I think you'll find that the picture quality of changers isn't what a single disk player is. I have no idea why, other than pure speculation that folks looking for a changer are more interested in CD playback than watching DVDs. So the manufacturers consider this, and don’t put as much R&D into changer PQ.
My integra changer is about at the bottom of the list on the last DVD ranking sheet I saw. I could have bought about any of your listed Denons for what I paid for the integra. My old Toshiba 6200 has better PQ than it does. But it does have amazing CD playback, so I’m not too bummed about the deal.
So I’d suggest that you list your priority – changer or picture quality. Then the experts here can give you input on what they think the pros/cons are.
