Design and Aesthetics

The Casio CDP-S360 is priced at $669.99, while the Yamaha DGX-670B is available for $749.99, making the Casio about 17% cheaper. The design of the CDP-S360 features a slim body with a depth of just 232 mm, allowing for easy transport and placement. Its minimalist aesthetic, available in black and red, provides a modern look. In contrast, the Yamaha DGX-670B also sports a sleek black finish but is designed to mimic traditional furniture with a more substantial presence. While both models are visually appealing, the Casio's compactness may be more suitable for smaller spaces or mobile musicians.

Keyboard Action

The Casio CDP-S360 utilizes a scaled hammer action keyboard, delivering a tactile experience akin to that of a grand piano. This feature is especially beneficial for players seeking an authentic touch, with its simulated ebony and ivory textures enhancing the feel. On the other hand, the Yamaha DGX-670B also employs a weighted keyboard action, where the keys are heavier in the lower register and lighter in the higher. This mimics the dynamics of an acoustic piano, making it ideal for practice and performance. Both keyboards are designed to provide realistic playing experiences, but the choice between them may come down to personal preference regarding feel and response.

Sound Quality

Sound quality is a crucial aspect of any digital piano, and both the Casio CDP-S360 and Yamaha DGX-670B excel in this domain. The Casio offers 700 tones, including a stereo grand piano sound, with 128-note polyphony that ensures even complex passages sound rich and full. In contrast, the Yamaha features CFX Stereo Sampling technology, replicating the sound of Yamaha's flagship CFX Full Concert Grand piano. It also boasts 630 instrument voices and 263 automatic accompaniment styles, allowing for a diverse range of musical expression. While both instruments deliver exceptional sound quality, the Yamaha may appeal more to those who appreciate a wider variety of instrument sounds.

Features and Functionality

Both digital pianos come equipped with a variety of features aimed at enhancing the user experience. The Casio CDP-S360 includes a built-in MIDI recorder with six tracks, allowing users to capture their performances easily. Additionally, it supports app connectivity with the CASIO Music Space app, enabling users to control settings via their smartphones. On the other hand, the Yamaha DGX-670B includes a built-in microphone jack and digital vocal effects, providing a unique opportunity for singers to accompany themselves. While both offer distinctive features, the choice may depend on whether the user prioritizes recording capabilities or vocal integration.

Learning Resources

When it comes to learning resources, the Casio CDP-S360 offers a comprehensive bundle that includes an instructional book, an Austin Bazaar Instructional DVD, and online lessons. This package is designed to support beginners in their musical journey. Conversely, the Yamaha DGX-670B features the “You Are The Artist” library, providing access to popular sheet music and scrolling note displays that simplify learning. While both pianos provide valuable resources for learners, the Casio's bundled offerings may give it an edge for those seeking structured guidance.

Portability

Portability is a strong suit for the Casio CDP-S360, weighing only 24 lbs and capable of running on six AA batteries, which makes it ideal for musicians on the go. This lightweight design, combined with its slim profile, allows for easy transport to gigs, rehearsals, or casual play. The Yamaha DGX-670B, while still portable, is slightly heavier and does not emphasize battery power as a feature. For those who prioritize mobility in their musical setup, the Casio is undeniably more convenient.

Price Comparison

The Casio CDP-S360 is priced at $669.99, whereas the Yamaha DGX-670B is available for $749.99. This pricing difference of $80 makes the Casio about 11% cheaper than the Yamaha. Given that the Casio also includes a comprehensive bundle of accessories, it offers a compelling value for those looking to maximize their investment. While the Yamaha provides a broader range of sounds and features, the price difference may influence budget-conscious buyers.

Which should you buy?

Choosing between the Casio CDP-S360 and the Yamaha DGX-670B ultimately depends on your specific needs and preferences. If you prioritize portability, a comprehensive learning bundle, and a lower price point, the Casio CDP-S360 is the clear choice. However, if you seek a richer variety of sounds and features aimed at vocal performance, the Yamaha DGX-670B may better suit your needs. Both instruments offer excellent quality and functionality, making either a worthy addition to your musical journey.
