Lets say you had a budget from $300-400. low THD is priority (THX cert if possible), 7.1 preferred but 5.1 would suffice, 3D ready is a must, minimum of 4 HDMI in.
I'm happy with the 607 but would really like 3D capability. I don't want a downgrade in sound quality compared to my 607 just to get the 3D capability though.
the nr616 is tempting but the documented issues turn me off.
