I have owned the 800 Sigs and currently own the 800d's. The 800d is a much more amazing speaker than the sigs. It could also be that the new design works better with my "cursed by the gods" room that I have, but they work for me. I am comparing these speakers using all the same equipment. I don't know if Sphere has done the same type comparison. If he listened to two different speakers in two different systems or anything else was changed when the speakers changed, could make all the difference in the world. If it were same for same, Sphere just has different tastes than I do, and/or a better room.
