Overview of the Casio PX-870 and Ktaxon 88 Key Keyboard Piano

The Casio PX-870 is priced at $899.00, while the Ktaxon 88 Key Keyboard Piano is significantly more budget-friendly at $199.99, making it about 78% cheaper. This stark price difference highlights the contrasting target audiences of these instruments. The Casio PX-870 is designed for serious pianists seeking a premium experience, while the Ktaxon appeals to beginners and casual players looking for an affordable option.

Design and Aesthetics

In terms of design, the Casio PX-870 features a stylish modern wooden cabinet that complements any décor, available in three finishes: black, oak, and white. Its elegant appearance is enhanced by a sliding key cover, making it a visually appealing addition to any room. On the other hand, the Ktaxon 88 Key Keyboard Piano has a more basic aesthetic, with a woodgrain finish that suits various home styles but lacks the same level of sophistication. While both instruments aim to fit into home environments, the Casio’s design is more refined and suitable for dedicated practice spaces.

Sound Quality

The sound quality of the Casio PX-870 is exceptional, boasting a powerful 4-speaker sound projection system designed to fill the room with rich, dynamic audio. It features an award-winning AiR Sound Source that includes a four-layer stereo grand piano sound, providing an immersive listening experience. In contrast, the Ktaxon piano, while equipped with dual stereo speakers, does not offer the same depth or fullness of sound. It simulates the hammering mechanism of traditional pianos but lacks the detailed resonance and richness found in the Casio. Thus, for audiophiles and those prioritizing sound, the PX-870 stands out clearly.

Key Action and Playability

The Casio PX-870 is equipped with 88 scaled, weighted hammer-action keys, providing an authentic touch that mimics a grand piano experience. Its Tri-Sensor II technology ensures expressiveness and responsiveness, making it ideal for nuanced performances. The Ktaxon, while featuring full-weighted keys that simulate a real touch, does not reach the same level of sophistication in key action. Its mechanism offers a decent playing experience, but serious players may find it less satisfying than the Casio. Therefore, for those focused on playability, the PX-870 is the superior choice.

Functionality and Features

The Casio PX-870 excels in functionality, offering 19 instrument tones, a 256-note polyphony, and a variety of recording and practice tools. It includes features like Duet Mode for teaching, a built-in music library with 60 songs, and advanced connectivity options, such as class-compliant USB connections for devices. In contrast, the Ktaxon offers a more simplified feature set, including a multi-functional LCD panel and Bluetooth connectivity for pairing with devices. While it caters well to beginners, it lacks the comprehensive features and versatility found in the Casio. For users who value extensive functionality, the PX-870 is undoubtedly the better option.

Accessories and Bundles

The Casio PX-870 comes as a complete bundle, including essential accessories like a furniture bench, headphones, an instructional book, online lessons, and a polishing cloth. This makes it an excellent value for those who require everything needed to start playing immediately. The Ktaxon also includes several accessories, such as a removable music stand, stereo headphones, and a cleaning cloth, but it lacks the extensive instructional materials provided with the Casio. Hence, for those seeking an all-in-one package, the PX-870 provides a more robust offering.

Pricing and Value

With the Casio PX-870 priced at $899.00 and the Ktaxon at $199.99, the Casio is about 78% more expensive. While the Ktaxon offers a great value for beginners or those on a tight budget, the PX-870 justifies its higher price with superior sound quality, playability, and features. The investment in the Casio is more likely to pay off for serious musicians looking for a long-term instrument that meets professional standards.

Which should you buy?

Ultimately, the choice between the Casio PX-870 and the Ktaxon 88 Key Keyboard Piano depends on your needs and budget. If you are a serious pianist looking for an authentic playing experience, rich sound quality, and extensive features, the Casio PX-870 is worth the investment. However, if you are a beginner or casual player in search of an affordable keyboard with essential features, the Ktaxon is a sensible option. Consider your priorities in playability, sound, and functionality to make the best choice for your musical journey.
