Introduction to the Digital Pianos

When comparing the Casio PX-870 Privia Digital Piano and the Eastar EUP-100 88 Key Weighted Keyboard Piano, there are significant differences that cater to various types of musicians. The Casio PX-870 is priced at $899.00, while the Eastar EUP-100 is about 64% cheaper at $319.99. This price difference suggests that the two products serve distinct market segments, one targeting more serious players and the other catering to beginners.

Design and Aesthetics

The Casio PX-870 features a modern wooden cabinet design available in black, oak, or white finishes, which allows it to blend seamlessly with any decor. Its elegant appearance is complemented by a sliding key cover, enhancing its visual appeal. In contrast, the Eastar EUP-100 has a retro wood color that not only makes it an instrument but also a stylish centerpiece for a living space. While both pianos offer a polished look, the Casio’s more sophisticated design may attract those looking for a premium feel.

Key Action and Feel

The Casio PX-870 is equipped with 88 scaled, weighted hammer-action keys that simulate the touch of an acoustic piano. It boasts features like simulated ebony and ivory textures, enhancing the authentic playing experience. The Eastar EUP-100 also offers 88 fully weighted keys, making it suitable for beginners who want to emulate the feel of playing a grand piano. However, the PX-870's Tri-Sensor II Scaled Hammer Action provides a more nuanced touch response, which might appeal more to advanced players.

Sound Quality

Sound quality is a crucial element in any digital piano, and the Casio PX-870 excels with its new piano sound that includes detailed resonance and a powerful 4-speaker sound projection system. This setup delivers rich audio that fills the room, making it ideal for performances. On the other hand, the Eastar EUP-100, while offering decent sound for its price, does not match the immersive audio experience provided by the Casio, which includes 18 additional tones and 256 notes of polyphony.

Features and Functionality

The Casio PX-870 is packed with features including a built-in Music Library with 60 songs, duet mode for student-teacher interaction, and the ability to connect to devices via USB. It also includes recording capabilities and a variety of practice tools. Meanwhile, the Eastar EUP-100 offers practical features such as dual voice, split keyboard, and MIDI connectivity, which are useful for beginners. However, it lacks the extensive learning resources and performance capabilities found in the Casio, making it less versatile for advanced users.

Accessories and Bundles

The Casio PX-870 comes as a complete bundle, including a furniture bench, headphones, an instructional book, online lessons, and an instructional DVD, adding significant value for new players. In contrast, the Eastar EUP-100 includes a triple pedal, headphones, and piano stickers but does not offer the same level of comprehensive learning tools or accessories. This difference makes the Casio a more attractive option for those seeking a full package for learning and performing.

Performance and Suitability

For serious pianists or those looking to perform, the Casio PX-870's advanced features and superior sound quality make it a preferable option. Its sales rank of 13,806 reflects its popularity among consumers who appreciate its authenticity and enhanced performance capabilities. Conversely, the Eastar EUP-100, with a sales rank of 7,517, appeals more to beginners or casual players looking for an entry-level instrument that is affordable and functional.

Which should you buy?

Choosing between the Casio PX-870 Privia Digital Piano and the Eastar EUP-100 depends largely on your experience level and specific needs. The Casio is ideal for serious musicians seeking a realistic playing experience and extensive learning resources at a price of $899.00. Meanwhile, the Eastar, priced at $319.99, is a budget-friendly option that provides essential features suitable for beginners. Ultimately, if you are committed to advancing your piano skills, the Casio is worth the investment; however, if you are just starting out, the Eastar offers great value for the price.
