I'm going to be getting a new AVR as I update a home theater sound system piece by piece. I'm looking to spend about $500 on a 5.1 system. I may go 5.2. I'd like to be able to stream music over it. Stay around 100 watts a channel. I worry my speakers would be blown over that. What do you have for an AVR? What other features should I be looking for? Your advice is appreciated.
