Hi all, I'm looking to upgrade my Sony STR-DH520. I'm currently running 5.1 speakers. I want to upgrade the a better quality sound. I've heard some Yamahas, and they sounded great, however I can't try them with my speakers. My budget is around $400 USD. The things I want to get out of the new receiver are: 1. Second Zone (Wireless speakers, if possible). 2. Bluetooth (Airplay?) 3. At least 4 HDMI inputs. 4. Headphone jack. 5. XM Radio tuner. (Although I can do this with my phone + blue tooth). I'd like all the latest decoders as well. I want to run a 2nd zone for blue tooth, so that if someone is watching TV, I can use the 2nd zone with my phone to stream music. If I can do this via network- might be even better because the blue tooth range isn't so good.
