“I just bought a Denon X3800H AVR. The video upscaling is really great on this unit.”

80% of 98 verified owners recommend the Denon AVR-X3800H, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.
Affiliate blogs here say 100% recommend, while the owner-based score is 80%. They earn a commission on every sale — so we show them for transparency but never let them move the score.
The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube and Affiliate blogs are shown for perspective but kept out here — hover the i for why.

“I just bought a Denon X3800H AVR. The video upscaling is really great on this unit.”
“I have a Denon x3800h it's not the greatest AVR but not the worst either. I quite like it for home theater and multi channel audio/Dolby mixes.”
“my Denon X3800H did. I mean hot as in relative. It's not like it burns. But it was definitely hotter than what I'd like electronics to be at.”
“Love my X3800H.”
“Replaced the cinema 70 with a denon x3800h. Much better room correction (obviously) , but even missing warm and stereo image of old Kenwood.”
“One issue the 3800 has that drives me crazy is when watching Directv stream through Apple TV it clicks loud when the audio formats changes like from show to commercial.”
“I have the x3800h and wasn't satisfied with stereo reproduction, so I added a Naim Nap150 power amp”
“Love my Denon X3800H! Got it for $999 last month!”
“This firmly establishes, in my mind, that the X3800 is simply not up to the task of powering 5 speaker (down from 7) surround sound when the speakers consist of the polk R700s in front and Klipsh R26F A's as rears.”
“it shows audio format "unknown" and no input channels. With bluetooth it detects PCM but again no input channels and there's no sound.”
“I’m very satisfied with the x3800H after I off loaded the front end to a separate amp.”
“I run a 7.1.2 setup with a X3800H. I am very happy with it.”
“i have a x3800h and i’ve never been happier, its so organized and has no issues whatsoever.”
“I've had two Denon's die on me and literally no other brand. So I would absolutely not buy that one.”
“For the most part, I am very happy with the receiver.”
“I have the RZ50 and the X3800H and love both of them for movies and music !!”
“for "normal" sound like 30%, it's okay but for "heavy" sound, like 70%+ it will heat too much”
“Sometimes when we are watching a movie or streaming content or listening to music the X3800 shuts down. The receiver is sitting on the top of my equipment stand and and gets plenty of ventilation. When this happens I touch the X3800 and it is slightly warm or cool.”
“X3800h was a hassle free replacement for my old denon 3311ci. I needed 4k. After running room adaptation I can hear voices much better on the x3800h. The setup was super easy and fast.”
“I'm quite happy with the receiver.”
“I've just had to send back a X3800H because it fried it's self after about 50 hours use”
“for me It sounds worlds better for music than my previous AVRs, the last couple of which were Yamahas. They had bulletproof reliability as you mention but sounded flat and lifeless in comparison.”
“It does run hot. You will need some sort of ventilation or cooling solution up top.”
“I went 3800 to 4800 and to me the 4800 sounds much better especially with music”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“I have now a x3800h and upmixing is absolutely unnecessary. Setting the AVR in auto mode is enough.”
“Just arrived today. Really excited to hook this up to my Klipsch Dolby Atmos 5.1.4 from deep clearance at Costco and testing on PS5 now that it supports Atmos!”
“I too have had shutdown issues with a Dennon x3800h; It occurred to me, last night, that since I was trying to use it to power an 11 speaker surround system (using 2 power hungry Polk r700s, in front) that I might be abusing the power supply excessively...”
“Denon is a good brand, you just got a seemingly bad one.”
“I had problems with my Denon X3800H when I first got it (coming from a Denon x1500H). The impact and bass sounded crap, and I configured things through REW afterwards. It turns out my calibration mic was semi-faulty - I recently swapped it for a new one and all the impact and bass is back, and sounds great.”
“I have it on Ethernet (wired) and haven't had any issue. I've received firmware updates (eg. Dirac capability). The only issue I've with this Denon is with its BT connection to my Bose noise-cancelling earbuds. Either turning off BT transmission and on again, or unplugging power from Denon for 5 seconds fixes it.”
“it gets warm between the Denon and the shelf”
“Not until last week with my 3800 at least”
“lol I may well roll the dice again.”
