Put a pair of Quads or Maggies next to a big pair of wilsons or Dynaudios. Play some dynamic rock or jazz music. You will near night-and-day differences in dynamic capabilities between the planars and the boxes. Granted, you'll also hear night-and-day differences in transparency in favor of the planars... so pick your poison.
