I own both a Onkyo 805 and a Denon 3808ci and although I love both, I would say that the sound quality is a hair better on the Onkyo. I should mention that the Denon has AR Phantom 8.2 speakers all the way around, while the Onkyo has DefTech BP 7001sc's, a DT 2002 and Mythos gems as rears. (both are 7.1 setups) I would go with the 875 or go with the 2808ci and a nice 5 channel amp for under 2,000
