Overview of the Casio PX-870 Privia Digital Piano

The Casio PX-870 Privia Digital Piano is a premium instrument priced at $899.00. This model is designed to provide an authentic grand piano experience, featuring 88 scaled, weighted hammer-action keys. It stands out with its high-quality sound projection system and a comprehensive accessory bundle, making it ideal for both students and seasoned players. The PX-870 has a bestseller rank of 13,806, indicating its popularity among consumers seeking a reliable digital piano.

Overview of the Weighted Piano 88-Key Digital Piano

In contrast, the Weighted Piano 88-Key Digital Piano offers a more budget-friendly option at $189.00, making it about 79% cheaper than the Casio model. This electric piano also features 88 keys with hammer action, but its sound capabilities and accessory offerings are comparatively limited. With a bestseller rank of 8,016, it is favored for its affordability and portability, appealing to beginner players and those looking for a simple digital piano solution.

Sound Quality Comparison

The sound quality of the Casio PX-870 is notably superior, featuring a new piano sound with detailed resonance and a 4-speaker sound projection system that fills a room with rich audio. It includes 19 instrument tones and 256 notes of polyphony, which ensures that complex performances sound natural. On the other hand, the Weighted Piano boasts 900 tones and 128 polyphonies, but it lacks the immersive sound projection technology found in the Casio. The PX-870's advanced sound features make it a better choice for serious musicians seeking a more authentic playing experience.

Key Action and Feel

Both pianos feature 88-key weighted keyboards, but the feel and responsiveness differ significantly. The Casio PX-870 has acclaimed Tri-Sensor II Scaled Hammer Action keys that provide an expressive touch, enhanced by simulated ebony and ivory textures. This key action is designed to replicate a grand piano experience accurately. Conversely, the Weighted Piano's hammer action is described as suitable for developing touch sensitivity but does not quite match the advanced technology of Casio's keys. For those prioritizing key feel, the PX-870 is the clear winner.

Connectivity and Features

When it comes to connectivity, the Casio PX-870 allows for class-compliant USB connections to PCs and mobile devices, making it versatile for modern usage. It also features headphone jacks for silent practice and a MIDI recorder for recording performances. The Weighted Piano offers USB/MIDI connectivity as well, but lacks the extensive features that enhance the user experience found in the Casio. The additional functionalities in the PX-870 make it more appealing for those looking to integrate technology into their practice.

Aesthetic and Design

The design of the Casio PX-870 is aesthetically pleasing, available in black, oak, or white finishes, with a modern cabinet and sliding key cover that fits well in any decor. It is designed to be both functional and stylish. In contrast, the Weighted Piano has a minimalist design that is compact and lightweight, weighing approximately 25.8 pounds. While it adds a classic touch to a room, it may not offer the same degree of elegance as the Casio. For those who value design, the PX-870 is more visually appealing.

Accessories and Bundle Offerings

The Casio PX-870 comes as a complete bundle that includes a furniture bench, headphones, an instructional book, online lessons, an instructional DVD, and a polishing cloth. This comprehensive package adds significant value to the purchase, especially for beginners. The Weighted Piano, however, does not include any additional accessories in its base offering. For consumers looking for a complete setup, the PX-870 provides a more attractive package, while the Weighted Piano leaves buyers to source accessories separately.

Which should you buy?

Choosing between the Casio PX-870 Privia Digital Piano and the Weighted Piano 88-Key Digital Piano largely depends on your budget and specific needs. The Casio offers superior sound quality, key action, and a complete accessory bundle at a price of $899.00, making it suitable for serious musicians. Conversely, the Weighted Piano presents a very affordable option at $189.00, ideal for beginners or those seeking a simple, portable instrument. If you're looking for a high-quality digital piano with a realistic playing experience, the PX-870 is the better investment. However, for those on a tight budget or just starting out, the Weighted Piano remains a viable choice.
