The best digital piano is one that can grow with a musician as they progress. When a pianist’s skill level rises, they require a keyboard action built for more serious playing. The Arius YDP-163 features Graded Hammer 3 keyboard action with three sensors and synthetic ivory key tops, giving the performer a dynamic response and authentic feel. The Pure CF Sound Engine on the YDP-163 expressively delivers the Yamaha CFIIIS concert grand piano tone combined with a powerful 20W + 20W amplifier and speaker system. With 192 note polyphony, many of the most complex piano compositions can be played without dropped notes while sustained passages ring through faithfully.
