New design of a magnetic circuit
The technology of the flagship model PP-2000 is applied for this magnetic circuit structure. Therefore, just like PP-2000, we have achieved for this product to provide an excellent magnetic field having high efficiency and uniformity.
Consequently the output is increased without making the vibration system heavier.
Improving the trackability by readjusting the vibration system
In order to aim for the best balance of optimum sound quality in this class, we improved the PP-300’s vibration system, adopting the base made of duralumin and tuned this vibration system exclusively for PP-500.
Consequently it is achieved that the powerful sound quality and realistic sensation can be expressed.
Inheriting the high quality materials for audio sound
High quality materials for audio sound verified in PP-2000 and other models are inherited and they are well-acknowledged until now for the following parts: cantilever made of pure boron material, magneto coil made of 6N oxygen-free copper wire, pure iron coil bobbin, damper, and so forth.
For the body, the well-acknowledged DLC (Diamond Like Carbon) * coating has been adopted continuously.The unclouded sound quality being well suited for the rigidity and vibration-damping properties have been realized.
*DLC（Diamond Like Carbon）is a generic name of a carbon film to be produced with vapor phase synthesis utilizing ion processing and the high rigidity and high electric insulation similar to a diamond are provided for it.
