I am looking to buy a new 1.4A 3D AV receiver in the range $600-800 price range. I have looked at some of Onkyo’s, Integra 50.2 & 70.2, and Yamaha receivers. I could use some recommendations on what would be the best buy. Don’t necessarily need 3 zone, and more than 7.2. I have a huge room and I am upgrading my entire entertainment system with control4 automation, and other AV components. I am running a Def Tech Mythos 5.1 system. Please help.
