Overview For the arm pipe, a boron titanium pipe is used, in which a boron layer is formed on the surface of a lightweight metal titanium pipe with high mechanical strength and elastic modulus by a special forming method, and a boron diffusion layer is provided inside the pipe. This design emphasizes sound quality by increasing mechanical strength and suppressing harmful partial resonance such as bending and twisting.Boron aluminum, which is a composite refinement of aluminum and aluminum fiber, is used to achieve high rigidity and light weight. The tone arm uses a highly sensitive gimbal suspension bearing structure.A total of 20 ruby balls with an extremely small coefficient of friction (1/3 that of a wheel) are used for the horizontal and vertical bearings to achieve an extremely small initial sensitivity of 5mg. A unique variable dynamic damping braking system is used.In this method, the movable weight part in the balance weight is supported by a spring with high strength and damping effect, and the mass of the movable weight is divided using its compliance. In addition, the spring support is covered with a damping cylinder that contains silicon oil to enhance the braking (damping) effect of the spring support by viscous resistance. This dramatically improves the low-frequency resonance peak (sharpness Q). Furthermore, in consideration of the fact that the low-frequency resonance frequency varies depending on the compliance and weight of the cartridge used, a magnetic damping adjustment function is provided for more effective damping. This function is designed to change the resonance frequency of the movable weight section by changing the distance between the two magnets, thereby reducing the low-frequency resonance peak (sharpness Q), flattening the frequency response, and reducing the low-frequency mechanical impedance. This reduces the frequency response, and also reduces the low-frequency mechanical impedance, which in turn reduces the intermodulation distortion and ultra-low-frequency noise caused by record sledding, thus bringing out the performance of the cartridge and improving the tracing performance.In addition, high fidelity and high signal-to-noise ratio reproduction is possible, and the isolation performance from external vibrations is also improved. The arm height can be adjusted within a range of 20mm by using a precision 12-jaw helicoid structure made of zinc die-cast metal.
