Yamamoto Sound Craft Titanium bolt set for BT-1 cartridge mounting

The material is light and strong with titanium alloy, and when used to stop the cartridge, it has the effect of improving sound quality. Since the cartridge picks up the unevenness of the record board as a music signal, the influence of the vibration appears greatly. Of course, the effect on the sound quality of the head shell is large, but the screw that fixes the cartridge also greatly affects the sound. The soft material is soft and the hard material seems to sound hard. Titanium alloy has a specific gravity of 4.5 and about half such as brass, and its strength is so hard that it does not pull on steel, and in the acoustic direction it is also used for the vibration plate of the horn driver, so the merit of the sound quality surface is large. In general, the speed of sound transmitted to the material is said to be as fast as light and durable material. These conditions prove that titanium alloy is excellent as a cartridge stop screw.
It comes with a brass gold plated nut as a fixed nut, but this nut is made custom-made with a small external dimension. Therefore, even when used on the cartridge side, it fits easily with most cartridge mounting parts. The nut is M2.6 and the opposite side is 4.0mm.
