Alan Sircom just wrote a very favorable review in Hi Fi+.
I drove to SSI in Montreal last month to hear them, and they were very disappointing. It was hard to tell whether the terrible sound was caused by the room, the electronics, or the speakers, and given Mr. Sircom's review, I'm thinking the speakers were not the problem. Stereophile commented on the poor sound generally in the hotel rooms, so let's give SF the benefit of the doubt.
I hope to hear them in NYC at Stereo Exchange, but they're also at David Lewis in Philadelphia. And I think they're $35,000. You could also hear them at Son or Filtronique in Montreal, but that's the dealer who set up the room for SSI, so the sound may not be ideal.
