“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.”— IntrovertMoTown1 on Reddit
“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.”— EricST on AVS Forum
“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.”— Happy Joe on Audioholics Home Theater Forums
“it shows audio format "unknown" and no input channels. With bluetooth it detects PCM but again no input channels and there's no sound.”— ranchleather on Reddit
“I've had two Denon's die on me and literally no other brand. So I would absolutely not buy that one.”— Last_Computer9356 on Reddit
“for "normal" sound like 30%, it's okay but for "heavy" sound, like 70%+ it will heat too much”— soujyu51 on Reddit
“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.”— GKROOK on Audioholics Home Theater Forums
“I've just had to send back a X3800H because it fried it's self after about 50 hours use”— Ok-Bullfrog5059 on Reddit
“It does run hot. You will need some sort of ventilation or cooling solution up top.”— No-Horse987 on Reddit
“I went 3800 to 4800 and to me the 4800 sounds much better especially with music”— wez1968 on AVS Forum
“My 3800 is coming back from repair. I believe my kef r6 meta made it tap out.”— exfex21 on Reddit
“Worth noting, this is my second X3800H. The first one i bought on ebay and i had similar problems with PS5/Shield/Nintendo Switch etc and i guess you could call it handshake issues. Sometimes i would try to turn on the PS5 and the screen would just go black and couldnt get any picture.”— AParsh on Audioholics Home Theater Forums
Not complaints — practical notes from owners that didn't affect the score.
“I have now a x3800h and upmixing is absolutely unnecessary. Setting the AVR in auto mode is enough.”— International-Oil377 on Reddit
“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!”— Tactical on RedFlagDeals Forums
“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...”— Happy Joe on Audioholics Home Theater Forums
“Denon is a good brand, you just got a seemingly bad one.”— Sportiness6 on Reddit
“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.”— BOER on AVS Forum
“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.”— cmchiu on RedFlagDeals Forums
“it gets warm between the Denon and the shelf”— halu2975 on Reddit
“Not until last week with my 3800 at least”— weight_matrix on Reddit
