I agree that you won't get any worthwhile improvement in clarity/detail. The Vandy tweeter is a bit sibilant compared to the Spatial's compression driver IME. Where the Vandys excel, and panels/open baffles are lacking, is in pinpoint imaging.
The Spatials also play much louder than Vandys before compression kicks in. You're really going to have a hard time beating the Spatials at that price point. You might look into their new X5 speaker.
