Thank you all!
I have visited my local authorised KAWAI and YAMAHA dealer and I have played them both at the same store.
I played the CLP470 first, then moved to the CA63. Then tried the CA93, and finally the CLP280. Well, the difference is huge! Kawai's action is far better than the Yamaha's. Yamaha feels like plastic compared to Kawais keyboard.
The dealer has tried to convince me to go for the CA93 or wait for the CS9 instead; for this I would have to wait until March-April 2012, since they will not be available in Europe until then...
I would love to have a CS9, however, having played the CA93 and the CA63 I must say that the quality of the CA63 is more than enough for what Iam looking for, therefore, I am finally waiting until the end of January for the CS6!
I think the improved keyboard and the acoustic cabinet will make a better DP than the CA63, which I have already played and like it, so could say that I have fallen in love with it, and more with the looks of the CS6.
Only thing is that the speakers are better on the CA93, and obviously on the CS9, but I dont really need that much. The CA63(CS6) sounds beautiful and it is more than perfect, and Im only going to be studying on it and playing it at home, so dont really need more speakers power...
Thank you very much all for reading and your comments. I will keep you posted and... hopefully the end of January will come soon and I will post some pics for you all!
