I'm looking forward into getting in the HDTV arena, but I need a receiver. I have a mits 55809 TV and plan on receiving the majority of my HDTV on an over-the air antenna. I also have Direct-TV and will be using a few of their channels. I have a Yam-RX595 receiver for my sound if that matters? Any suggestion good or bad would be appreciated. Willing to spend up to $800, but quality is more important to me.
