Denon AVR-X4800H 125W 9.4-Channel 8K Network AV Receiver

So far this is a great receiver. I enjoy the extra watts and mostly the smaller size to fit on my console. Hopefully, it will work for many years.

Denon 4800 is very good, I upgraded from 2700h, looked around other brands similar product but settled on denon again.

There are two denons. Tech support is incredible. They are easily available, helpful, knowledgeable, and patient. They are why I bought this denon. Sales support is the opposite. I could not be available on the date that denon unilaterally scheduled delivery - and I had to sign for delivery. I asked sales to change the delivery date, which would have taken a 5 minute call to fedex (fedex required the sender to permit a date change) and sales refused. So I had to arrange/pay someone to be available to sign for it. Disappointing for such a highly rated brand.

I was looking to upgrade a 23years old Denon AVR-5803 receiver. Newer technology and connectivity were crucial requirements. I waffled heavily on this AVR-x4800H, with only 125w/channel, vs my 5803 with 170w/channel. Denon had a remarkable sale on the 4800 vs the 6800 (which was about $1. 5k+ more). Only differences were watts and a few additional inputs. So I bought the AVR-x4800h. WOW, this weights half as much as my old Denon, but man does this unit deliver sound. Entire speaker system is Klipsch branded reference series. The system came with a microphone for calibration with a built in program that was easy enough for a "caveman" to use (sorry Geico!). Customer service at Denon has been fantastic before and tech support afterwards. If you have out of date components and are thinking of an update, DO NOT hesitate on looking at this new lineup! Your ears will thank you?.

I havent fully gone through it yet but have been through set up with Audyssey. I couldnt get it to recognize surround rear speakers as I have just 5. 2 at the moment, it kept assigning side spkrs instead. Seems to sound okay though. I am also having issues with powering off. It will power off as it should only to turn back on after a second or two, sometime on the same format as when it was shut off but sometimes zone 2 or 3 is shown. another instance the AVR seems off but audio is playing quite loudly from the Tivo feed. I obviously have to dive a little deeper into the setup I guess but am a little concerned about the powering off and then right back on issue.

One of my favorite pieces of audio equipment. It has made such a difference in my setup. Price was fantastic, and for me it was worth the jump up from the x3800. Cannot recommend enough.

I purchased this unit as a replacement to a much older Denon receiver. I was weary of buying something refurbished, but the price was right so I took the risk. So glad that I did. I am so happy with this machine. I use it for both movies and listening to music. It does not disappoint. I don't even want to leave the house now.

This is a nice Denon. I got it refurbished for close to 50% MSRP, arrived perfectly new in appearance aside from a tiny scratch next to a screw head where it'll never be seen, as the machine was obviously opened and repaired. The 2022-lineup of X-series AVRs are good. They are versatile, and highly customizable. The Denon Remote app is a must and is great on iPad for digging into all settings very conveniently over the home network. Performance wise, this is capable and had no issues whatsoever running a large assortment of Klipsch towers from their RPII line, and an RC-64iii center for 7. 2. 2 cinematic bliss. Audyssey calibration works very well and then fine tweaks afterwards help dial in your perfect room profile. My only complaints about the AVR itself is that it is a little slow to accept changes made via remote input, the amp's relays can be annoyingly loud while switching outputs from say Atmos to DD, and that it was scratched by the repair team. For this price Dirac should also be included (see: Onkyo) as it'd be nice to freely switch between Audyssey MultiQ XT32 and Dirac Live without having to pay another three or five hundred dollars. Hopefully Denon works out a licensing in the future for us. Suggestion: while I love the classic form factor os all Denon AVRs they really need to add a decent LCD screen to allow more (or less) data to be displayed and color customizations say, all red lettering for least intrusive. Otherwise the build is very high quality.

Electronics seem OK on this refurbished unit. However, the front door panel binds in all its movement and will not shut completely. Since it's the part of the unit everybody sees, I thought Denon would replace/fix the door before selling.

I bought the latest refurbished receiver with the extra discount. It arrived as new, no visible marks or anything missing. Amazing receiver, plenty of power to drive my speakers, and setup was a breeze.

I just received my new receiver and I think it is great. I replaced a much older Denon AVR, and the difference is amazing. When I bought this thing, I knew I had to replace my speakers. To my surprise, it is a whole other world. These speakers never sounded like this. They prove a much richer sound in music, and the surround is so much better. I love this thing! My only negative comes during the setup. I am no stereo aficionado, so understanding how to set up the speaker configuration was a little difficult. I completed it, but I didn't think it was right. I had to spend some time online searching for some knowledge. I was able to get it done, but it would have been nice if it was easier to understand for a novice. Overall, I would buy it again.

I took the advantage of additional 25% discount to purchase the X4800H, a total savings of $1,000 from purchasing new. The receiver I received seems like new; sounds great playing Blu-Ray / Netflix / Apple TV. Very happy on this purchase.

First time purchasing a refurbished Denon. You'd never know it wasn't brand new, from the packaging to the performance. After enabling Dirac, my basement theater has been transformed!

1st higher end receiver I've owned and extremely happy. The main thing I've noticed is how much better my T. V's picture is, also the SVS Ultra Speakers so great with my receiver. I'd recommend to friends and family.

Best receiver I've owned yet! I've had no HDMI pass-through quirks using multiple inputs, and the sound quality is fantastic for my 7.2.2 setup (using external amps on the subs). Dirac Live makes this AVR just amazing! You'll need a MiniDSP Umik-1, a mic stand for positioning, your laptop, and a Dirac Live Full** license for the 4800. It really is able to bring everything into this cohesive sound stage that is so much better than Audyssey XT32 alone. I used Audyssey to set distances and gains, then Dirac to bring it all together. Wow, it's awesome! I highly recommend!

I've been wanting to get the 4800 for a while now. Adorama made it happen for me. Great price, fast shipping, and top rate service---they were constantly reaching out to make sure everything was right and as I expected--it was and is!????. Excellent unit!!

I shouldn't review this since mine did not work when received, but Adorama keeps sending me emails, so here goes. The receiver has all of the connectivity I wanted, short an HDMI port on the front (really, Denon?). The user interface on the TV looks pretty good, and I liked the guided setup. One thing missing from the guided setup, in my mind, is the opportunity to tell the receiver that you are bi-amping the front speakers. You have to go into the manual setup to do that. Initial boot up is slow, but I'm guessing once it's set up it's a little faster; I never got that far to know. Everything worked on my receiver except the sound. I went through troubleshooting with Denon support, and determined that the receiver was defective. Not sure if it came from the factory that way or if it happened in shipping. The box looked mostly good. I'd have waited until I got my replacement in order to do a better review, but Adorama refunded me instead of sending me a replacement.

Great unit, met my already high expectations. Adorama experience was perfect too, and at the best price. I also bought Klipsch speakers from Adorama a few years ago and had a perfect transaction then.

Excellent made in Japan receiver. Has plenty of power to drive most demanding speakers. 4 subwoofers out and fully 8K, Aura 3D, imax and more. Excellent sound fidelity even at lower volumes and vocals can adjusted.

Upgraded from a Denon 3700 that was a couple of years old. Same solid build quality with a few more frills. The sound quality was marginally better but the picture quality is way better than the 3700. The other reason for upgrading was to use the pre amps for LCR and the 4800 has the ability to use them as pre-outs. The one thing that I found was the subs were calibrated to a higher output compared to the 3700.

I have been using this device for a few months and am very satisfied. Installation and use is not complicated and the quality of the output is very impressive.

So the receiver was already a top notch upgrade, saying you have a nice set of speakers and a quality sources. But Dirac Live (Full Version) is next level, this is your reason to upgrade to the AVR-X4800H. It makes such a cohesive and balanced bubble of sound after properly* configuring Dirac (make sure to watch a few YouTube videos). Save the default results as flat, and then create a movie and music curve the way you want it to sound. Once you have it how you think* you want it, upload it to the AVR and take it for a spin. Dirac has finally freed Denon AVR's into something exceptional, not just great. JUST FYI: You'll need a MiniDSP Umik-1 (or version 2, but not necessary), the curve text file from MiniDSP (90 degree version), a microphone stand to place the mic as instructed, the full Dirac license, your laptop annnd everyone out of the room (as close to absolute silence as possible). Watch some videos on setting up Dirac 3 so that you understand the initial settings etc. After each position is completed, hold on to your hats! You may need to adjust volumes here and there afterward, but you will notice that, wow, this thing sounds WAY better than Audyssey on its very best day in a perfect world with the Apps. Denon, thank you for adding Direc Live 3, now can we have Dirac Bass Management and Dirac ART (Active Room Treatment)? Unstoppable? Thank you in advance.

I'm coming from the avr3600h. Was excited about the 4 subs option. After I got it all hooked up there was really loud buzzing from my rear Dolby speakers from the pre amp. I changed to rear surround using different set of pre amp. Still buzzing. Then used my old Denon 3600 and used the front speakers pre amps. And I made loud popping crackling sounds. Of course it the weekend so I'll try to contact customer service Monday and send it back. Very disappointing. Had high hopes. But the sound on all other channels was great. Just those preamps not working.
