I got this to replace a Sony head unit that was starting to fail after 10 or so years of use. This one doesn’t have the same power output, but I use Bose speakers. Bose is fairly low wattage for the most part so no problem there. Setup was fine. My only complaint is that center channel only dialog is too quiet. I need to adjust that. Everything else is great. I don’t care about Internet connectivity, but it has that if you want it. I’m very happy so far with this unit.

Nice AVR

Style: AVR-X1800H

Refurbished and looking like brand new. One small scratch on the side. It went in a cabinet and it's hidden. All paperwork seemed to be there. If I didn't know it looks like factory sealed . I've got an older Denon. Just wanted to move up to 7.2. Audyssey recognize a second sub. But neither did my older on. No problem with that though. Just FYI. After the original setup and minor tweaking it sounds fantastic for me. I haven't had it but a few days and I hope I get many years of enjoyment from this
