Everything arrived yesterday; Onkyo,amp,4 new speakers and mounts. It took me 6 hours to run wires,mount speakers, hook up ,test everything and cleanup! I finished at midnight. I havent done Audessy yet, only volume calibration, but the improvement in sound quality is glaringly obvious. I'll probably do the Audessy tonight after work. At 10pm last night I was really wondering if it was worth all the effort, but when I heard it the first time I knew that it was.
I do have one question:
This is the first unit I've had that will scale video from HDMI connections and I'm not sure what the best settings are. For instance for those of you with Directtv or Comcast HD DVRs, what are your settings for DVR and 5507 ?
