Design and Build Quality

When it comes to design and build quality, the Casio Privia PX-870 stands out with its elegant appearance and modern aesthetics. Its sleek console design not only enhances the visual appeal but also features a sliding key cover, making it a stylish addition to any room. Priced at $999.00, it embodies a premium feel that is often associated with higher-end digital pianos. In contrast, the Eastar EUP-100, priced at $319.99, adopts a more traditional retro wood finish that transforms it into a sophisticated centerpiece. While both instruments boast sturdy constructions, the Casio's design is more focused on elegance, while the Eastar emphasizes practicality and ease of use.

Sound Quality

The sound quality of the Casio Privia PX-870 is exceptional, thanks to its AiR Sound Source technology, which delivers rich, detailed sound that closely mimics a concert grand piano. With a powerful 40W 4-speaker sound system, it fills any space with immersive audio, making it suitable for performances and dynamic practice sessions. The Eastar EUP-100, while offering an 88-key weighted hammer action keyboard that simulates the touch of a real grand piano, lacks the same audio depth. It does, however, come equipped with versatile features such as Dual Voice and built-in metronome, enhancing the overall practice experience. The difference in sound systems reflects the price gap, with the Casio providing a premium sound experience for its higher price.

Key Action and Feel

The Casio Privia PX-870 features a Tri-Sensor II Scaled Hammer Action keyboard, designed to replicate the authentic touch of an acoustic piano. This ensures remarkable feel and superior dynamic control, which is crucial for expressive playing. On the other hand, the Eastar EUP-100 also offers an 88-key fully weighted keyboard, making it a suitable option for beginners looking to develop their skills. However, the key action may not provide the same level of responsiveness as the Casio's advanced mechanism. This notable difference in key feel can significantly affect the playing experience, especially for those who prioritize touch sensitivity and expressiveness in their practice.

Features and Learning Tools

In terms of features, the Casio Privia PX-870 is packed with practical tools that cater to learners and performers alike. It includes a duet mode, dual headphone jacks, 60 built-in songs, and a 2-track MIDI recorder, making it a robust option for both practice and performance. The Eastar EUP-100, while aimed at beginners, offers a variety of useful features such as recording capability, wireless connectivity, and a triple pedal setup. It also includes educational elements like piano stickers, which can aid new players. Although both pianos provide valuable features, the Casio's advanced learning tools and recording capabilities give it an edge, particularly for more serious students.

Connectivity Options

Connectivity options are another key consideration. The Casio Privia PX-870 features class-compliant USB-MIDI, allowing for easy plug-and-play functionality with various devices, including Mac, PC, iOS, and Android. This facilitates seamless integration with music software and educational apps, making it a versatile choice for tech-savvy users. In contrast, the Eastar EUP-100 also offers MIDI IN/OUT and wireless connectivity, providing flexibility for users who wish to connect to educational platforms. While both pianos cater to modern connectivity needs, the Casio’s more refined USB-MIDI implementation enhances its usability for a broader range of applications.

Price and Value

The price difference between these two digital pianos is significant, with the Casio Privia PX-870 retailing at $999.00 compared to the Eastar EUP-100's $319.99. This means that the Casio is about 68% more expensive than the Eastar. However, the higher price of the Casio reflects its superior sound quality, advanced features, and overall build quality. For a beginner or a casual player, the Eastar offers excellent value at a lower price point, providing essential features without breaking the bank. Ultimately, the choice depends on the buyer's budget and their commitment to learning or performing on a digital piano.

Brand Reputation

Brand reputation plays a crucial role in choosing a digital piano. Casio has a long-standing history of producing high-quality musical instruments and is known for its innovation in digital piano technology. The Privia line has consistently received positive reviews for its performance and features. Eastar, while a newer brand, has quickly gained recognition for its affordability and beginner-friendly instruments. The Eastar EUP-100 has achieved a bestseller rank of 7517, indicating a growing popularity among entry-level musicians. While both brands have their merits, Casio's established reputation may provide additional confidence for buyers looking for a long-term investment.

Which should you buy?

Choosing between the Casio Privia PX-870 and the Eastar EUP-100 ultimately depends on your specific needs, budget, and playing experience. The Casio offers a premium sound and build quality, making it ideal for serious players or those looking for an instrument that will grow with them. Its advanced features and elegant design justify its higher price. Conversely, the Eastar provides an excellent entry point for beginners who want a full-featured digital piano at a fraction of the cost. If you are just starting out or have budget constraints, the Eastar is a solid choice. However, for those seeking a long-term investment in their musical journey, the Casio Privia PX-870 stands out as the superior option.
