Extemas used to come up fairly regularly years ago, but no more. Early in the thread, someone mentioned Diapason Adamantes. There was a beautiful pair of the special edition ones for sale here a couple of months ago for a reasonable price that I couldn't afford. Anyway, for months the was a very nice pair of version III (the latest) on USAudiomart with stands (!) for $2200. I was waiting to sell something so I could buy them (sound familiar?), and the day that I had the money in hand, I emailed the seller...he sold them that day. My heart sank.
They are a truly great speaker. I was dying to hear them with my 300b amp. Maybe some day.
