TY-1 Titanium finger hook

TY-1 is a finger rest for headshells. The body is made of lightweight and highly rigid pure titanium, with an O-ring made of silicone to prevent slipping.
The TY-1 is designed to improve sound quality by giving strength to the finger rest, which is usually made of aluminum or other thin and soft materials.
If your headshell uses M2 size screws, it can be installed without any problem.

By replacing the existing finger hook with a high-rigidity titanium round bar, the rigidity of the entire headshell is increased, which improves sound tightness and clarifies the sound image, whereas the existing finger hook had a slight shake during playback. The silicone O-ring attached to the tip of the head shell is also removable, allowing the user to enjoy the change in sound.

The TY-1 titanium finger hook is made of a hard material and is rod-shaped, so there is no concern about squeaking. After listening to a normal sound with the company's brass finger-hook, I switched to the TY-1. The sound image became more refined and tighter than I had expected. At the same time, I noticed a faint accent in the wide range of sound that accompanies the brass finger rests. It was a double surprise. If you are using a finger rest with M2 screws, you are in luck. I recommend you to "tune" your finger rest.
The effect of the non-slip silicone O-ring is also not insignificant. It is quiet when it is attached, and sounds open and resonant when it is removed. I chose to remove it.
