Having the sides slightly back helps for 5.1 content. But if you always use something like Prologic IIx, or NEO:6 having them closer to in a line with the ears does make noticing surround effects easier. Human ears work best from the front to the sides, their ability to discern directionality falls off as sounds move behind the head.
