Eldartford,
I think that you are thinking along the same lines as I do in terms of the perception of the sweet spot, and I hasten to add that the sweet spot also contributes immensely to the dimentionality of the perceived sound. You certainly can discern the soloist in the middle but also the attendant musical instruments that provide the beat and rhythm of the music. Because of this dimentionality the depth and width of the soundstage is also perceived. The presence of a center speaker only serve to stabilize the central location of vocals and dialogues because it is really meant to synchronize with the image on a screen. From a musical only perspective I am convinced that 2 channel sound is superior to any multi channel sound because of the central phantom image that it delivers. Multi channel sound delivers plenty of great sounds but sadly with minimal cohesion. It tends to be a slam_bam_thank_you_mam presentation.
