My Denon ROCKS
Style: AVR-X3800H
Pros: Nine Amps power a 9.1 or 7.1.2 or 5.2.4 speaker configuration because most of us want Atmos to work in our listening room. Plenty of power available in each amp and each configuration Atmos DTS IMAX plus any other codec or audio visual enhancement is available. Yes, 4K 8K HDR all supported. Three HDMI outputs Preamp output for up to 11 channels so any combination of preamp vs. power amplifier output is available. But not both preamp AND power amp for the same channel. And you can pick and choose which channel you want for pre amp vs power amp individually. So it can function as a AV Preamp Processor at very reasonable price point. DAC (changes Digital Signal to Analog) with all the power amplifiers you could want. High quality, including DSD, is an added bonus. Setup customizable to the nth degree. Some people might say too many options but that’s the way we get this AVR to meet our individual requirements I’ve been working with the setup for the last week and have dialed in for my needs. Still playing with the HEOS but I think it’s working well for now. Various HDMI inputs need different surround settings, I like the DTS best, but the unit has a way to include default settings for each HDMI. I’ll use default settings with my BluRay. And I’ll use direct or pure or whatever the source allows for music and streaming. And most users will want a streaming stick like the Amazon one otherwise you can’t get the Atmos signal to work. Older streamers won’t pass the Atmos signal though. The only problem with a device like this is you will buy more speakers and amps and possibly even more subwoofers, the unit will support 4 subwoofers. Enjoy So I will get back to you with comments about longer term issues. BTW the 3800 was a refurbished version for $999 . Definitely an excellent value. The online reviews are quite favorable. Even the audiophiles are still learning the nuances of setup. It’s worth the extra effort to get the most out of each user’s individual existing equipment. Cons: None. I’ve been an audio video nerd for decades so I can say that the setup effort is easily justified once the user, with user manual in hand, patiently works out the desired configuration. The audio expert online information is invaluable. I have 21MBS broadband service in my region. Even with this limitation I have more than enough added capacity with the Denon that I would never return it to seller unless someone catastrophic happened. Yes I like it that much.

Denon Refurb AVR-X3800h.. IMPRESSIVE!
Style: AVR-X3800H, Style: AVR-X3800H
I did a lot of homework and made contact with the seller. Great communication. Turns out all of the Denon refurbished receivers are inspected or repaired by DENON, and re-certified only after passing tests upon functional as new. It arrived in a Denon box, very well insulated. Contained all NEW accessories like new & sealed. Appears flawless. The setup was easy since I have years of previous experience with surround systems. This replaced my Onkyo of 10 years. And WOW, the difference is phenomenal! Great onscreen setup + smart phone app makes it nice for making fine tuning adjustments. This model is packed with all the latest tech. The Durac Live is easily downloadable, but I am so impressed with the Audacy setup I didn’t buy the download. Great value refurbished. It comes with a one year warranty, so I purchased the 3 year assurion warranty since I saved so much money. Very happy.
