Not an owner but I have done the same as @erik_squires. I spent some time with them at a dealer.
My experience was the speakers disappeared. They were standing next to Scansonics and Kaisers and I had to ask which speaker was playing. No localization at all. Soundstage had wonderful height and width. Detail is incredible and it is one of the Beryllium tweeter implementations I really like. They were very, very good. I did not ultimately buy them because they don't fit my taste perfectly, but they were very, very good
