MDF is too heavy and too dull for many applications. Additionally, you have to treat MDF with additional surfaces to make it visually attractive and domestically acceptable. Its composition is not always conducive to creating tiny structures, leading to a lack of precision in manufacturing.

"Yosegi" the traditional Japanese method of making objects with real value. A number of "micro-quadratic" pieces of various types of natural wood are glued together with special resins. It demands incredible, high-precision work abilities, the levels which are only available from the hands of long-trained, highly-skilled specialists.
Yosegi techniques are expensive, but capable of yielding exceptional beauty protected by extremely high durability. At the heart of the cartridge are selected motors, cantilevers and diamonds, of the calibre expected of the very best Japanese-made pick-ups. Thanks to the combination of traditional Yosegi woodworking art and modern high-end materials, the EAT Yosegi cartridge produces wonderfully smooth but vivid and open reproduction of the stored music.
