I'm curious, DrunkenWolf, how would you characterize the difference? And John, I understand your logic, but to extend it a little, why even then purchase a mid-level Yamaha, Denon, Pioneer, etc? Why not go with one of their lower cost models, which seem to have the same bells and whistles and similar power ratings? Should one assume there are certain elements of 'build quality', below which undesireable sonic character is noticeable? In a nutshell, "How cheap can one go?" And again, thanks to everybody - this is great info!
