HMX Blue Topaz vs. Durock Lupine
An in-depth look at the HMX Blue Topaz and the Durock Lupine switches—which one is the best fit for you?
Overview
When it comes to choosing between the HMX Blue Topaz and the Durock Lupine mechanical keyboard switches, both linear in design, there are distinct qualities that set them apart. The Blue Topaz is favored for its super smooth actuation and lightweight feel, making typing a breeze with a clacky sound signature that adds to the overall experience. On the other hand, the Lupine is praised for its two-stage long springs that provide a unique weight distribution and powerful rebound, along with a classic clacky sound profile. While the Blue Topaz offers an easy-to-press experience, the Lupine presents a more neutral and polished typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX Blue Topaz and the Durock Lupine share many similarities in terms of sound profile and aesthetic qualities. Both switches utilize polycarbonate for their top housing, resulting in sharper, higher-pitched, and crisper sound profiles. This is due to polycarbonate's stiffness, which produces a clear and resonant sound. Additionally, the translucent nature of polycarbonate makes it ideal for switches with RGB lighting, enhancing the overall visual appeal of the keyboard.
However, where the two switches differ is in their choice of bottom housing material. The Blue Topaz features a nylon bottom housing, which is known for producing a deeper and fuller sound profile. Nylon is softer than polycarbonate, absorbing more sound and creating a duller and rounder sound. In comparison, the Lupine also uses nylon for its bottom housing, resulting in a similar deep and full sound profile. This showcases how the bottom housing material can significantly impact the typing experience and overall sound of the switch.
In conclusion, while the top housing material of the HMX Blue Topaz and the Durock Lupine may be the same, their differing bottom housing materials provide unique typing experiences. The split between the qualities of the two housing materials results in a balance between the impact on bottom-out sound and feel. Whether it be the sharper sound of polycarbonate or the deeper sound of nylon, both switches offer a distinct typing experience that caters to different preferences in sound and feel.
Weight
When comparing the actuation force and bottom out force of the HMX Blue Topaz linear switch and the Durock Lupine linear switch, we can see some noticeable differences. The Blue Topaz has a lighter actuation force of 40 grams, making it easier to trigger keystrokes compared to the Lupine, which has an unknown actuation force. In terms of bottom out force, the Blue Topaz requires 48 grams to fully press down, while the Lupine bottoms out at a heavier 62 grams. The Blue Topaz is better suited for those who prefer a lighter touch for extended typing or gaming sessions, while the Lupine provides a more substantial typing experience for those who prefer a stronger push feel. In general, the Blue Topaz is lighter overall in terms of actuation and bottom out force compared to the Lupine.
Travel distance
The travel distance of the HMX Blue Topaz linear switch is 3.9 mm, while the Durock Lupine linear switch has a slightly shorter travel distance of 3.7 mm. Both switches fall within the range of shorter travel distances, which are becoming increasingly popular for their quick responsiveness, especially among gamers. However, the slight difference in travel distance may be noticeable to some users. The Blue Topaz offers a bit more depth with its 3.9 mm travel distance, which can provide a more satisfying typing experience for those who prefer a slightly longer press. On the other hand, the Lupine's 3.7 mm travel distance may feel more abrupt and snappy, appealing to users who prioritize speed and agility in their keystrokes. Ultimately, the choice between these two switches will come down to personal preference and typing style.

Moving on to feel, the Blue Topaz linear switch is known for its easy-to-press nature, offering gentle resistance during key presses and requiring minimal force to activate. This light actuation force makes typing effortless, comfortable, and reduces finger fatigue during long typing sessions. In contrast, the Durock Lupine linear switch offers a mild and polished typing experience, providing a gentle and approachable feel that falls within a safe middle ground. The polished finish of the Lupine switch results in smooth key travel and reduced friction while typing.
When considering all the available information, both the Blue Topaz and Lupine linear switches offer unique qualities in terms of sound and feel. The Blue Topaz provides a clacky sound with lightweight and smooth actuation, while the Lupine offers a neutral sound with a two-stage long spring for consistent weight distribution. Ultimately, the decision between the two switches will come down to personal preference in sound profile and typing experience. If you prefer a more distinctive and sharp sound with easy actuation, the Blue Topaz may be the better choice. However, if you prefer a more versatile sound profile with a gentle and polished typing feel, the Durock Lupine could be the ideal option. Regardless of choice, both switches are sure to provide a satisfying typing experience.
