UTILIZATION

Perfect for everyday use, for study or pleasure.

SOUNDS

2sons beautiful piano! Very realistic, really impressive.
Reverb sound, nuances evident after the game for everyone.
I mainly use the piano sounds for my music and violins. (I put the dual mode, superposition of two tones with setting a sound louder than the other following his desire).

OVERALL OPINION

I've had two weeks and I'm stoked!
I love the touch and piano sounds. And the furniture is beautiful.
3 years ago I began with a recital actylon (699 €), which was basic in all respects but it was my first "grand piano" since I left a portable keyboard! Then the year after I bought a casio CELVIANO AP 500 (1499 €): the sound was better, very good power 30w lais he was a little big, mahogany color was not very appropriate to my lounge and retro touch was soft. And now I find myself with a Yamaha YDP 140 (759 €), the best of three, and the cheapest!
I would do this choice without hesitation.
