Thank you, slfan, for addressing the Mikros 90 vs. B&W P5/7 differences, for your very informative and helpful observations! Poor placement and/or obtrusive outside noise would tend to diminish or nullify all that fine Mikros 90 detail at either end of the frequency spectrum.
I think it is very difficult for a single set of headphones to faithfully deliver elevated midbass pressure without simultaneously eclipsing deep bass detail, especially when deep bass suffers steeper dB loss. The D7000, as I recall, were able to pull off this feat to an appreciable degree, but they were somewhat bass-forward and not quite as clean way down deep as the Mikros 90.
