Yamaha YDP-S51 review | Digital Piano Review Guide

digitalpianoreviewguide.com

The Yamaha YDP-S51 stands out with its stunning design and quality sound, making it a worthy contender in the digital piano market. Its Graded Hammer keyboard action and Pure CF Sound Engine deliver an authentic playing experience, though some may find the key action a notch below Yamaha's higher-end models. While the limited sound selection of just ten voices might disappoint more adventurous players, the clarity and richness of the tones available make up for it. With a hefty price tag that can be daunting, savvy shoppers can find it at a more reasonable price online. Overall, the YDP-S51 is a beautiful and capable piano, perfect for serious musicians looking to enhance their home setup, despite a few compromises.

Yamaha YDP S51 review - Arius YDP-S51

yamaha-keyboard-guide.com

While the Yamaha ARIUS YDP-S51 delivers impressive sound quality akin to the esteemed Clavinova series, its cabinet design leaves much to be desired. The Graded Hammer keyboard offers an authentic playing experience with nuanced touch sensitivity, making it suitable for serious pianists. However, the reviewer suggests that potential buyers may want to consider the YDP-162 for just $200 more, which may provide better overall value. With solid features and a rich sound, the YDP-S51 is a commendable choice, but its aesthetics and pricing may deter some.

REVIEW - Yamaha YDP142, YDP162, YDPS51 Digital Pianos

azpianoreviews.com

The Yamaha YDP-S51 offers solid features and an attractive design, but it doesn't fully excel in key action realism compared to competitors. While the GH graded hammer action provides a decent weighted feel, the stiffness may not satisfy players used to more responsive keys. The sound system, while improved over its predecessor, struggles to deliver the fullness found in other models. It’s a commendable option for beginners and casual players, but more experienced musicians may find it lacking in authenticity. If you're considering the YDP-S51, also explore alternatives like the Kawai KDP90 or Roland RP401R for potentially better key action and sound quality. Ultimately, it serves its purpose well in the under $2000 category, but the competition may offer greater value.
