Hi, i`ve been reading a lot of DPs on the web, and I got interested on the CASIO Privia px 200/800 and the YAMAHA DGX620.

The first question that came to my mind was: "whats the difference on the sound quality for the two models?", casio is now using a new technology called AIF that seems to sound great. On the other hand, yahama`s experience is very well known.

For a Classical music lover, which one is the better option in terms of quality sound?, which one would be the best option thinking in the touching response on the keys?

Thanks.

PD: My english it`s not my mother language, sorry if a made some mistakes.
