I've been trying some headphones with the space setting on 6 and it sounds decent. This might be somewhat of a solution. These headphones are regular Sony $30 at best buy, so I'm assuming getting a $120 pair like the ATX-50, or HD280's might sound even better.
Just bear in mind that the m50s are more bassy while the m40s are "tuned more flat". That's why I went with the 40s, not because of the small price difference.
