Let us hear the feedback from a person who bought the Casio hybrid digital grand piano GP-510 and who has had before the Casio GP-500.
From "L. v. Beethoven - Sonata No. 14, Op. 27 no. 2, movement 3 - Kateryna Titova on GP-510 - YouTube" at https://www.youtube.com/watch?v=hMt...wyuzpjmgkjuav51w03c010c.1572564644063059
3 weeks ago [from 2019/11/01]I've had my new Casio GP510 for a few days now and I really love it. I had the GP500 before but swapped it for an expensive, brand new, Yamaha C1X grand fitted with a silent system because I wanted a 'real' piano. I actually preferred the Casio so after much anguish I sold the Yamaha and I've gone back to another Casio. In my opinion the GP510 has a better base than a small acoustic grand piano (even an expensive one) it's also easier to play at a sensible volume level without disturbing people several rooms away.
2 weeks ago [from 2019/11/01]In your opinion, what are the differences between the GP-500 and the GP-510 on various aspects: piano sound, touch, etc.?

@Michael Not much difference really. Perhaps a slightly improved bass sound and slightly easier to play very quietly but as I no longer have the 500 to compare it to it's hard to be sure. For both versions the sound on the headphones is excellent and the sound on the piano's speakers is less good but not bad.
