Kawai ES-920 B

Digital piano purchased for home use and for exercise.
Aesthetically very nice, but my unit had some not negligible flaws.
The action presents differences between keys (with some even noisier than others), moreover the sound reproduction through the internal speakers is powerful but produces large and annoying distortions of the sound, probably due to the vibrations and resonances of the plastic materials used to save weight compared to its ancestor, the ES8, which made extensive use of metal.
The sound of the samples, especially the EX Concert Grand, are truly adorable.
It is a pity that the piano is ruined by a good but uneven mechanics, and by an audio sector that cannot express its full potential.
I don't know if I received a faulty unit or this is true for every KAWAI ES920, but this is what i got.

PROS:
Clean and pleasant design
Many functions
High-quality piano sound samples
Action of discreet workmanship

CONS
Inhomogeneous mechanics
Powerful internal speakers that produce intolerable vibrations in the instrument body
