I have a Samsung HD931 and the PQ is excellent, I don't really see any major issues with Black. I am looking to pickup a Denon 2910 since I want to go SACD/DVD-A and also the PQ is supposed to be even better... I dunno how, its already Awesome!

What is your price range? The Denon 1910 is supposed to have Macroblocking issues.... Seems like nothing is perfect.
