I wonder if that's SACD per se or just the sound of the Sony units. Art Dudley in Listener has commented that he hears almost no difference between the SACD playback of the several units he's reviewed, but I find it hard to imagine that there would not be a large difference, just as there is between CD players. When (if) we start seeing more high-end SACD players, I suspect we will hear a different SACD sound.
