There can be not doubt, the KN5000 was at the time by far the best and most advanced keyboard on the market. The long waiting lists showed that clearly. I think I waited six month for mine. Time has passed and it still is nowadays a wonderful instrument I adore playing whenever I get a chance when visiting my Swiss base.
In Spain I enjoy the mighty KN7000 with number one expansion board. These two keyboards are IMHO absolute top.
