Acoustat-X, was definitely my first WOW speaker...
for about 25 years after purchasing them, i heard a lot of great speakers and headphones.
Mostly other electrostats, ribbons, and planars...best Stax phones, etc.......that all sounded great, but all seemed to present a mainly lateral move...not really any new WOW.
Also auditioned a number of highly regarded conventional speakers, looking for more bass, SPL, and dynamics than electrostats/similar offered.
They just couldn't convince though.
One day, feeling a bit bass starved, decided to try some prosound boxes.
Meyer-UPA-1p's with a 650-P sub. Bought them unheard, based on the large list of finer theatres and live-music halls they were installed in.
Totally loved them the moment I set them up in my room..
But the wow was still to come...
Set them up outside for a party...and my second major WOW was heard.
I expected bass, SPL, and dynamics.......but I had never heard such clarity and definition from any speaker before...period.
(outdoor listening with high quality speakers strong enough to pull it off, is something to behold imho..)
Anyway, since then, I have developed a DIY hobby of building speakers robust enough for outdoor use, knowing that they will provide extraordinarily clean indoor use.
My current LCR setup using three identical synergy horns, each on top its own double 18" sub....is definitely WOW the third.
Over and over again, past a half year's use now all indoors....i keep saying WOW....makes me laugh how good it can sound... (had a few folks tear up
Now I just gotta figure out a way to take this whole LCR setup outside lol
