This may not help, but I just got a Phantom III (my FPB600 doesn't have CAST), on a recommendation from Patrick at Krell. I had a KRC-HR and was trying to decide between going to a KCT or saving up for a 202 or Phantom. I would think that based on my KRC to Phantom results, that you would gain in all parameters. My Phantom is more open, quicker, better soundstage with a more solid image, and more transparent as well.
Hope this helps,
Mike
