They were set up in a mastering studio, full of excellent quality pro gear like Lavry DA-924 + LE3000. IIRC power amps were Bryston, but I'm not 100% sure. The model was the previous one using black mid-woofers. Not that I had the chance to play my music or pay any "critical listening" whatever that is, but could get a grasp on their character. Rather impressive I must say. Those things can play loud and doing it without distortion. Cristal clear sound, a bit in the cold analytical side of things, but that could be due to many other things, including the amps. I suppose they're a very good tool for mastering, mixing and any professional application, but not that sure they'll give "musical bliss" in the Harbeth, Spendor, Quad way.
