Quick background: I currently have AKG K81 'phones and MeE IEM 'phones. Both are similar once I EQ out canal resonance (and all that other stuff, yippee-ki-ay). I need to get a proper pair if I want to enjoy them because the AKG developed a channel imbalance (and frequency mismatch) while the IEM require drastic EQ and pop out any time I do something that causes my ears to move. I laugh or smile easily so I can't keep them in and have quit using them altogether.
My problem comes down to the virtual stage locations and depths in the soundstage with all music. Maybe some HRTF processor or otherwise could remedy these things and bring the virtual stage to a proper balance. Maybe I didn't search hard enough, but I think I can find a solution that undoes the collapsed-stage effect. Any suggestions on what can be done or links to the science behind this kind of thing would be helpful.
A song with a stage that suffers more than average when transitioning from speakers to headphones (in my case) is The Four of Us are Dying from NIN.
No comparison to the 24/96, but the collapsed-stage effect is the same.
