sorry, nothing to do with brainwashing, or with high prices here.

On this side of the atlantic the kn is better value than yamaha, the market penetration high and pricing is quite different from the states.

There is a section of perhaps mature and more affluent customers that have never been disappointed with the top keyboards, and will regularly change models because they like them.
Some try yamaha or others and come back after a few weeks and change them for kn because they can use them that much easier. These people may not be professional players (although I know many pros who prefer the kn) but they know what they like and enjoy. They are not brainwashed into anything.

Maybe you are a little brainwashed into believing that the kn7000 can "NOT be ahead of the pack" when you have never seen one yet?
