Mike,
I have tried demo'd both in my system. Current gear: Luxman D-08 digital source, Luxman Pre/Power, Richard Gray power conditioner, Vivid B-1's. In my room and with my gear the LS-700 is more refined with top to bottom coherence that is lovely; generally sweeter sounding to me. Both very good but LS-700 better IMHO. Don't know if this will help in any way but my two cents.
