Design & Build Quality
Yamaha P-525: Premium, Minimalist & Portable
The Yamaha P-525 continues the sleek and modern aesthetic of Yamaha’s P-series, but with noticeable refinements that enhance its premium appeal. At first glance, it retains the minimalist design that the P-series is known for, but a closer inspection reveals several subtle but important upgrades that make it stand out.
Materials & Construction
The body of the P-525 is made of high-quality plastic with a matte finish, giving it a sleek, professional appearance. Unlike some budget digital pianos that use glossy plastic, the matte surface prevents fingerprints and smudges, ensuring it remains clean and elegant over time.
One of the biggest improvements over its predecessor, the P-515, is the better durability of the materials used. The side panels have a more refined texture, making the P-525 feel even more premium. Although it doesn’t have a full wooden cabinet like some console-style digital pianos, the solid construction gives it a sturdy, reliable feel that will withstand years of use.
The control panel is streamlined and elegant, with well-placed buttons and an LCD screen that is clear and easy to read. Unlike more complex arranger keyboards, the P-525 keeps things simple—focusing on intuitive usability rather than an overwhelming number of controls.
Portability & Dimensions
One of the defining features of the P-series is portability, and the P-525 follows in that tradition. While it is slightly heavier than some entry-level portable digital pianos, it remains light enough to transport comfortably, making it an excellent choice for gigging musicians or those who frequently move their instrument.
- Width: 1,332 mm (52.4″)
- Depth: 376 mm (14.8″)
- Height: 166 mm (6.5″)
- Weight: 22.0 kg (48.5 lbs)
Compared to its predecessor (P-515, which weighs 22.0 kg), the P-525 maintains the same weight, despite its improved internal components and enhanced sound system.
While the P-525 is designed for portability, it is also well-suited for home use when paired with the optional L-515 wooden stand and LP-1 three-pedal unit. This transforms the P-525 into a more traditional upright-style digital piano, making it look and feel like a console model while maintaining the ability to detach and move it easily when needed.
User Interface & Controls
The control panel on the P-525 is intuitive and uncluttered, featuring:
- A small monochrome LCD screen for navigation
- Clearly labeled buttons for voice selection, functions, and settings
- A simple volume knob for easy adjustment
Unlike the DGX-670, which has a large color screen and more physical controls, the P-525 takes a minimalist approach, making it ideal for players who prefer a distraction-free experience focused purely on playing the piano.
Another nice touch is the textured key surface on the black keys, which reduces finger slippage and makes playing more comfortable over long practice sessions.
Yamaha DGX-670: Stylish & Feature-Rich
The Yamaha DGX-670, in contrast, is a larger and more feature-packed instrument, designed as a hybrid between a digital piano and an arranger keyboard. It trades portability for expanded functionality, making it a great choice for home users who want a complete digital piano workstation.
Materials & Construction
The DGX-670 has a more substantial, solid feel, with a chassis that is heavier and more robust than the P-525. The body is primarily made of high-quality plastic, with a matte finish on the main panel to reduce glare and fingerprints.
A notable design feature of the DGX-670 is its integrated music stand, which is sturdier than typical detachable stands. This makes it an excellent choice for users who frequently read sheet music or use a tablet for digital scores.
One of the most noticeable differences compared to the P-525 is the control panel layout. The DGX-670 has a much larger number of buttons, a bigger color LCD screen, and a more complex user interface due to its arranger features, accompaniment styles, and soundbank selections.
Portability & Dimensions
Because of its arranger-style features and larger control panel, the DGX-670 is wider and deeper than the P-525, making it less portable.
- Width: 1,399 mm (55.1″)
- Depth: 445 mm (17.5″)
- Height: 151 mm (5.9″)
- Weight: 21.4 kg (47.2 lbs)
Despite being slightly lighter than the P-525, the larger frame and deeper body make it bulkier, so transporting it frequently is less convenient. It is clearly designed for home use rather than for stage or gigging musicians.
For a more permanent setup, Yamaha offers an optional wooden furniture stand (L-300) and a matching LP-1 pedal unit, turning it into a stylish home digital piano.
User Interface & Controls
Unlike the P-525, which prioritizes simplicity, the DGX-670 offers an extensive control panel with a variety of buttons, dials, and a full-color LCD screen.
Key design elements include:
- A large 4.3-inch color LCD display
- Dedicated buttons for selecting voices, styles, and accompaniment features
- A microphone input with vocal effects, ideal for singers
- A joystick-style pitch bend control
The color LCD screen is a huge advantage for navigating the hundreds of built-in sounds, accompaniment styles, and advanced functions. It also displays sheet music and lyrics, making it a great tool for learning and performing.
However, for users who only want to focus on playing the piano, the complexity of the DGX-670’s interface might be overwhelming compared to the straightforward and piano-centric layout of the P-525.
Design Comparison: Which One is Better?
| Feature | Yamaha P-525 | Yamaha DGX-670 |
|---|---|---|

Keyboard & Playing Experience
The keyboard action is one of the most important factors when choosing a digital piano. For intermediate players and general consumers, the feel, responsiveness, and realism of the keys make a significant difference in playing enjoyment and skill development.
The Yamaha P-525 and Yamaha DGX-670 use different key actions, resulting in noticeably different playing experiences. The P-525 is designed to offer a high-end, authentic grand piano feel, while the DGX-670 uses a more standard digital piano action that prioritizes affordability and versatility.
Let’s break down their differences in detail.
Yamaha P-525: GrandTouch-S Keyboard with Wooden Keys
Key Action & Mechanics
The Yamaha P-525 features Yamaha’s GrandTouch-S keyboard action, a significant upgrade over the Graded Hammer Standard (GHS) action found in the DGX-670.
The GrandTouch-S action is a scaled-down version of Yamaha’s flagship GrandTouch action, which is used in their premium Clavinova series. This means that it offers a more realistic touch and key response, closely resembling that of an acoustic grand piano.
Here are the key mechanical features of the GrandTouch-S action:
- Wooden White Keys: The white keys are made of real wood, making them feel more solid, textured, and premium under the fingers.
- Synthetic Ebony & Ivory Keytops: The black keys have a textured matte finish, preventing slippage and providing a more comfortable touch, similar to an acoustic grand piano.
- Longer Key Pivot Length: The longer pivot length improves balance, meaning you get even key resistance no matter where you press. This is especially noticeable when playing near the back of the keys (something that feels unnatural on many digital pianos with shorter pivot lengths).
- Escapement Mechanism: The P-525 replicates the subtle “notch” sensation of an acoustic piano’s escapement, which occurs when playing softly. This adds to the overall realism of the touch response.
- 5 Levels of Touch Sensitivity: The keyboard supports five different touch response settings, allowing you to adjust how the piano reacts to your playing dynamics.
Playing Experience
When playing the P-525, the keys feel highly responsive, firm, and expressive. The wooden keys provide a solid feel, and the escapement mechanism makes soft playing more natural.
Because of the longer pivot length, playing fast passages and complex pieces feels much more comfortable than on keyboards with shorter key actions. This makes the P-525 a great choice for intermediate to advanced players who need precision and expressiveness.
For classical and jazz pianists, the GrandTouch-S action is a major advantage, as it allows for a greater range of expression and subtle dynamic control.
However, if you’re a beginner or a casual player, you might not notice these subtle refinements as much—though they certainly contribute to an overall superior playing experience.
Yamaha DGX-670: Graded Hammer Standard (GHS) Keyboard
Key Action & Mechanics
The Yamaha DGX-670 uses Yamaha’s Graded Hammer Standard (GHS) action, which is a more basic key action found in Yamaha’s entry-level and mid-range digital pianos.
Unlike the GrandTouch-S action on the P-525, the GHS action is designed for affordability rather than realism.
Here are the key mechanical features of the GHS action:
- Plastic Keys: Unlike the P-525, the DGX-670’s keys are entirely plastic. While the black keys have a matte finish to reduce slipperiness, the white keys are smooth plastic, which can feel less premium under the fingers.
- Graded Hammer Action: The keys are heavier in the lower register and lighter in the higher register, mimicking the behavior of an acoustic piano. However, the weight transition is not as refined as in the P-525’s GrandTouch-S action.
- No Escapement Mechanism: The GHS action does not include escapement, meaning you won’t get the subtle “notch” sensation that’s present on acoustic grand pianos.
- 4 Levels of Touch Sensitivity: The DGX-670 offers four touch response settings, allowing you to adjust how the keys respond to your playing dynamics.
Playing Experience
The GHS action is decent for beginners and casual players, but for intermediate to advanced players, it feels lighter and less refined compared to the GrandTouch-S action on the P-525.
- Fast playing feels slightly sluggish, as the key return is not as quick or responsive as the P-525.
- Key resistance is lighter, making it easier for beginners but less satisfying for pianists who want more control over dynamics.
- Repetition and trills are more difficult to execute smoothly, as the keys lack the weight and balance of the P-525.
While the DGX-670’s GHS action is suitable for practice, it doesn’t quite capture the full expressiveness of an acoustic piano.
However, one advantage of the GHS action is that it is lighter, making the DGX-670 more approachable for younger players or those who prefer a less demanding key action.
Key Action Comparison: Which One Feels More Like a Real Piano?
| Feature | Yamaha P-525 (GrandTouch-S) | Yamaha DGX-670 (GHS) |
|---|---|---|
| Key Material | ✅ Wooden white keys, synthetic black keys | ❌ Plastic keys |
| Touch Sensitivity | ✅ 5 levels (better responsiveness) | ❌ 4 levels |
| Escapement Mechanism | ✅ Yes (adds realism) | ❌ No |
| Key Weighting | ✅ Graded, balanced, and responsive | ✅ Graded, but less refined |
| Pivot Length | ✅ Longer (better balance) | ❌ Shorter (less control) |
| Feel for Classical & Jazz | ✅ Excellent | ❌ Decent but less expressive |
| Feel for Pop & Synth | ✅ Great but may feel heavy | ✅ Good, especially for beginners |
| Best For | ✅ Intermediate to advanced pianists | ✅ Beginners to intermediate players |
The Yamaha P-525 is the clear winner in terms of key feel, realism, and overall playing experience. Its GrandTouch-S action with wooden keys makes it feel closer to a real grand piano.
However, the Yamaha DGX-670 still provides a decent playing experience for beginners and casual players. If you’re not concerned with high-end key action and just need a solid digital piano for learning or casual playing, the GHS action will still get the job done.
Final Verdict on Keyboard & Playing Experience
- If you want the most realistic key action, the Yamaha P-525 is the superior choice.
- If you are a beginner or casual player who doesn’t need advanced realism, the DGX-670 is still a great option.
Who Should Choose Which?
- Choose the P-525 if: You’re a serious pianist, need realistic grand piano touch, or plan to develop advanced piano techniques.
- Choose the DGX-670 if: You want a lighter, easier-to-play keyboard, are on a budget, or prefer versatility over authentic piano feel.

- Polyphony & Sampling Technology
- Virtual Resonance & Sound Processing
- Overall Sound Experience
Yamaha P-525: Premium Grand Piano Sound with Advanced Modeling
Piano Sound Engine
The P-525 uses Yamaha’s Pure CF Sound Engine, which includes samples from two world-class concert grand pianos:
- Yamaha CFX Grand – A bright, powerful, and clear grand piano tone used in concert halls worldwide.
- Bösendorfer Imperial Grand – A darker, richer, and more European-style grand piano sound with warm overtones.
Because of this dual-sampling system, the P-525 offers more tonal variety than the DGX-670, which only features the CFX grand piano sample. Players who enjoy both bright and warm piano tones will love this versatility.
Additional Sounds & Instrument Voices
While the P-525 is primarily a piano-focused instrument, it still offers a wide selection of additional instrument voices:
- 542 total voices, including electric pianos, organs, strings, choirs, harpsichords, guitars, and synths.
- 40 rhythm accompaniments to add simple backing beats for practice.
While this selection is much smaller than the DGX-670’s 630 voices, the P-525’s voices are higher-quality, sampled in greater depth, and feel more realistic—especially the electric pianos and organs.
Polyphony & Sampling Technology
- 256-note polyphony, allowing complex, sustained passages without note dropouts.
- Virtual Resonance Modeling (VRM), which simulates string resonance, damper resonance, and body resonance—essential for realistic sound.
- Binaural Sampling for Headphones, which enhances the CFX piano sound for a three-dimensional experience when using headphones.
VRM is a major advantage for the P-525, as it adds an extra layer of realism by modeling how sound resonates inside an acoustic piano cabinet.
Overall Sound Experience
Playing the P-525 feels incredibly rich, immersive, and natural. The Bösendorfer sample provides warmth for classical and jazz, while the CFX sample offers brilliance for pop and contemporary styles. VRM adds depth and sustain, making the P-525’s sound feel alive.

Yamaha DGX-670: Versatile Sound Engine with Hundreds of Instruments
Piano Sound Engine
The DGX-670 features Yamaha’s CFX Grand Piano Sample, which is an excellent, highly detailed grand piano sound. However, it lacks the Bösendorfer sample and VRM modeling found on the P-525.
This means that while the DGX-670 sounds great, it doesn’t fully capture the depth, resonance, and tonal complexity of the P-525. The sustain and string resonance effects are more limited, and subtle dynamics don’t translate as accurately.
However, for general piano playing and practice, the CFX sample on the DGX-670 is still excellent, and for many players, it will sound fantastic—especially for pop, rock, and casual playing.
Additional Sounds & Instrument Voices
One of the biggest advantages of the DGX-670 is its huge selection of additional instrument voices.
- 630 total voices, including pianos, electric pianos, orchestral instruments, brass, synths, guitars, and world sounds.
- 263 accompaniment styles, allowing full auto-accompaniment for pop, jazz, classical, and world music.
Unlike the P-525, which is designed as a stage/studio piano, the DGX-670 is an arranger keyboard with one-touch backing accompaniment, meaning you can play along with a full band or orchestra. This is ideal for songwriters, composers, and home musicians who want more than just piano sounds.
Polyphony & Sampling Technology
- 256-note polyphony, matching the P-525.
- No Virtual Resonance Modeling (VRM) – Resonance effects are present but not as detailed.

- Two 5 cm tweeters (enhancing clarity and high frequencies)
Compared to the DGX-670’s 12W speaker system, the P-525’s 40W output is significantly more powerful. This means it can:
- Fill larger rooms with sound without distortion
- Provide deeper bass and richer resonance
- Produce a more balanced frequency response from lows to highs
The 2-way speaker system ensures that different frequency ranges are handled separately—the larger speakers manage the bass and midrange, while the smaller tweeters handle treble frequencies. This results in a cleaner, more defined sound with better separation between notes.
Sound Projection & Clarity
One of the biggest strengths of the P-525’s speaker system is how well it projects sound.
- Even at low volumes, the bass remains present, and the highs remain crisp.
- At higher volumes, the sound does not distort, making it suitable for small gigs, church performances, or rehearsals without an external amp.
Additionally, the speakers are positioned for optimal projection, ensuring that the sound is not just directed downward but spreads outward. This results in a more immersive and natural listening experience, similar to how a real acoustic piano resonates in a room.
Bass Response & Frequency Range
The P-525 has a noticeably better bass response compared to the DGX-670. This is due to:
- Larger speakers that move more air, producing deeper bass.
- Stronger amplification, allowing for clearer, more pronounced low frequencies.

Beyond key action and sound quality, features and functionality play a major role in choosing a digital piano. Some players want a simple, piano-focused experience, while others prefer an instrument with arranger capabilities, learning tools, recording functions, and sound customization.
The Yamaha P-525 and Yamaha DGX-670 take very different approaches in this area:
- The P-525 is a performance-focused stage piano, prioritizing realistic sound, key feel, and essential digital enhancements.
- The DGX-670 is a versatile arranger-style digital piano, packed with backing styles, auto-accompaniment, and extra features for creativity and performance.
Let’s compare their functions in-depth to help you decide which one suits your needs best.
Built-in Voices & Instrument Selection
Yamaha P-525: Focused on High-Quality Acoustic and Electric Pianos

If you mainly play piano, jazz, or classical music, the P-525’s voice selection is perfect. However, if you want a huge variety of instrument sounds, the DGX-670 has more to offer.

However, compared to the DGX-670’s full arranger functions, the P-525 is very limited in this regard.
