Easy Set Up and Great Sound Distribution
Style: AVR-X3800H
I replaced an old Onkyo 535 with this Denon. It was a significant upgrade. There is zero noise, the Bluetooth is easy to use and provides excellent sound, and the HDMI circuitry is outstanding. The eARC capability is compatible with 2.1 HDMI, and it works seamlessly. Of note, I really like the way it provides the best sound configuration automatically for each source, and I don't have to switch around to find the best sound option. For example, if the source is compatible with Atmos, it provides Atmos. If it's only compatible with Dolby surround, it switches to that. Finally, the distribution of sound is superb. I have a 7.1 speaker configuration of mostly mid-level speakers, and the Denon uses them to their fullest. Rear sounds come clearly from the rear...same with each side, etc. And most of all, I don't have to tweak the system to get that. I just used the provided microphone and ran the set up (which was really easy), and I have really great sound. This unit is a good value. ... show more

First unit was defective, second worked perfectly.
Style: AVR-X3800H
I had been excited for weeks anticipating upgrading to this receiver from Denon’s AVR-S570BT, but it was dysfunctional on arrival, repeatedly entering protection mode after operating for a few minutes and thereby being completely unusable. UPDATE: I decided to take a chance, purchasing a second unit after returning the first defective unit, and it works perfectly without issue so far. I’ve updated my rating accordingly, and am relatively forgiving of what may have been a matter of an issue slipping past quality control because I was refunded for my first purchase in full. I will update this review should my sentiment change. ... show more

Feature Rich. Future Proof. But Pricey.
Style: AVR-X3800H
For a number of reasons, I decided I needed a new AV Receiver. My primary motivation was to move from 5.1 to 7.1 and up. I wanted something that already had the established standards and would be 8k ready. To get all of that , I read the reviews and it came down to Denon or Onkyo (yes I know there are even pricier and more esoteric products). This one had ample 8k HDMI (2.1 connections), several optical / coax digital inputs, phono input, sub outs, on screen display, and speaker calibration (Audyssey mic included). It has discrete line level inputs but no composite video. Yes, it includes all the variations for Dolby (Vision, Atmos, etc), DTS (X, etc), DIRAC compatible, compatible audio streaming services, etc. Check out the specs at one of the online services. The setup was a breeze with TV/onscreen prompts for general setup as well a room / speaker tuning. The remote is ok, sleak and well laid out. I ran the tuning setup for my 5.1 and will add 2 more speakers and rerun in the next week I think the calibration process is easy enough, but be sure to follow the prompts on screen about where and how far away to place the testing/calibration mic. It does have a manual calibration/tuning process, so if you know what you want already, just jump to that menu section. I'll note that I had this in my cart for a week trying to decide to buy, and then 2 days before Amazon's big sale event it went on sale ($200 off), but on the event day (July 10-11) it went back up! Kinda disappointed in that. Luckily, I got it when it first went on sale. Bottom Line: Do you research - be sure if you really need all the bells and whistles and the associated price, and if you want to jump ahead a bit and get the current cutting edge standards. These things seem to change every few years. One thing to note, the unit does have an "eco" mode (not sure how that works exactly) but it runs Warm and produces a fair amount of heat overall. ... show more

I hope you have better luck than I did
Style: AVR-X3800H
I bought this receiver a couple months ago and finally got around to hooking it up to my new Polk speakers (Denon and Polk are both owned by Samsung) and it sounded fairly decent; not very much power but I guess the Polk R700 speakers I bought demand a lot of power. The receiver is in my bedroom and last night I put on a CD when I went to bed ~ 9 PM and fell asleep listening to music. At 1:30 in the morning all of a sudden it sounded like gunfire and cannons going off (my subwoofer just about shook the house down) so I ran over and turned off the receiver and went back to bed. A couple minutes later the receiver turned itself back on! and started the gunfire and cannon fire noises again - about every 3 seconds. The receiver wouldn't turn off so I finally ended up unplugging it. This morning I thought I'd try it again and today it won't even turn on - I've probably had this receiver on no more than ten hours - I head somewhere that Denon was a quality brand but their QA is obviously very poor. ... show more

Fantastic theater receiver
Style: AVR-X3800H
There are lots of reviews out there discussing all the capability built into this receiver, so I won't repeat all that. I'll just say that I really like this thing. We just finished building our new, dedicated home theater, and I needed a decent 7.2.2 receiver to power 11 Klipsch speakers and route video to our Epson LS12000 projector. I've had a Denon receiver for years up in our family room, and it has been flawless. This Denon fit the bill and is less glitchy and more affordable than many other receivers out there, so we purchased one here on Amazon and haven't looked back. The theater has only been running for about two months, but the Denon is performing great, as expected. Set up was easy for our 7.2.2 speaker arrangement, the sound is crisp with more decibels than we'll ever need, and video switching has been flawless. The Android app for playing music on demand via phone command when tinkering elsewhere in the house is a handy feature. I'll update this review if anything changes, but at this point we could not be happier with this receiver. Highly recommended. ... show more

X3800H a Good Receiver, but Fraught with Little Issues
Style: AVR-X3800H
This is my second Denon receiver. I have found both to be good, but the X3800H seems to have a lot of little issues that Tech Support can't seem to resolve. I've solved some on my own, after hkurs upon hours, then some of the issues mysteriously reappear. Specifically, after the first setup, Audyssey won't recognize the mic, even when changing from TV Audio to some other input. The same thing occurs when trying to get Audyssey to display on the TV. Getting Zone 2 to play tv audio took many, many hours of playing around. Different Tech Support people offered a multitude of solutiions, but none worked. The setup gets complicated when there are 9 channels on Main and 2 on Zone 2, even with an external amp. The Denon manual has a few hundred pages if text, but it doesn't go into enough detail on many things. The go-to solution from each Tech is to do a factory reset. After an hour or two, the problems still aren't solved and I pick up the next day with a different tech who starts with a factory reset. Another issue involved the AVR muting the tv on startup. A factory reset did solve that problem. I have resolved most, but not all issues on my own. The receiver needs a well-tested firmware update. ... show more

Awesome
Style: AVR-X3800H
The Denon AVR-X3800H 9.4-Ch Receiver isn’t just a gadget—it’s a ticket to audio nirvana. This beast has nine channels and four subwoofer outputs, so once you turn it on, you’ll swear you’re in a theater (or inside a spaceship). You might want to warn the neighbors, though; they’ll think you’ve set up a live concert or are hosting a sound effects rehearsal for the next Marvel movie. Let’s start with setup. Denon’s on-screen assistant guides you through, but don’t let that fool you; getting this masterpiece ready is like assembling a mini space station. Once you’re all hooked up, though, the real magic happens. Dolby Atmos, DTS:X, and Auro-3D turn every sound into an experience—rain doesn’t just “fall”; it pours around you, explosions actually vibrate the couch, and whispers feel like they’re coming from right behind you (slightly spooky but so worth it). Then there’s the 8K compatibility. Do you have an 8K TV yet? Probably not, but when you do, Denon’s got you covered. This receiver is so ahead of the game it might as well come with a crystal ball. And when paired with a compatible screen, it’s like watching reality, but somehow better. You might even find yourself watching documentaries on lawn care just to admire the crispy visuals. The HEOS multi-room streaming is a game-changer too. You can flood the entire house with sound, making every room a different “audio zone.” Cooking in the kitchen? Cue up some jazz. Lounging in the living room? Time for movie soundtracks. Suddenly, you’re the DJ of your own personal audio festival. And let’s talk power—105 watts per channel. Translation? Your house just became the neighborhood’s unofficial rock concert venue. Crank this thing up, and it’s so powerful your plants might actually start vibrating to the beat. Pets? They’ll look at you like, “Really? Another round of ‘Bohemian Rhapsody’?” For gamers, it’s a dream. With VRR and ALLM, even lag is a thing of the past. You’ll hear enemies sneaking up behind you before they even think about it. In short, the Denon AVR-X3800H is an audio powerhouse with more features than your average rocket ship. So, brace yourself for immersive sound, prepare your playlists, and get ready to turn your living room into an epic audio adventure. ... show more

Great receiver, awful volume remote control
Style: AVR-X3800H
I needed a receiver that could do 4K video switching to a projector, power a set of 5.1 speakers, and do basic room correction. This receiver ticked all the boxes. It sounds great in operation, connected to a streaming box or game console over HDMI. Movies sound great with the volume at about 60, the YouTube app is extra loud and sounds fine at about 35. I don't connect it to the internet (except when needed for a room correction run) or use any particularly advanced features. Some reviews say it runs warm, and it probably does, but I have it in open air so it gets plenty of ventilation. Denon's one fatal flaw is the volume control. There are threads on the internet about this problem with Denon receivers going back 10 years. Tapping a button slowly moves the volume by a half-step (0.5 in their numbering), which is inaudible. But if you tap too quickly or hold the button down, unlike other receivers, the volume *surges* by unreasonable amounts, quickly gaining or losing 10-30 points of volume at random. Trying to change the volume by 5-10 points is a wild battle of whiplash from screaming loud to whisper soft while you try to dial it in. I would never choose to go above about 65 on my setup, and this bug has jumped me up to 80 before. It feels uncontrollable at times. I don't understand why the rate of change isn't throttled and predictable, with one tap moving one (1.0) step, no matter how quickly you press. Every other brand I've used has figured this out. And sometimes, if you switch from pressing volume up to volume down too quickly, the volume down button will make it keep increasing in volume! I've seen this happen on knobs with worn-out potentiometers/encoders, but never with a remote. Expect to struggle with it. It's easily the worst remote volume control I've ever used on any audio device in decades. I've only used the physical volume knob a couple of times (which is on the wrong side), but I think it had the same reversal problem. ... show more
