KTT Ash Gray vs. HMX SU
An in-depth look at the KTT Ash Gray and the HMX SU switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, personal preference plays a crucial role, and two switches that often come up for comparison are the KTT Ash Gray and the HMX SU. The KTT Ash Gray, a tactile switch, is celebrated for its ability to deliver a substantial yet unobtrusive tactile response, making it an excellent choice for typists looking for that satisfying feedback without being too overwhelming. Users can expect a light touch paired with a crisp actuation that strikes a perfect balance between tactile sensation and typing comfort. On the other hand, the HMX SU is a linear switch known for its smooth actuation and relatively deep sound profile, thanks to its full PA12 housing and T5 stem. This switch caters to gamers and those who prefer a quieter typing experience, allowing for rapid key presses without the distractions of tactile pressure points. Both switches provide distinct advantages: the Ash Gray for its tactile feedback and typing accuracy, and the SU for its seamless and silent performance. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The KTT Ash Gray and the HMX SU switches showcase distinct differences in their top housing materials which significantly influence their sound profiles. The Ash Gray features a polycarbonate top housing, known for its stiffness and translucency. This material creates a sharper, higher-pitched, and crisper sound profile, which can be enhanced further when incorporating RGB lighting, as the clear housing allows the lights to shine through more effectively. In contrast, the HMX SU uses a nylon top housing, a material that is softer and more sound-absorbent. Consequently, the nylon housing produces a deeper, fuller, and comparatively duller sound. This fundamental difference in material not only affects the auditory experience when typing but also highlights distinct aesthetic capabilities, especially regarding backlighting.
When it comes to the bottom housing, both the KTT Ash Gray and HMX SU switches utilize nylon. This commonality means that regardless of the differences in their top housings, the bottom housing contributes significantly to the overall typing sound and feel. Since nylon is a softer plastic, it creates that rich, full sound characteristic that typists might favor. This shared feature implies that the bottom-out sound and tactile feedback during operation will be similar when using both switches, as both will absorb sound in a comparable manner and produce deep resonating sounds.
The interplay between the differing top and uniform bottom housings in these switches exemplifies how contrasting materials can influence a switch's final acoustic effect. With the KTT Ash Gray’s polycarbonate top housing leading to a crisper sound, combined with a fuller bottom from the nylon, it offers a balanced auditory profile with brighter notes. Meanwhile, the HMX SU with its all-nylon construction provides a more homogenous deep sound. Thus, while the Ash Gray's dual-material construction allows for a more layered sound experience, both switches share a common foundation in their bottom housing, resulting in similar deep tones despite their differences in sharpness and clarity.
Weight
The KTT Ash Gray tactile switch and the HMX SU linear switch exhibit notable differences in their actuation and bottom out forces. The Ash Gray has an actuation force of 38 grams and a bottom out force of 53 grams, making it a medium-light option that caters well to typists looking for a lighter touch. In contrast, the HMX SU switch has an actuation force of 45 grams, which is heavier than the Ash Gray, while its bottom out force is slightly lighter at 50 grams. As such, the SU switch may appeal to those who prefer a stronger, more substantial typing experience, albeit it does provide a lighter bottom out force. Overall, the KTT Ash Gray is the lighter of the two switches, while the HMX SU is heavier in terms of actuation force, resulting in different tactile experiences suited to users' preferences.
Travel distance
When comparing the travel distances of the KTT Ash Gray tactile switch and the HMX SU linear switch, the Ash Gray measures 3.5 mm, while the SU has a slightly longer travel distance of 3.6 mm. This makes the Ash Gray the shorter option between the two, offering a more responsive feel that may appeal to gamers who favor quicker actuation times. Conversely, the HMX SU, with its longer 3.6 mm travel distance, might provide a more substantial keystroke that some users prefer for a deeper tactile experience. While both switches fall within the realm of shorter travel distances compared to traditional switches, the Ash Gray offers a more immediate response, whereas the SU allows for a more deliberate press.

Typing experience
When it comes to sound, the KTT Ash Gray tactile switch presents a neutral profile, yielding a moderate actuation force and a sound that can comfortably fit both home and office environments. This versatility makes the Ash Gray ideal for users who want a reliable switch without drawing too much attention. While the sound of the HMX SU linear switch is undisclosed, it is noted to have a relatively deep sound profile due to its PA12 housing and T5 stem, suggesting a weightier auditory characteristic that may contrast with the Ash Gray's more balanced output. However, it is essential to recognize that the overall sound profile of both switches can be significantly influenced by factors such as the keyboard board and the keycaps used.
In terms of tactile feel, the Ash Gray switch excels with its easy-to-press mechanism, providing gentle resistance that requires minimal force to activate. This encourages comfort during extended typing sessions, decreasing finger fatigue while ensuring a pleasant typing experience. The switch's mild tactile feedback strikes a balance perfect for users desiring an approachable typing feel without overwhelming sensations or harshness. Data on the feel of the HMX SU linear switch is not provided, leaving an unknown in this area, but it can typically be expected that a linear switch will lack any tactile bump, focusing instead on a smooth keystroke.
In conclusion, both the KTT Ash Gray and HMX SU switches offer unique qualities that cater to different preferences. The Ash Gray shines with its neutral sound profile and comfortable tactile feedback, making it a solid choice for versatile use. In contrast, while the HMX SU presents potentially distinct sound characteristics, its feel remains unspecified, meaning users should consider their preferences when selecting. Whether for home, work, or gaming, the Ash Gray delivers an inviting typing experience, while the SU may serve those favoring smoother linear input. Ultimately, both switches can meet a variety of user needs, depending upon the use case and desired outcomes in terms of sound and feel.
Conclusion
To conclude, choosing between the KTT Ash Gray tactile switch and the HMX SU linear switch ultimately depends on your personal preferences and intended use. If you appreciate a medium-light tactile experience that provides a pleasant balance of tactile feedback and ease of actuation, the Ash Gray is an excellent choice. Its neutral sound profile makes it suitable for both quiet environments, like an office, and more casual settings at home. The mild nature of the Ash Gray ensures that you won’t get overwhelmed by feedback, making it ideal for long typing sessions without causing finger fatigue. On the other hand, if you prefer a lighter switch that offers smooth key presses without any tactile bump, the HMX SU linear switch may be more to your liking. Its subtle and relatively deep sound profile adds a unique auditory experience, which might cater better to those who enjoy a simpler, uninterrupted keystroke feel. In essence, the Ash Gray is for those who like tactile feedback and a bit of resistance, while the SU is perfect for those seeking a quieter, streamlined typing experience. Your choice should resonate with your typing style and the contexts in which you intend to use the keyboard.
