HMX Blue Topaz vs. SP-Star Duck
An in-depth look at the HMX Blue Topaz and the SP-Star Duck switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the HMX Blue Topaz and the SP-Star Duck offer unique experiences for users. The Blue Topaz is a linear switch that prides itself on its smooth actuation and light feel, making typing a breeze. With its distinctive glitter housing and clacky sound signature, it appeals to those who appreciate both aesthetics and auditory feedback.

Housing materials
When comparing the housing materials of the HMX Blue Topaz and the SP-Star Duck, it is evident that both switches utilize polycarbonate for their top housing. This material choice results in a sharper, higher-pitched, and crisper sound profile for both switches. The stiffer nature of polycarbonate lends itself to a more clear and resonant sound, making it an ideal choice for switches that prioritize sound quality. Additionally, the translucent nature of polycarbonate makes it perfect for switches designed with RGB lighting in mind. Therefore, in terms of top housing, both the Blue Topaz and the Duck offer similar results in sound profile and aesthetic appeal.
However, where the two switches differ is in their choice of bottom housing materials. The Blue Topaz utilizes a nylon bottom housing, which produces a deeper and fuller sound profile compared to the sharper sound profile of the polycarbonate top housing. The softer nature of nylon absorbs more sound, creating a duller and rounder sound that may appeal to those seeking a quieter typing experience. On the other hand, the Duck's polycarbonate bottom housing maintains the sharper, crisper sound profile associated with this material, offering a more consistent sound profile across the entire switch.
In conclusion, while both the HMX Blue Topaz and the SP-Star Duck feature polycarbonate top housings for a sharp and clear sound profile, their choice of bottom housing materials sets them apart. The Blue Topaz's nylon bottom housing provides a deeper and fuller sound profile, ideal for those looking for a quieter typing experience, while the Duck's polycarbonate bottom housing maintains the sharp and crisp sound profile associated with this material. Ultimately, the differences in bottom housing materials allow for unique typing experiences with each switch, catering to a variety of preferences in sound and feel.
Weight
The HMX Blue Topaz linear switch and the SP-Star Duck tactile switch have different characteristics in terms of actuation force and bottom out force. The Blue Topaz has a lighter actuation force of 40 grams compared to the Duck, which has an unknown actuation force. In terms of bottom out force, the Blue Topaz is also lighter at 48 grams, while the Duck is heavier at 58 grams. Those who prefer a lighter typing experience may lean towards the Blue Topaz, as it allows for longer typing sessions without fatigue. On the other hand, those who enjoy a more substantial typing experience may opt for the Duck due to its heavier bottom out force. Ultimately, the choice between the two switches will depend on individual preferences for typing feel and weight.
Travel distance
The travel distance of the HMX Blue Topaz linear switch is 3.9 mm, while the SP-Star Duck tactile switch has a travel distance of 4 mm. This means that the Duck has a slightly longer travel distance compared to the Blue Topaz. In general, a 4.0 mm travel distance is considered the most traditional, while a 3.0 mm travel distance is the most shallow. Gamers tend to prefer shorter travel distances for faster response times, making the Blue Topaz a popular choice for gaming. However, some users may find shorter travel distances to feel too abrupt, in which case the Duck's slightly longer travel distance may be more suitable. Ultimately, the choice between these two switches depends on personal preference for travel distance and desired typing experience.
