I have heard both the FPB200 and KSA200s in other systems and the FPB200 in my system a few yrs ago. I loved the FPB in my system to be quite honest. Very smooth and dynamic. It had very good bass but I don't think it had the bass the KSA series has. The FPB sounded more refined than the 200s from what I remember in my buddies system. He preferred the 200s because he thought it sounded more open and powerful but that was in his system. He likes a more detailed sound so I guess it depends on what your looking for and the speakers you have. If I were to pick one or the other I would choose the FPB200 but I like a little more refined sound because I listen to dynamic types of music.
