I received mine today from Amazon. It arrived in 4 days, in perfect shape. I have my DirecTV HD, Blu-Ray and Xbox all connected to the 709 via HDMI, and then an HDMI to my Samsung 60" 6042. I updated the firmware the second it was out of the box, and have since been playing with it all day. I run a 5.1 set up with 5 NHT SuperZero 2.0s and a Cadence CSX-12 sub. I have been cramming the manual well before I received it, so everything has been pretty uneventful.
I ran Audyssey, and set the sound fields to THX Cinema.....Wow! It sounds incredible. Night and day difference between this and my Yamaha RX-V471. We will use the crap out of the 709, as it will be on 100% of the time when we watch TV, DVD, Blu-Ray and Xbox.......... I do have a couple of Audyssey questions, but it's late, and I'm fried!
