text: which digital piano sound best (feels like a real grand acoustic piano) ? is it previa by casio, kawai digital, or clavinova by yamaha ? or any other ? it's a matter of personal preference. (and of course nothing beats a real piano.) but digital pianos are easier to maintain. i suggest going to the store and playing all these models. i personally like yamaha. i'd stay away from casio. don't know much about kawai. kurzweill and korg have some of the leading technologies as far as sounding like a piano is concerned. you'll want something truly weighted to feel like a grand piano.
