DTS surround modes. Bluetooth connects easily and reliable. I utilize the eARC when using apps on my smart TV and have not had any issues at all. I manually tuned mine, but it does come with that wired mic thing for the auto setup. Onscreen menus are easy to understand and not overly complicated. I love that when I play my turntable on this receiver that it allows the option to pick a 2nd source for video - meaning I can listen to my turntable through the receiver while watching television that is passing through the receiver - so I can listen to vinyls while watching the ball game. PERFECT. If I had to put a negative on this, I'd say the 2nd zone option that it gives you is a little wonky. The 2nd zone option only exists if you are using 5 channels and not 7. If you are using 5 channels, you can wire in 2 speakers to those 2 unused channels and those 2 unused channels would serve as "zone b" which you can turn on/off as you wish to play music in 2 rooms at once if you wish. I found there to be a little lag of a fraction of a second between the 2 zones, so if the 2 rooms were right next to eachother and music from room 1 could be heard in room 2 and vice versa, it sounded weird because they weren't completely in sync. Maybe that could have been tweaked, but I already had an external speaker selector in place from my previous receiver so I just went back to using that. Short of that issue though, this receiver has been excellent. Clear audio. Powerful audio. Easy menu navigation and setup. Plenty of Dolby & DTS options. WiFi, Bluetooth and ARC have all been reliable.... Very happy customer here.

This piece of garbage has a mind of its own. I bought it because I needed an HDR friendly device and it was highly recommended on more than one receiver list and went for a decent price. In strictly audio terms it is a nice machine, though I wouldn't say its features are extensive. However, IT decides when it wants to do things. It randomly goes to zero volume without me touching anything (around once a week on average). It randomly decides not to give me a picture when I turn it on. This has improved since the last firmware update. We are down from almost 20% of the time to slightly less than 10%. Yes. You read that correctly. I have to turn it off and then on again, sometimes more than once before anything besides a brand name will show up on my TV. It is supposed to have a screensaver but that never comes up unless they consider the stationary brand name a screen saver. I have owned this thing for over 6 months and actually seen a screensaver with animation twice. I have to turn my TV off if I am going to be away from it for any amount of time. It has had plenty of opportunity. The bottom line is that the people who write the firmware (operation software) don't seem to know what they are doing because this device is terrible at detecting REAL events and performing the necessary actions. As a software/media developer, my primary device is a PC but I have been using PCs with receivers for decades and never had these kinds of problems. Oh yeah... and the latest estimate of a firmware download is over 10 minutes.

Denon makes great audio equipment, and this Denon AVR-S570BT is no exception. After 12+ years of daily, faithful use, my Pioneer AV receiver bit the dust. I researched many quality "budget" AV receivers (to make the wife happy...lol), to replace the Pioneer receiver, and a lot of reviews and recommendations came up with the Denon AVR-S570BT. This Denon AV receiver is very intuitive, and easy to setup. It also has a LOT of features in this lower price range. This Denon AV receiver powers all 5 of the passive, original Pioneer Andrew Jones Design speakers (the subwoofer is self-powered) in my 5.1 surround system very well, and with great clarity. No, this Denon AV receiver won't blow the roof off the house, but it does get very loud, even with inefficient speakers, as the Pioneer speakers are, with an 84 db to 87 db sensitivity rating. However, the Pioneer speakers are 6 ohm, so that helps to increase this Denon AV receiver to 90 watts per channel, instead of 70 watts per channel at 8 ohms. This Denon AV receiver also seems to run a lot cooler than the Pioneer receiver it replaced, especially at higher volumes. This Denon AV receiver has just enough "bells and whistles" for my needs, as I really don't need 7.2 surround capability, Dolby Atmos, or WiFi features that come with the more expensive Denon AV receivers. Although, the included Bluetooth connection does come in handy, and it works very well with Samsung Galaxy Smart Phones. The automatic speaker calibration and setup is pretty accurate, but it also allows tweaking to individual sound tastes. There are probably features and modes of this Denon AV receiver that I will never use, but it's nice to know they are included just in case I need them. Overall, I highly recommend this Denon AVR-S570BT for anyone that is looking for a high-quality "budget" AV receiver. Just know that it does not have all of the newest features of some of the more expensive Denon (and other brand) AV receivers. However, this Denon AV receiver serves its purpose for me quite well, and then some. Only time will tell regarding durability and longevity. However, Denon does make quality AV receivers, and if I can get the 12 years out of this Denon AV receiver that I did out of my previous Pioneer AV receiver, I will be a very happy camper. So-far-so-good, though.

Let's start with the good stuff. It sounds great and it does everything I want it to do. I'm happy I found a 5.2 ch AV receiver with HEOS, anything over 5 channels would have been too involved for me. Now for the no-so-good stuff. It hums and it is noticeable. After a little bit of troubleshooting, I found out the noise was not coming from the speakers and the receiver does not produce an audible hum by itself, but something in the receiver vibrates when it's powered on and it resonates with the cabinet which produces a very noticeable low hum. I added some vibration isolating pads to the feet, that almost completely got rid of the noise. This next item is not a big deal and is likely an issue with any "smart" electronics. It can be buggy at times. I recently had to unplug the unit because it was producing no sound. It worked fine after. Lastly it's HEOS. It has so much potential and actually works alright, but it can use a lot of improvement in the user friendliness department.
