Spatial Audio open baffle speakers, who has them? Worthwhile change from Maggies?


Of late have been eying the Spatial Audio line of open baffle speakers and like what I have seen and read so far.
Now I am extremely happy with my baby Maggies which have easily bested any and all box speakers in my room ( that I can afford anyways!).
So looking for opinions and views from actual owners of said open baffle speakers, what did you change from and what are the real strengths of the Spatials?
Not short of horsepower to feed them even though they do not need much juice by all accounts but you know the old saying, " too much is never enough!"
Thanks in advance.

I agree on the townshend supertweeters.  I have them coupled to my Martin Logan montis.  However, I found they are best when I have them next to the Montis on their own speaker stand and pointed backward toward the wall behind the Montis.  Incredible increase in airiness and widened, deeper soundstage.
Part 4 in Danny Richie's series of videos dedicated to open baffle loudspeaker and subwoofer design is now available for viewing on YouTube. The best one yet! A GR Research YouTube search will bring it up.
