I love dynaudio, but depending on the setup, they may not be the right speaker for an office system. They don't perform well in the nearfield, they are made to have lots of breathing room.
If your office is large, and you'll be sitting 7-8+ feet away from the speakers, then either of the Dyns you mention will sound great
