Housing materials
The housing materials of the HMX Blue Topaz and the Durock Piano exhibit distinct characteristics that affect the sound profile of the switches. The Blue Topaz utilizes a polycarbonate top housing, known for producing a sharper and crisper sound compared to the Piano's proprietary POM blend top housing. Polycarbonate's stiffness contributes to a clear and resonant sound, especially ideal for switches with RGB lighting. On the other hand, the POM blend in the Piano's top housing offers a uniquely satisfying and deep sound profile, although the exact details of the blend remain undisclosed.
In terms of the bottom housing materials, the Blue Topaz features a nylon bottom housing, which creates a deeper and fuller sound profile due to its softer nature that absorbs more sound. In contrast, the Piano's proprietary POM blend bottom housing also offers a satisfying and deep sound profile, mirroring the qualities found in the top housing. While the exact composition of the POM blend remains unknown, it is evident that both the Blue Topaz and the Piano prioritize sound quality in their design choices.
When considering the impact of different housing materials on the overall switch performance, it is important to note that the qualities of the top and bottom housing materials are divided between the two. The bottom housing affects the bottom-out sound and feel when you press down on the switch, while the top housing influences the sound when you release the key. This division allows for a more nuanced sound profile and tactile experience in switches like the Blue Topaz and the Durock Piano, enhancing the overall typing or gaming experience for users.
Weight
When comparing the actuation force and bottom out force of the HMX Blue Topaz linear switch and the Durock Piano linear switch, it is evident that they have significant differences. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, making it a lighter switch overall. On the other hand, the Piano switch has an unknown actuation force and a bottom out force of 63.5 grams, placing it in the medium-heavy category. Those who prefer a more substantial typing experience may opt for the Piano switch due to its heavier bottom out force, while individuals who value longer typing sessions may lean towards the lighter actuation force of the Blue Topaz. Both switches offer distinct advantages depending on the user's preference, with the Blue Topaz providing a lighter touch and the Piano offering a more tactile typing experience. Ultimately, the choice between the two switches will depend on the individual's typing style and preference for actuation and bottom out forces.
Travel distance
The travel distance of the HMX Blue Topaz linear switch is 3.9 mm, while the Durock Piano linear switch has a travel distance of 4 mm. This means that the Blue Topaz has a slightly shorter travel distance compared to the Piano. Both switches fall within the range of shorter travel distances, which are preferred by gamers for faster response times. However, some users may find the shorter travel distance of the Blue Topaz to be too abrupt, while others may appreciate the extra depth provided by the Piano. Ultimately, the choice between the two switches will depend on personal preference for travel distance.
