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.
