^Wowza. That's a steep smile you got there.
I can't see you finding that sort of balance naturally coming from any system! If that's the sort of balance you like, then you'll need to keep EQ'ing your sound. If your hearing is OK, then you may have habituated your hearing into preferring that balance. A typical example of what I'm talking about is that when I listen to a Grado and go back to my HD650, the latter sound dark until my ears re-acclimatize. It's similar to claiming a room to be dark after coming out from bright sunlight. However, on remaining in the room, you're fine. It's never as bright as outside, but it's never fatiguing either and the lighting is enough. OTOH, if you have a visual problem then you'll likely need good lighting to compensate and will be more comfortable with a brighter ambiance than others may like.
OTOH, on seeing how the mids are suppressed, I'd think this has nothing to do with hearing issues, but just habituation.
