Durock Piano vs. HMX SU

An in-depth look at the Durock Piano and the HMX SU switches—which one is the best fit for you?

Overview

When it comes to choosing the right linear mechanical keyboard switch, the Durock Piano and the HMX SU both offer unique characteristics that cater to different typing preferences. The Durock Piano is renowned for its delightful typing experience, characterized by a gliding push feel and a deep, creamy sound signature, thanks to its proprietary material blend. This switch is often described as 'bassy' and 'silky,' making it an excellent choice for users who appreciate a smoother, more refined auditory and tactile experience. On the other hand, the HMX SU, with its full PA12 housing and T5 stem, delivers a subtle yet relatively deep sound profile. While it might not have the same level of acoustic richness as the Durock Piano, it offers its own charm that could appeal to users seeking a straightforward yet satisfying typing experience. Both switches have their merits, depending on your personal preferences and typing style; however, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When comparing the housing materials of the Durock Piano and the HMX SU switches, we observe notable differences in the composition and characteristics of their top and bottom housings. The Durock Piano employs a proprietary POM blend for both its top and bottom housings, which is known for delivering a uniquely satisfying and deep sound profile, although the exact details of this blend remain unspecified. In contrast, the HMX SU relies on classic nylon for both its top and bottom housings, a material recognized for its ability to produce a deeper and fuller sound due to its softer composition. While both switches aim to provide a rich auditory experience, the POM blend of the Piano is likely to offer a slightly different resonance compared to the warmer, rounder tones associated with the nylon used in the SU.

The impact of these materials extends to the overall feel and sound produced by each switch when actuated. The Durock Piano’s POM blend, given its harder composition, may produce a more crisp and articulate sound during key releases, while its bottom housing contributes to a pronounced bottom-out sound. Conversely, the HMX SU’s nylon material contributes to a dampened sound profile, with its softer nature absorbing vibrations that result in a more muted auditory experience. This contrast highlights how the choice of housing materials influences user experience, with the Piano likely delivering a sharper auditory response and the SU providing a smoother, more subdued sound.

Despite the distinct characteristics of their housing materials, both the Durock Piano and HMX SU switches share the potential for producing enjoyable auditory experiences. The Piano, with its proprietary POM blend, and the SU, with its nylon housing, both aim to create a deep sound profile that enhances typing pleasure. Since each switch's performance is influenced by the combined effects of its top and bottom housings, it can be expected that, while they may sound and feel different in practice, users of both switches can achieve satisfying results by leveraging the unique properties of the respective materials utilized in each design.

Weight

When comparing the Durock Piano linear switch and the HMX SU linear switch, there are notable differences in both actuation and bottom out forces. The Durock Piano switch has an actuation force listed as None grams, which may imply a lack of representation in this metric, while its bottom out force is measured at 63.5 grams, indicating a medium-heavy feel when bottoming out. In contrast, the HMX SU linear switch features a defined actuation force of 45 grams, making it lighter and easier to press, while its bottom out force is 50 grams, which is also lighter than the Durock Piano. Consequently, for those who prefer a lighter typing experience that allows for prolonged use, the HMX SU would be the preferable choice. Meanwhile, the Durock Piano switch, with its heavier bottom out force, might appeal to users who favor a more substantial typing feel. Ultimately, users looking for a balance between ease of actuation and tactile feedback may need to consider their typing preferences when choosing between these two switches.

Travel distance

The travel distance of the Durock Piano linear switch is 4 mm, while the HMX SU linear switch has a travel distance of 3.6 mm. This makes the Piano switch the longer option, providing a more substantial depth that some users may find more comfortable and satisfying while typing or gaming. In contrast, the shorter 3.6 mm travel distance of the SU switch may appeal to gamers or individuals who prioritize a quicker response time and a more rapid actuation, albeit potentially at the expense of a more pronounced feel. If you're looking for a balance between depth and responsiveness, you might find that both switches provide satisfying results, but it ultimately comes down to personal preference regarding travel distance.

Typing experience

When it comes to sound, the Durock Piano switches are characterized by a rich, deep, and creamy tone that enhances the typing experience. This pleasant sound signature is further amplified by the unique material blend used in the switch, resulting in a gliding push feel that many find enjoyable. In contrast, the HMX SU switches are recognized for their subtle yet relatively deep sound profile attributed to their PA12 housing and T5 stem. While the SU may not be as explicitly detailed in terms of sound attributes, it also presents a pleasing auditory experience. Overall, while the Pianos offer a more defined bassy tone, both switches could deliver similarly satisfying acoustic profiles when combined with the right keyboard and keycaps.

In terms of feel, the Durock Piano switches shine with their silky smoothness, providing an exceptionally smooth typing experience that minimizes any resistance when pressing or releasing keys. This feature aims to maximize comfort during extended typing sessions. Meanwhile, the HMX SU switches lack specific descriptions regarding their feel, leaving a gap in comparative analysis. However, the absence of negative feedback may suggest they are also designed for comfort, possibly offering a smooth experience akin to the Pianos, depending on their build quality and design.

In conclusion, both the Durock Piano and HMX SU linear switches cater to enthusiasts seeking high-quality typing experiences. The Pianos excel with their rich, bassy sound and silky smooth feel, making them a favorite among users prioritizing auditory and tactile satisfaction. The SU switches, while less described, promise a similarly pleasant sound profile and likely contribute to a comfortable typing feel. Overall, your choice may hinge on personal preference for sound characteristics, but either switch has the potential to deliver an exceptional mechanical keyboard experience.

Conclusion

To conclude, choosing between the Durock Piano linear switch and the HMX SU linear switch depends largely on your typing preferences and intended use. If you enjoy a medium-heavy bottom-out force with a satisfying and creamy auditory feedback, the Durock Piano is the ideal choice for you. Its silky smoothness and deep, bassy sound make it perfect for long typing sessions where comfort and acoustics are paramount. This switch is particularly well-suited for users who appreciate a more robust tactile experience or those who spend a lot of time writing or gaming, as the deeper sound and feel can enhance the overall enjoyment.

On the other hand, if you prefer a lighter typing experience with quicker actuation, the HMX SU linear switch would be more appropriate. With a bottom-out force of just 50 grams, it allows for swift key presses, making it an excellent choice for fast typists or gamers who need rapid response times. Moreover, the SU's full PA12 housing contributes to a soft, subtle sound profile that may be more pleasing in quieter environments where a less pronounced acoustic footprint is desired.

Ultimately, your decision should factor in both your sensory preferences and the activities you'll be using your keyboard for. Whichever switch you choose, you can rest assured that both the Durock Piano and HMX SU linear switches offer their unique enhancements to your keystroke experience.
