Dimension comparison
Pricing and Value
The Yamaha P71 is significantly cheaper than the Yamaha DGX-670B, making it a more budget-friendly option for musicians. Priced at $429.99, the P71 is about 43% less expensive than the DGX-670B, which retails for $749.99. This price difference of $320 may make the P71 more appealing for beginners or those who are unsure about investing heavily in a digital piano. However, while the P71 is more affordable, it’s important to consider what features and capabilities each model offers in relation to their price.
Sound Quality
Sound quality is a strong point for both models, but the Yamaha DGX-670B excels with its advanced features. The DGX-670B offers the CFX Stereo Sampling, which faithfully reproduces the sound of Yamaha's flagship CFX Full Concert Grand, providing rich tones and natural resonance. In comparison, the P71 features 10 unique voices, including the sound of a Yamaha grand piano, though it may not have the same depth and nuance as the DGX-670B’s sound. For serious musicians seeking a high-fidelity experience, the DGX-670B’s superior sound may justify the higher price.
Key Action and Feel
The key action and feel of both pianos cater to different playing styles and preferences. The Yamaha DGX-670B features weighted keys that offer a heavier touch on the low end and a lighter touch on the high end, mimicking an acoustic piano's feel. This design makes it ideal for practice and performance alike. Meanwhile, the P71 also boasts weighted action, providing a touch-sensitive experience for expressive playing. While both keyboards deliver a quality playing experience, the DGX-670B's adaptive key action offers a more authentic piano feel, which is crucial for pianists looking to hone their skills.
Features and Functionality
In terms of features, the Yamaha DGX-670B truly shines with its extensive offerings. It includes 630 instrument voices and 263 automatic accompaniment styles, allowing for a more dynamic and interactive playing experience. Additionally, it has a built-in microphone jack for vocal effects and access to Yamaha’s “You Are The Artist” library for song learning. Conversely, the P71 is more streamlined with simpler functionality, including a dual mode to blend two voices. While the P71's features are sufficient for beginners or casual players, the DGX-670B's versatility is unmatched, making it better suited for those looking to explore a wide range of musical styles.
Portability and Design
Both the Yamaha DGX-670B and the P71 are designed with portability in mind, but they serve different purposes. The P71, being more compact and lightweight, is ideal for home use and easy transport, making it a great choice for students or casual players who may need to move it often. In contrast, the DGX-670B, while still portable, is designed more as a feature-rich instrument for performance settings, which may require a more substantial setup. Thus, if portability is your main concern, the P71 may be the better choice, but if you are looking for a performance-oriented instrument, the DGX-670B is worth the extra weight.
Learning and Support Features
The Yamaha DGX-670B offers more extensive learning resources than the P71, which can benefit aspiring musicians. Its built-in Score Display allows users to follow along with scrolling notes, making it easier to learn new pieces. Additionally, the DGX-670B's compatibility with Yamaha music apps enhances the learning experience significantly. The P71, while it provides essential features for practice, lacks the interactive learning tools that the DGX-670B offers. For serious students or those who appreciate a rich learning environment, the DGX-670B is likely the better investment.
Customer Reception
In terms of customer reception, the Yamaha P71 has a higher sales rank, coming in at 904, compared to the DGX-670B’s rank of 2557. This suggests that the P71 is favored among consumers, potentially due to its pricing and straightforward features. However, the DGX-670B's additional features and superior sound quality may attract a different segment of the market, particularly those who are more serious about their music. Understanding the reasons behind these ranks can help potential buyers decide which model meets their needs better.
Which should you buy?
Choosing between the Yamaha DGX-670B and the Yamaha P71 ultimately depends on your specific needs as a musician. If you are looking for a more affordable option with solid features for learning and casual play, the P71 is an excellent choice at $429.99. However, if you are serious about your musical journey and desire superior sound quality, extensive features, and a more authentic piano feel, the DGX-670B at $749.99 is well worth the investment. Each piano caters to different types of players, so consider your priorities before making a decision.
