ok this is VERY simple. there is no such data that i am aware of and I would be happy to be proved wrong about that.
thus, all we have to go on is subjective experiencs at the moment.
I realize this is very uncomfortable for those who are completely left-brained but since there are no dbts on analog stages of blu ray players yet we have nothing to go on but subjective comparisons.
Now some of us may think this data is meaningless and thats fine.
some of us may think this data has some value in that it is better than nothing and that is fine.
and some of us like arguing for the sake of arguing in anonymous internet forums.
