Worth the Money
Style: AVR-X2800H
I have had this item for a few weeks now. This is the first high-tech AVR I have purchased. I decided to retire my 25 year old Denon AVR 900. Still works awesome and is in perfect shape. Needed to upgrade to newer technology. Many will frown at this, but I initially sent back an Onkyo TX-RZ30. I just found that I did not feel comfortable with the technology, but it is an exceptional receiver. I decided to go with the Denon AVR-X2800H. I just feel more confident with the Denon layout and setup guide. I have not been dissapointed. I very reluctantly ordered a refurshed model. I can tell no different, even in the packaging. Looked totally brand new. I will say that I am still learning all of the setup, but so as for ease of general setup and assigning speakers it has been very user friendly. I was curious to see the sound difference with music between my 25 year old Denon and the new Denon 2800. I was not dissapointed. I have a smaller room for the AVR, so I am using Klipsch 600II, Klipsch 400C center speaker, Fluance Signature Series bookshelf speakers, and Polk OWM3 rear speakers. The receiver push all these speaker quite easily and efficiently. I would definatly recommend this Denon model. Can it last 25 years plus like my other Denon. Only time will tell.

Please Read for Troubleshooting Info
Style: AVR-X2800H
I purchased a refurbished device and at first it worked fine. Then it started having a lot of trouble on power up locking into my DirectTV cable signal. It kept powering up my Blu-ray player and accessing its menu, even though I had not selected it and there was no disc loaded. I became frustrated enough that I returned the device. Wish I hadn't as it was a nice home theater system. To make a long story short, I bought another brand of receiver (for more money) and continued to have the exact same problem. Finally, a Google search found a troubleshooting solution on reddit. Many reddit users suggested turning off the HDMI CEC control. This was easier said than done, as this HDMI CEC control setting was not found in the Denon receiver menus. It was found in the setup menu for the Blu-ray player. Once I found the proper setting and turned it off the receiver was no longer confused and trying to access the Blu-ray player upon power up. It locked in on the DirertTV signal and was rock solid. I wish I had learned this solution earlier and had kept this nice receiver. I'm so bummed.

Good receiver.
Style: AVR-X2800H
Very powerful and good quality receiver for the price. Replacing my Yamaha after it got burned out. Pulling my BW speakers with no problem at all. Very pleased with the performance.

"factory certified" broken receiver
Style: AVR-X2800H
So I call b.s. on these. Here's why. I got a unit with a broken IR receiver. I cannot imagine a real factory certification process that doesn't involve making sure the unit responds to a remote control. This one of the first things you would try to make sure something works.

Great upgrade to my Denon AVR-X2400H
Style: AVR-X2800H
Good audio and video quality - a great upgrade to my lightning-zapped AVR-X2400H.
Audio analyzer works better than the earlier version, but still required some tweaking of the rear surround (reduce) and Front Center (increase) channels.
I had to raise the input trim levels for my HDMI 1&2 for TiVo and Roku to get the output level active in the first 1/3 of the volume control range.
Bluetooth feed to external headphones works well but does not have the same volume level range as the main audio. Audio quality is not quite as good as the main output but will be good for late night listening.
1080p menu system is a nice upgrade. Some complain that it is not 4k, but who needs it?
My old remote works well (since it is the same model). Responds quickly to commands. Quick menu is nice and works well.
Sirius XM works thru the required HEOS app on my phone. Some other streams work natively. I have not been able to connect to my Windows Home Server for my music library yet.
Included all OEM accessories and a link to the manual, which is linked in the system menu. Other than a few finger smudges on the face, it looks good.
As a refurb, I bought the extended warranty just in case.
