Improved sound quality with titanium alloy bolts
Improved sound quality with lightweight and high rigidity
Sound quality benefits brought out by high-strength titanium alloy. Light weight and high rigidity to minimize the effects of vibration
BT-1 is a titanium alloy bolt and nut set that improves sound quality when securing the cartridge to the headshell. The vibration of the cartridge that picks up the unevenness of the record has a large effect, and the material of the fixing screw also has a large effect on the sound.
Acoustic benefits of titanium alloy
- Light weight and high strength: The material is titanium alloy. Although its specific gravity is 4.5, about half that of brass, it is so hard that it rivals steel in terms of strength.
- Superior speed of sound: Generally speaking, it is said that the speed of sound transmitted through a material (velocity of sound) is faster if the material is lighter and stronger. Titanium alloy satisfies this condition and has been proven to have great benefits in terms of sound quality.
- Recruitment results: Its excellent acoustic properties are also supported by its use in acoustic fields such as horn driver diaphragms.
- Sound quality trends: Hard materials tend to produce a hard sound, but titanium alloy's light weight and high rigidity make it an excellent cartridge set screw.
Custom made small brass nut
- Nut material: A gold-plated brass nut is included for fixing.
- Custom size: This nut is a custom-manufactured type with small external dimensions.
Compatibility: M2.6 with a small diameter of 4.0mm across, allowing it to fit easily into most cartridge mounts.

Improved response due to lightweight and high rigidity
The BT-1 is a cartridge mounting bolt that leverages the lightness and high rigidity of titanium, and is noted for its characteristic of faster sound response. Compared to typical brass or stainless steel bolts, the attack feels more agile, and the sound onset is perceived as clearer.
Resolution and Clarity
After replacement, the contours of the sound image become more defined, making it easier to grasp fine sound movements. The texture of the high frequencies becomes more precise, and by reducing unnecessary blur, the overall clarity improves. Rather than expanding the soundstage, it organizes the information, resulting in a clean and clear playback.
Sound Character: Cool and Neutral
As a characteristic of titanium's sound, it does not add excessive thickness or warmth, acting in a generally cool and neutral direction. The low frequencies are not emphasized in volume but gain more defined contours and a sense of speed. It is said to pair well with cartridges and systems that prioritize resolution.
Contribution to Setup Precision
The highly precise bolts offer stability during installation, enhancing the integration between the cartridge and head shell. They are less prone to looseness, and reproducibility after fine adjustments is excellent, making them valued as an easy-to-handle accessory during the tuning process.
The BT-1 is a titanium bolt set suitable for systems that emphasize sound speed and resolution. It can enhance sound clarity and detail without significantly altering the tonal character, making it an effective choice as a setup accessory to bring out the original performance of the cartridge.
