Great review. Among so many poorly written reviews that are beeing published nowadays, this one is a stand out.
As an S5 owner, I share many of your comments. What I found most interesting, is that the S5 were not exactly awe inspiring under show conditions (Absolare excluded).
I also haven't heard the S5 sounded anywhere near good under show conditions. For whatever reason, Magico most often exhibits with Solution or Spectral gear, which I dirctly atribute to the flat, uninteresting sound. I had to borrow the speakers from the Polish distributor to find out how good they are. I ordered them on the spot after hearing them in my room (my previous speakers were Wilson Sasha 1), and didn't regret my decision any single minute of the 3 months I had to wait for my own pair.
The biggest difference between the Sasha and the S5 were the smoothnes of the midrange/HF region, and an uncanny bass articulation (that came as a surprise, as I never complained about the bass quality of my Sashas). Initially, I had a problem to recreate the soundstage depth I was getting with the Wilsons (which I wrongly atributed to the S5's wider front), but after Matts from SMT Sweden came to my house and moved the speakers 30cm forward, all the depth was back.
The only real drawback is speakers' weight, which makes borrowing them really difficoult (unless you have a very accomodating dealer).
IMO there is no speaker on the market today around $30k mark, which offers a better 'package'.
