AVR-S770H - My first AVR and my first Denon - works great with Directv and Fire Stick
Style: AVR-S770H
This review is for the Denon AVR-S770H. I was apprehensive about buying an AVR for my main TV. I've always used a soundbar and was happy with the results. I assumed that adding an AVR would make things finicky and complicated. I'm happy to say, that is not true. This Denon has been fabulous.
My requirements for a home theater receiver were/are the following:
1) Ease of use and NO additional remotes to our current set-up (family needs, I'm not a bachelor!)
2) I need the ability to connect 2 zones: the TV room and I have a pair of outdoor speakers on the patio
First, as to the remote situation, I use Directv and I use an Amazon Fire Stick 4k. My old set-up was super simple. I picked up the Directv remote and hit Power. That turned on the TV, the Directv box, and the soundbar (since it was connected to the TV ARC port). Simple. If I wanted to change over to the Fire Stick, I simply used the same Directv remote to change the input and then used the Fire Stick remote from there.
I'm happy to say the Denon has made things even simpler. Not only does the Directv remote turn on/off the TV, Direct box, and the Denon receiver but now I don't even have to bother switching inputs. If I pick up the Fire Stick remote and hit the Home button, the Denon senses that and immediately switches over. Likewise, if I pick up the Directv remote and hit a button, the Denon will switch back over to Directv. So that is an actual improvement.
By the way, in order to get the Directv remote to turn off the Denon, don't worry about trying to program the remote via the Directv menu (I tried all the codes and failed). Instead, go to the Denon setting menu. Choose Setup> Video> HDMI Setup. Change the "Power Off Control" to "Video" or "All". Now the Denon will turn on/off when the TV does (using the Directv remote).
My second concern was operating a second set of speakers via Zone 2. That also works perfectly. Now when I step outside to sit on the patio, I simply hit the Zone 2 button on the front of the Denon. I can use my phone to play music via the Denon's built-in Bluetooth.
Some users need to be aware: in order to operate Zone 2, the receiver needs to be switched from 7.2 channel to 5.1 + Zone 2. That's perfectly acceptable for me since my TV has only front L & R speakers and a subwoofer. So I'm not even using the full capabilities of the 5.1. If you need 7.2 and a second zone, you need to find a different AVR.
In sum, I bought this Denon with some trepidation and thought maybe I'd have to return it. Instead, it does everything I want and then some. Of course, it sounds great too. I'm so glad I switched from the soundbar.

Wow!
Style: AVR-S770H
I had an Onkyo 5100 for a few years and experienced lots of issues with the UI over HDMI but after many many firmware updates they seemed to have resolved that and it had a great sound. Recently however the receiver started to turn itself on for no reason and I felt that it was a fire hazard. I bought this unit as a replacement and so far it is flawless. I believe that this receiver sounds even better and hopefully more reliable. The Atmos sound is excellent.

A firmware nightmare
Style: AVR-S770H
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.

Turned me into a Denon fan.
Style: AVR-S770H
I've only ever used Sony components for over 30 years. My latest Sony receiver experienced some problems. When I saw how much it would cost to repair it myself (circuit board swap), I decided to look at what else is on the market. This receiver costs less than the Sony replacement part with S&H. When the box showed up with full-sized, color pictures of the front and back of the receiver, I knew I was going to become a fan. Opened the box and one of the first thing I saw was a sheet of colored cable labels that includes labels for the components that will be plugged into the receiver. Pull the receiver out and see that the ports are color-coded too.
Color-coded ports and labels is something I'm very serious about. I worked for years as a field engineer for a Fortune 100 computer equipment manufacturer. The low-end components started at $100k. For years, I tried - and repeatedly failed - to convince the product design teams to color-code the ports. To find everything I had fought for in a consumer-grade device was a dream come true.
Not satisfied to make the cabling process as easy as paint-by-numbers, Denon embedded a video setup routine in the receiver that walks you through setting up your speakers, running the cables, and plugging in every single cable. The audio calibration process far exceeds what the Sony receivers do. In the box is a microphone with really long cable and a cardboard microphone stand you can easily assemble and disassemble. During the lengthy calibration, you place the microphone in 3 different listener positions - twice - for a total of 6 room readings.
Adding components to each HDMI port was also just as easy and detailed. I have a small 'home theater PC' that it detected and gave me multiple names to assign to the port (Sony port names are fixed). I plugged my Xbox into the Game port and the top name on the list was Xbox.
In no time, my home theater was back to normal - and I haven't even download the user manual to learn how to use the other features or go into the advanced settings.

Good with two annoyances
Style: AVR-S770H
It works for what I need (Xbox Series X FreeSync to an LG C3 TV and 5.1 speakers), but there are two annoying bugs. When it first turns on or changes to an input with a different frame rate, the content briefly flashes on the screen, then it goes black, then it goes back to the content taking a good 3 seconds before it's usable. And when you hold the volume buttons on the remote they go super slow for a bit then suddenly ridiculously fast. Not deal breakers, but it does get old after a while. Also no bi-amping, which I knew beforehand, but still a let down.
