Value for your money
Style: AVR-X2800H
I am loving the sound quality while listening to music as well as watching movies. I am running a 5.2.2 surround sound which is a step up from my sound bar and I am loving it. This receive has tons of features. Apart from the sound quality, I love the fact that I can set my power on volume and a volume limit.

More like a 7.1.2 not 7.2
Style: AVR-X2800H
Looks and feel brand new, set up is easy especially if you have used Denon before. I needed to upgrade my old system to get the 8k signal for a new TV i bought.
The only issue I've had is its listed as 7.2, but its more of 7.1.2. You can connect 7 speakers and adjust each individually, you can connect 2 subs but they both receive a split signal and can not be individually adjusted in the receiver.
A little misleading, but still a great system.

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.
