The only speakers I have heard on your list are the Totem Wind and the Olympica III. I like the Olympica a good bit better. The demos were too far apart for me to give detailed comments but I feel the nova is as good as anything in its price range.
I would add the Wilson Sabrina to the list. Similar sound but a bit more leading edge in the bass.
