I have a Denon AVR-1905. It's what I use for all my audio-visual things. It's seen constant daily use since... welll, whenever I bought it all those years ago, in the year 2000something.

I have a 5.1 setup of Paradigm speakers hooked up to it. No DVD player or CD player or anything else, but I play music through my PC, all my games sound, all my digital movies go through it. My PC is my TV. It's basically a giant media-center the way I use it.

It does 5.1, Dolby and/or DTS, and that's good enough. Hooked up through an optical cable so it sounds great. Super simple.
