I, too, was debating between the Marantz AV8003 or there newer AV7005 as well as the Integra DHC 40.2. In the end I ended up with the Marantz AV8003...awesome picture and sound quality. I was told by the Marantz tech guy that the AV7005 was introduced more for the entry HT type person (it is 3D capable with HDMI 1.4) and that the AV8003 is a much much better component for both video and sound.
