I had CTK-6200 Keyboard regarding this keyboard Yamaha already taken at the review of the Casio, the PSR-433. I wavered between the two devices and initially decided in favor of Casio, simply because it better like it in the photos. Quite incidentally, this impression was confirmed in kind too, but the Yamaha looks better than it appears in the photos. Feast for the eyes, but it must also work well. Here was the Casio, quite unlike the Yamaha PSR-433 an embarrassing weakness. FIS & Co, in other words, the black keys have significant side game. This is the feeling when playing a piece far as it is otherwise known only from cheap keyboards. The white keys on the other hand have the Casio a clean leadership and can play perfectly. Maybe even a bit better than the Yamaha. I was annoyed there after a few days, however, so the choice then but fell on the Yamaha Board. I am not yet firm enough to now go into all the functions of both boards can. Everyone likes to look at the individual advanced equipment and then make his choice. One or the other board may have precisely the Austattungsmerkmal, which is the important buyers. Otherwise, both giving anything away. The piano sound if you might take this as a reference, is both quite excellent. Not the same, but equally beautiful. To my ears at least.
The processing of the PSR-433 outstanding. It crunches and cracks nothing. The housing acts as solid as one would expect from a keyboard in this price range. Mainly because it is designated as a portable. I bought it on the spot at Musikhaus Kirstein, which offers your orders here on Amazon. The display should have been a bigger track and also is the one from Casio something chic and easier to read. But while playing you look actually eh on the notes. I have not a single complaint. 5 Stars
