I know that with your settings the sounstage is bigger. You get a better surround feeling but I can hear distortions and with your high quality headphones I wonder that you don't hear them.
But if don't hear them your settings are good for you. Without this distortions I would prefer your settings too.
My settings are a compromise between getting surround and not altering the original stereo image to much and could also be used on a real 5.1 system.
