"Universal tone arm which adopted the world's first Boron Titanium pipe arm, boron aluminum head shell. The world's first Boron Titanium pipe with a boron diffusion layer formed inside by creating a boron layer on the surface of a metal Titanium which is lightweight and has a large mechanical strength and elastic modulus by special generation method is adopted as the arm pipe part doing. This increases mechanical strength and reduces harmful partial resonance such as bending and twisting and designs sound quality emphasis. In addition, we adopted boron aluminum which combined refining of boron fiber and aluminum for the head shell part, realizing high rigidity and weight reduction. For the tone arm, we adopt a high sensitivity gimbal suspension bearing structure. Rolyballs with extremely small coefficient of friction, about 1/3 of the wheel, are used for horizontal and vertical bearing bearings, totaling 20 stones, achieving a minimum initial sensitivity of 5 mg.
I adopt original brake variable variable dynamic damping method.
In this method, the movable weight part in the balance weight is supported by a spring with high strength and damping effect, and mass of the movable weight is divided by mass using its compliance. Furthermore, the spring support part is covered with a damping cylinder, silicon oil is built in it, and the effect of damping of the spring support part is enhanced by viscous drag. As a result, the low-frequency resonance peak (sharpness Q) has dramatically improved.
Furthermore, taking into consideration the fact that this low frequency resonance frequency varies depending on the compliance and weight of the cartridge to be used, in order to brush more effectively, the magnetic damping adjustment function is carried. This is a structure in which two magnets are provided in the movable weight portion and the resonance frequency of the movable weight portion is changed by changing the distance between the two magnets, whereby a low-frequency resonance peak (sharpness Q), reduce frequency impedance, reduce low-frequency mechanical impedance, reduce intermodulation distortion due to warping of records and ultra low-frequency noise to improve the performance of the cartridge and improve the trace performance I will.
In addition, it enables high fidelity, high SN ratio playback, and improves the blocking performance of external vibration.
The precision 12-degree helicoid structure zinc die casting arm height adjustment function is carried and the arm height can be adjusted within the range of 20 mm. "
I have this EPA-100 mkII tonearm, but i need to modify my luxman armboard to mount it, i'm looking forward.
Sold my original EPA-100 long time ago, so i can't compare them unfortunately.
