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.
