I was interested because at first glance it looks really impressive. I sat down with it in the store and tried it on. The sound is quite acceptable - it looks like it uses two-layer sampled live instrument samples. I don't know, but it gave me a very realistic piano sound. I just skimmed through the rest of the sounds. El. the piano and strings are decent, the other sounds are more authentic, but you have to remember that it's mainly a piano, not a keyboard. Additional functions such as a metronome and a record player will please you especially during practice. I would rate the simulation of the hammer mechanics at 6 out of ten compared to the YAMAHA. I was pleasantly surprised by the solid resistance of the keys and the decent return. If I hadn't tried the Clavinova before, I might not have even noticed it, but I can definitely feel the difference compared to the YAMAHA. On the other hand - the price must be taken into account, and taking into account this important factor, I conclude that it is a very good instrument for beginner pianists, but it can also satisfy the needs of advanced players
