Really there is no answer to which is better or brighter if that was the case. Your room, your gear, your cables, all work together to make the sound you hear at home. I've heard my M3's sound bright to balanced and then to the warmer side of things, how? by switching power cords around. Nothing else was changed, just flipping powers cords from one unit to another, each power cord different, AQ Huirrcane-3, Firebird, and then a Dragon. Audio is like cooking, the food your like is the spice you add to it, to your taste. Get your room right, then work on setup and toe-in, and depending on the room and its size toe-in will highly vary.
