Price Comparison

The Casio Privia PX-870 is priced at $999.00, while the Ktaxon 88 Key Keyboard Piano Set is significantly cheaper at $199.99. This makes the Ktaxon about 80% less expensive than the Casio. For beginners or those on a budget, the Ktaxon offers an attractive entry point into digital pianos without sacrificing essential features. However, the price difference reflects the varying quality and capabilities of each instrument, which is crucial to consider when making a choice.

Sound Quality

The Casio Privia PX-870 delivers an immersive grand piano sound with its advanced AiR Sound Source. This system provides rich detail, including key-off simulation and mechanical sounds, aimed at recreating the depth of a concert grand piano. In contrast, the Ktaxon features built-in stereo speakers that provide decent sound quality but may not capture the nuances and richness found in the Casio. Thus, for those who prioritize sound fidelity, the Casio stands out as the superior option.

Key Action

The Casio Privia PX-870 boasts an 88-key Tri-Sensor II Scaled Hammer Action keyboard. This feature provides an authentic touch with simulated ebony and ivory textures, offering remarkable feel and dynamic control. Conversely, the Ktaxon utilizes semi-weighted keys, which enhance rebound speed but may not provide the same level of realism as fully weighted keys. Musicians seeking a closer experience to playing an acoustic piano will likely prefer the Casio’s key action.

Learning Features

The Casio Privia PX-870 is built with learning in mind, offering features such as Duet Mode, dual headphone jacks, and 60 built-in songs. It also includes a 2-track MIDI recorder and Concert Play with orchestral backing tracks, making it an excellent tool for practice and performance. The Ktaxon, while equipped with a multi-functional panel that displays 15 functions, lacks the dedicated learning features that the Casio provides. For dedicated learners or aspiring musicians, the Casio offers a more comprehensive set of tools.

Design and Aesthetics

In terms of design, the Casio Privia PX-870 features a sleek and modern console style, which can complement various home decors. Its elegant design is not just visually appealing but also functional, with a sliding key cover. The Ktaxon, on the other hand, boasts a wood grain finish that resonates with home aesthetics, making it an attractive choice for those looking for a traditional look. While both pianos are stylish, the Casio may have a slight edge in overall elegance.

Connectivity Options

The Casio Privia PX-870 includes class-compliant USB-MIDI connectivity, allowing for easy plug-and-play with Mac, PC, iOS, or Android devices. This feature makes it user-friendly for those who want to connect to music software or apps. The Ktaxon also offers dual-mode connectivity and multimedia external function compatibility, allowing for wireless connections to musical apps. While both pianos provide connectivity options, the Casio's seamless USB-MIDI connection may appeal more to tech-savvy users.

Brand Reputation and Sales Rank

The Casio Privia PX-870 is ranked 14,122 in sales, reflecting its popularity among consumers who value high-quality digital pianos. In contrast, the Ktaxon is ranked higher at 2,851, which may indicate a strong appeal among beginners and casual players. Although the sales rank suggests that Ktaxon has a broader base of entry-level customers, Casio's long-standing reputation for quality in digital pianos gives it credibility among serious musicians.

Which should you buy?

Choosing between the Casio Privia PX-870 and the Ktaxon 88 Key Keyboard Piano Set ultimately depends on your priorities. If you are serious about your piano playing and seek a high-quality instrument with authentic sound and feel, the Casio at $999.00 is worth the investment. However, if you are a beginner or looking for a more budget-friendly option, the Ktaxon at $199.99 provides essential features that can cater to your needs without breaking the bank. Assess your budget, playing level, and desired features to make the best decision for your musical journey.
