There should also be a different _phase_ response, and that is not shown from the simple sweep of amplitude response. It makes sense to me that this could affect positioning and realism, even if a tonal change is not detectable. But I'm still not sure why it should be better with either curve in particular. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=76763 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
