I heard them at a local High-End store before they closed. They were set up very far apart, about 15 feet, on the long wall of a well treated room and being driven by a pair of monstrous Macintosh Tube amps which were being fed by a Mac CD player with a volume control. No preamp. The set-up was an experiment they were doing that day, for fun, to see how big of a soundstage they could get. The results were amazing. The soundstage was enormous and the depth was huge. It was very weird to hear a horn player eight feet off the floor with pinpoint position just off center. The speakers were not part of the soundstage. It was like they were unconnected. The tone was great and I had goosebumps for 10 minutes. I can't give you a professional review but I was very impressed. By admission though, I tend to see things positively. I can say that they were absolutely seamless speakers and they did nothing wrong.
