Good post, you're right.
I also do wonder if my LCD-2s are partially to blame. The "loss" in detail is probably only lost or dissipated in the simulated space between me and the "speakers", so I wonder if a pair of more resolving cans like Stax, might be better suited to this application?
While I agree on the losses you speak of above, there are some gains too, like extra dimension revealed by the cross-feed, or the treble dissipation that makes even bad recordings bearable, that smooth FR.
Edit: One other thing, using Isone (depending on your settings) can reduce your overall volume. I have to crank my volume more to get to the same decibel level, I'll try listening this way to see if those subtle microdetails come back to some extent. That might have had something to do with it.
