Very nice review. I heard the LTA/Spatial Audio combination at CAF and liked them very much. I then heard them in a subsequent setting and was disappointed. Can't really explain it. I am thinking of giving some open back woofers a try with my Magnepans. Don't think Spatial makes a separate woofer though.
