Overview of the Casio PX-870 and Ktaxon 88 Key Keyboard Piano Set
The Casio PX-870 Privia Digital Piano is a premium option at $899.00, while the Ktaxon 88 Key Keyboard Piano Set offers a budget-friendly alternative at $199.99. This price difference of about 78% reflects the differences in features and build quality, making each option suitable for different types of players.
Casio’s PX-870 is designed for those seeking an authentic playing experience, featuring a stunning sound quality with a wide range of tones, along with a stylish wooden cabinet. In contrast, Ktaxon’s 88 Key Keyboard Piano Set is more focused on functionality for beginners, providing a semi-weighted key action that is responsive yet less premium than the fully weighted keys of the Casio.
Key Feel and Performance
The Casio PX-870 boasts 88 scaled, weighted hammer-action keys that simulate the textures of ebony and ivory, offering an incredibly realistic playing experience. This is ideal for players who prioritize the authentic feel of a grand piano. The PX-870 also features a Tri-Sensor II Scaled Hammer Action, which enhances expressiveness across the entire key range.
On the other hand, the Ktaxon 88 Key Keyboard Piano Set employs semi-weighted keys that provide a balance between ease of play and responsiveness. While it may not deliver the same level of authenticity as the Casio, it is still a solid choice for beginners who are getting accustomed to piano playing.
Sound Quality and Features
In terms of sound quality, the Casio PX-870 shines with its new piano sound that includes detailed resonance and a powerful 4-speaker system, producing a rich audio experience. It offers 19 instrument tones and 256 notes of polyphony, ensuring that even complex pieces sound natural.
Conversely, the Ktaxon keyboard features dual stereo speakers and supports up to 64-note polyphony. It comes equipped with 128 rhythms and 128 GM tones. While it may not match the audio depth of the PX-870, it caters well to beginners with multiple sound options and functionalities.
Design and Aesthetics
The Casio PX-870 is tailored for an elegant look, available in black, oak, or white finishes. Its compact wooden cabinet with a sliding key cover makes it a stylish addition to any room, appealing to users who value aesthetics as much as functionality.
In contrast, the Ktaxon 88 Key Keyboard Piano Set also features a wood grain design that complements various home decors. Its bench is adjustable in height, allowing users to find their most comfortable position, enhancing their playing experience. However, it lacks the premium feel of the Casio's design.
Connectivity and Compatibility
The Casio PX-870 offers a higher level of connectivity, featuring class-compliant USB connectivity that allows for easy connection to PCs, Macs, iOS, or Android devices without requiring additional drivers. This is ideal for tech-savvy users who want to integrate their music into digital platforms.
The Ktaxon keyboard also has dual-mode connectivity, which includes multimedia external functions and MIDI support. This allows users to connect to musical apps, but may not have the same seamless integration as the Casio. This is a consideration for users who may want to expand their digital music capabilities.
Additional Features and Accessories
The Casio PX-870 comes as a complete bundle, including 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.
On the other hand, while the Ktaxon 88 Key Keyboard Piano Set includes a multi-adjustable height bench, it does not come with additional accessories. This may be a drawback for those looking for a complete starter package, although its lower price point may compensate for this.
Bestselling Status
The Casio PX-870 holds a bestseller rank of 13,806, indicating a solid reputation among consumers seeking high-quality digital pianos. Its features and authenticity appeal to serious players. Meanwhile, the Ktaxon keyboard ranks at 2,851, suggesting that it is well-regarded among budget-conscious beginners who value its multifunctional capabilities.
Which should you buy?
Ultimately, the choice between the Casio PX-870 and the Ktaxon 88 Key Keyboard Piano Set hinges on your playing level and preferences. If you are an advanced player looking for an authentic piano experience with superior sound quality and a wealth of features, the Casio PX-870 is worth the investment at $899.00. In contrast, if you are a beginner or on a tight budget, the Ktaxon 88 Key Keyboard Piano Set at $199.99 provides a solid entry point into the world of digital pianos, despite its limitations in sound quality and features.
