Price Comparison
The Eastar EUP-100 is priced at $319.99, making it about 57% cheaper than the Yamaha DGX-670B, which retails for $749.99. This significant price difference may appeal to beginner pianists or those on a tighter budget. For a high-quality instrument, the Eastar offers a solid entry-level option without the hefty investment required for the Yamaha. The lower price of the Eastar does not compromise on features, providing essential tools for new musicians, while the Yamaha brings a plethora of advanced functionalities that justify its higher cost.
Target Audience
The Eastar EUP-100 is tailored for beginners, featuring a weighted hammer action keyboard that simulates a grand piano's touch. This makes it an ideal choice for those just starting their musical journey. In contrast, the Yamaha DGX-670B caters to a broader audience, including intermediate and advanced players, offering a wealth of features designed to enhance musical expression and creativity. With 630 instrument voices and 263 automatic accompaniment styles, the Yamaha is well-suited for performers looking to create a more dynamic playing experience.
Features and Functionality
Both pianos come packed with features, but they cater to different aspects of playing. The Eastar EUP-100 includes a variety of functions such as Dual Voice and Split Keyboard, which are perfect for practice and experimentation. Additionally, it offers MIDI IN/OUT capabilities, allowing for connection to educational apps. On the other hand, the Yamaha DGX-670B stands out with its CFX Stereo Sampling, providing exceptional sound quality that replicates the resonance of a full concert grand piano. The variety of instrument voices and styles on the Yamaha significantly broadens the creative possibilities for users.
Design and Aesthetics
The Eastar EUP-100 boasts a beautiful wood finish that transforms it from merely an instrument to an elegant centerpiece suitable for any room. Its design offers practicality without sacrificing aesthetics, making it a stylish addition to a living space. The Yamaha DGX-670B, while slightly more utilitarian, focuses on functionality, featuring a compact design that is versatile for different setups. Users may prefer the Eastar for a more traditional piano look or the Yamaha for its modern convenience and professional appeal.
Sound Quality
When it comes to sound, the Yamaha DGX-670B has a clear edge due to its advanced sampling technology, delivering the rich tones of a concert grand piano. This high-fidelity sound can enhance the playing experience, making it more engaging for performers. The Eastar EUP-100, while providing a respectable sound quality, does not match the Yamaha's depth and variety. For those who prioritize sound quality in their practice and performances, the Yamaha is likely the better choice despite its higher price.
Assembly and Portability
The Eastar EUP-100 is designed for straightforward assembly, making it accessible for beginners who may be intimidated by more complex setups. Its substantial weight ensures stability during play, but it may not be as portable as lighter models. In contrast, the Yamaha DGX-670B is relatively easy to transport, appealing to musicians who may frequently move their equipment. Although both pianos have their strengths in assembly, potential buyers should consider their needs for portability versus a solid setup.
Brand Reputation and Sales Rank
In terms of brand reputation, Yamaha is a well-established name in the music industry, known for producing high-quality instruments that cater to a range of skill levels. The Yamaha DGX-670B has a sales rank of 2,557, indicating a strong presence in the market. The Eastar EUP-100, with a sales rank of 7,517, is also gaining traction, particularly among beginners. While Yamaha has an edge in brand recognition, Eastar is carving out its niche with affordable offerings that do not sacrifice quality.

If you're a beginner seeking a budget-friendly piano with essential features, the Eastar EUP-100, at $319.99, is a fantastic option.
