Dan001, you haven't mentioned a dealer yet. Did you buy the DALIs off A'gon or a dealer? If a dealer, then what amp was he using when you auditioned them? It might have been a smaller room than yours, but it would be a good starting point.
I really doubt that the Bel Canto will do any more for you.
One other thing, how far out are they into the room? They actually like to be relatively close to the rear wall, but away from the corners. You may find them best only one or two feet away from the back wall. You'll run into bass modes there, but if move them out a few inches at a time, listening to a recording with lots of bass AND a female vocal, then you can get that all in balance That close to the wall very small moves make a huge difference.
