Yamaha has crafted both the YDP-105 and YDP-S35 with different user needs in mind, offering two distinct designs that cater to different spaces, lifestyles, and personal preferences. While both pianos belong to the Arius series and maintain Yamaha’s commitment to high-quality craftsmanship, their form factors and build considerations set them apart.
Build Quality and Materials
One of Yamaha’s strengths in digital pianos is their attention to detail in build quality. Both the YDP-105 and YDP-S35 feature wooden cabinet-style enclosures, giving them the appearance of an acoustic piano rather than a typical keyboard-style digital piano. Yamaha uses high-quality MDF (Medium-Density Fiberboard) for both models, which offers durability while maintaining a relatively lightweight profile compared to solid wood.
- YDP-105: The YDP-105 follows a traditional upright digital piano design, with a robust structure that gives it a solid and classic look. The side panels are thick, reinforcing the sturdy frame, making it a reliable choice for home use. Its textured finish gives it a premium feel, ensuring it blends well with classic or contemporary home interiors.
- YDP-S35: The YDP-S35, in contrast, is built with a modern, slimline design aimed at users who prioritize space-saving aesthetics. Despite being thinner and more compact, the materials are still high-quality MDF, ensuring a stable and well-constructed frame. The sleek finish and minimalist design make it an excellent choice for small apartments, studios, or contemporary spaces.
Dimensions: Space Considerations
The difference in design philosophy is most evident in the dimensions of these two digital pianos.
| Feature | Yamaha YDP-105 | Yamaha YDP-S35 |
|---|---|---|
| Width | 53.42 in (135.7 cm) | 53.25 in (135.3 cm) |
| Height | 32.08 in (81.5 cm) | 31.19 in (79.2 cm) |
| Depth | 16.61 in (42.2 cm) | 11.63 in (29.5 cm) |
| Weight | 82 lbs (37.2 kg) | 81.5 lbs (37 kg) |
What These Dimensions Mean for You
- The YDP-105 is significantly deeper (16.61 inches vs. 11.63 inches), meaning it requires more floor space. If you have a dedicated music room or a larger living area, this might not be an issue. However, if you have limited space, this extra depth can make a difference in ease of placement.
- The YDP-S35’s slim profile makes it more versatile for smaller apartments, dorm rooms, or multifunctional spaces. The 5-inch reduction in depth allows it to fit comfortably against walls, in corners, or even in spaces where a larger digital piano might feel intrusive.
- Both models have a similar height and width, meaning they occupy roughly the same horizontal space. However, the YDP-S35’s lower profile gives it a sleeker, more modern aesthetic.
Key Cover Mechanism: Traditional vs. Compact Style
Both models come with a built-in key cover to protect the keys from dust and debris, but they differ in design and function:

Keyboard Action
The keyboard action is one of the most critical aspects of a digital piano, as it directly affects playability, technique development, and overall musical expression. Both the Yamaha YDP-105 and YDP-S35 feature Yamaha’s Graded Hammer Standard (GHS) action, a tried-and-true weighted key system designed to replicate the feel of an acoustic piano. However, despite having the same action mechanism, subtle differences in key response, touch sensitivity, and overall playing experience may influence a pianist’s choice.
The Graded Hammer Standard (GHS) Action
Both the YDP-105 and YDP-S35 use Yamaha’s Graded Hammer Standard (GHS) action, which is an entry-level weighted key system found in many of Yamaha’s digital pianos. The key weighting is designed to mimic the behavior of an acoustic piano, where the lower keys feel heavier and the higher keys feel lighter. This graduated weighting allows for a more realistic playing experience, especially for beginners and intermediate players transitioning to an acoustic instrument.
How GHS Compares to Other Yamaha Actions
Yamaha offers several key actions across their digital piano lineup:
| Key Action Type | Found In | Key Features |
|---|---|---|
| Graded Hammer Standard (GHS) | YDP-105, YDP-S35, P-125 | Entry-level weighted action, lighter key response, ideal for beginners |
| Graded Hammer 3 (GH3) | YDP-165, Clavinova CLP-725 | Triple-sensor system, improved responsiveness, more realistic touch |
| Natural Wood X (NWX) | Clavinova CLP-745+ | Wooden keys, superior weight distribution, highly realistic feel |
| GrandTouch-S / GrandTouch | Clavinova CLP-775+ | Flagship action, mimics grand piano responsiveness |
Since the GHS action is Yamaha’s entry-level weighted key system, it does not have some advanced features found in higher-end models, such as escapement simulation or triple-sensor technology. However, it is still a solid option for learning proper finger technique and dynamic control.
Key Weighting and Resistance: How Do They Feel?
While both the YDP-105 and YDP-S35 share the same GHS action, there are some minor differences in perceived key resistance due to structural design and materials.
- YDP-105: Since this model has a slightly deeper cabinet, it feels a bit more stable when playing aggressively. The GHS action has a moderate weight resistance, making it comfortable for beginners and intermediate players but slightly light for advanced pianists accustomed to grand pianos.
- YDP-S35: Because of its slimmer cabinet design, some users report that the action feels marginally lighter compared to the YDP-105. This might be due to the different internal structures supporting the keybed. The difference is subtle but could be noticeable for more experienced players.
Overall, both pianos offer the same graded weighting, but the YDP-105’s traditional structure may provide a slightly firmer playing surface.
Touch Sensitivity: Expressive Playing and Dynamic Control
Touch sensitivity refers to how the piano responds to variations in finger pressure, allowing for dynamic expression. Both the YDP-105 and YDP-S35 offer four levels of touch sensitivity:
- Soft – Ideal for light playing, requires less pressure for loud sound.
- Medium (Default) – Balanced touch response, similar to most acoustic pianos.
- Hard – Requires more pressure to achieve louder volumes, great for expressive players.
- Fixed – No touch sensitivity; all notes play at the same volume regardless of pressure.
Performance Notes:
- Beginners may prefer the Soft setting to ease finger strain.
- Intermediate and advanced players will benefit from the Medium or Hard setting, which allows for greater control over dynamics and expressive phrasing.
Both models have identical touch sensitivity settings, meaning that they provide the same level of dynamic control. However, due to the YDP-S35’s slightly lighter perceived action, players may feel a marginally quicker response when executing fast passages.
Key Material and Texture: Grip and Comfort
The material and surface texture of the keys significantly impact playability, particularly during extended practice sessions.
- Both models feature plastic keys rather than the synthetic ivory or wooden keys found in higher-end digital pianos.
- The black keys have a matte finish, providing a non-slip surface that enhances grip and control, reducing finger slippage.
- The white keys are smooth and glossy, which some players may find a bit slippery compared to synthetic ivory finishes.
While plastic keys are standard for this price range, some players transitioning from acoustic pianos may notice a difference in texture. For those who prefer a more traditional feel, Yamaha’s GH3 or NWX key actions (available in more expensive models) provide a closer experience to an acoustic grand piano.
Durability and Long-Term Performance
Since digital pianos rely on spring-loaded mechanisms rather than actual hammers and strings, the longevity of the key action is a major concern for serious players.
- Yamaha’s GHS action is known for its reliability and has been used in many models for over a decade.
- Both the YDP-105 and YDP-S35 have similar keybed construction, meaning they offer comparable durability.
- Over time, GHS keys may develop slight looseness or noise, especially after extensive use. However, this is common for entry-level weighted actions and is not exclusive to these models.
For users planning on intensive daily practice, a higher-end Yamaha action (such as GH3 or GrandTouch) may provide better longevity. However, for casual to moderate use, both the YDP-105 and YDP-S35 should last for many years.
Suitability for Different Playing Styles and Skill Levels
While both pianos offer a similar playing experience, certain types of players may find one model better suited to their needs.
Ideal Users for the Yamaha YDP-105:
✅ Beginners looking for a budget-friendly digital piano with a realistic key feel.

Sound Quality
Sound quality is one of the most crucial factors when choosing a digital piano. A well-sampled and resonant piano tone can greatly enhance the playing experience, providing both realism and expressiveness. Both the Yamaha YDP-105 and YDP-S35 are designed to replicate the sound of an acoustic piano, but they differ in terms of sound engine, polyphony, resonance, and overall tonal quality.
Sound Engine: AWM vs. Yamaha CFX Sampling
Yamaha YDP-105: Advanced Wave Memory (AWM) Sampling
The Yamaha YDP-105 uses Advanced Wave Memory (AWM) stereo sampling, a technology that has been around for quite some time in Yamaha’s digital pianos. AWM sampling captures and reproduces the tonal characteristics of an acoustic piano by using recorded samples rather than synthesized waveforms.
- How It Works: AWM records real acoustic piano sounds at different dynamic levels (soft, medium, and loud). These recordings are then played back based on the velocity at which the keys are pressed.
- Strengths: The AWM engine delivers clear and warm tones, particularly in the mid-range, making it suitable for beginners and casual players.
- Weaknesses: AWM is an older technology that lacks advanced resonance modeling, making the sound slightly less rich compared to Yamaha’s more modern sampling techniques.
Yamaha YDP-S35: Yamaha CFX Concert Grand Sampling
The YDP-S35, on the other hand, features Yamaha’s CFX concert grand piano sampling, which is a higher-quality and more advanced sound engine. The Yamaha CFX is Yamaha’s flagship concert grand piano, used in professional concert halls worldwide. By incorporating CFX sampling, the YDP-S35 delivers a more expressive and realistic piano tone.
- How It Works: The CFX sampling process records a wider dynamic range, capturing the nuances of soft pianissimo to powerful fortissimo playing.
- Strengths: The CFX engine produces a brighter, clearer, and more expressive tone with richer overtones than AWM sampling.
- Weaknesses: While the CFX sampling is superior to AWM, it is a “Lite” version (not the full CFX experience found in Yamaha’s Clavinova models).
Verdict: CFX Sampling is Superior
The Yamaha YDP-S35’s CFX sampling delivers a more detailed and expressive sound compared to the YDP-105’s AWM sampling. Players who appreciate rich harmonic overtones and dynamic depth will likely prefer the YDP-S35’s superior tonal clarity.
Polyphony: 64 Notes vs. 192 Notes
Polyphony refers to the maximum number of notes a digital piano can produce simultaneously. The higher the polyphony count, the more complex pieces can be played without notes cutting off prematurely.
- Yamaha YDP-105: 64-note polyphony
- Yamaha YDP-S35: 192-note polyphony
Why Does Polyphony Matter?
When playing fast classical music or using the sustain pedal, polyphony is crucial because many notes continue resonating even after being played. A low-polyphony piano may cut off sustained notes, making performances sound unnatural.
- 64-note polyphony (YDP-105) is sufficient for basic and intermediate playing, but can struggle with complex classical pieces like Rachmaninoff or Debussy, where sustained harmonies are essential.
- 192-note polyphony (YDP-S35) provides more than enough headroom, ensuring that every note rings out naturally, even with layered sounds or sustain pedal usage.
Verdict: YDP-S35’s Higher Polyphony Wins
For serious pianists or those planning to play complex compositions, the YDP-S35’s 192-note polyphony is a significant advantage over the YDP-105.

One of the biggest differences between the YDP-105 and YDP-S35 is their handling of resonance and acoustic realism.
- YDP-105: Does not include resonance modeling.
- YDP-S35: Features VRM Lite (Virtual Resonance Modeling Lite) technology.
What is VRM Lite?
Virtual Resonance Modeling (VRM) is Yamaha’s technology that simulates the sympathetic resonance of strings and the soundboard vibrations found in real acoustic pianos.
- When playing an acoustic piano, pressing the sustain pedal causes all the strings to vibrate sympathetically, creating rich overtones and resonance.
- In digital pianos, VRM Lite mimics this effect, adding depth, warmth, and realism to the sound.
Verdict: YDP-S35’s VRM Lite Makes a Noticeable Difference
Since the YDP-105 lacks resonance modeling, it sounds drier and less immersive, especially when using the sustain pedal. The YDP-S35’s VRM Lite feature helps replicate the organic resonances of a real piano, making it the better choice for those seeking authentic acoustic realism.
Final Verdict: Which Piano Sounds Better?

What This Means for You
- If you only need MIDI connectivity for learning apps (like Simply Piano or Flowkey), both models will work fine.
- If you plan to record high-quality audio directly to a computer, the YDP-S35 is the better choice because of its USB audio transmission.
- With the YDP-105, you will need an external audio interface to capture the piano’s sound, adding complexity to the recording process.
Verdict: The YDP-S35 Wins for Recording and Production
If you want a straightforward way to record high-quality audio, the YDP-S35’s USB audio support makes it the better option.
Headphone Jacks: Silent Practice for Two Players
| Feature | Yamaha YDP-105 | Yamaha YDP-S35 |
|---|---|---|
| Number of Headphone Jacks | 2 | 2 |
| Stereophonic Optimizer (Enhances Headphone Sound) | No | Yes |
How This Affects Silent Practice
- Both pianos feature dual headphone jacks, allowing two players to practice together quietly (great for teachers and students).
- The YDP-S35 includes Yamaha’s Stereophonic Optimizer, which enhances spatial depth when using headphones, making the sound feel more natural and less “inside your head.”
- The YDP-105 lacks this feature, meaning headphone users may experience a flatter, more artificial sound.
Verdict: YDP-S35 Provides a More Immersive Headphone Experience
If you practice frequently with headphones, the YDP-S35 offers a noticeably better sound balance.
Smart Pianist App: External Control and Learning Features
Both models support Yamaha’s Smart Pianist app, a powerful tool that allows you to:
🎵 Change instrument voices easily from a tablet or phone.
🎵 Adjust settings and effects like reverb and touch sensitivity.
🎵 Display sheet music and chord progressions for learning songs.

Verdict: Both Models Are Equal in Smart Pianist Integration
While Smart Pianist is a great feature, there is no difference between these two models in terms of app compatibility.
Lack of Bluetooth Connectivity: A Missed Opportunity?
One feature missing from both models is Bluetooth connectivity. Many modern digital pianos now support Bluetooth MIDI and Bluetooth Audio, allowing users to:
- Wirelessly connect to apps like GarageBand, Flowkey, and Simply Piano.
- Stream backing tracks through the piano’s speakers for play-along practice.
Alternatives for Wireless Connectivity
Since neither the YDP-105 nor YDP-S35 includes Bluetooth, you would need:
- A USB-to-Bluetooth MIDI adapter (such as the Yamaha UD-BT01).
- An external Bluetooth audio receiver if you want to stream music through the speakers.
Verdict: Both Models Lack Bluetooth, Which May Be a Dealbreaker for Some Users
If wireless connectivity is a priority, you may need to consider a different Yamaha model (such as the Yamaha P-515, which has built-in Bluetooth MIDI).
External Speaker and Audio Connectivity
Neither the YDP-105 nor YDP-S35 includes dedicated audio output jacks (such as RCA or 1/4″ line outs).
- If you want to connect external speakers or an amplifier, you will need to use:
