Summary: The 7.1 sound field is breath-taking, giving new meaning to "home theatre". Tuning each speaker to the size and accoutics of the room is a major deal-maker. I have both blue-ray and 3D TV in the system and the RX-Z7 makes movie-going obsolete. I use HDMI connections for all video inputs. This receiver had my set up in mind. I also use a optical digital connection for the CD player.
