1. Feed-back of PP-1000 magnetic circuit technology
To the magnetic circuit structure the technology of PP-1000, the flagship model, is applied; and by refining materials and manufacturing and finishing cost advantage has been enhanced. Furthermore, by changing to samarium-cobalt magnet, the recreation of excellent feeling of sound field and freshness has been successfully realized, which has been difficult for our conventional P-3.
2. Inheriting the Body for High Quality Audio Sound
We inherit duralumin previously-well-acknowledged against P-3 as the materials of base and body. Furthermore, DLC (Diamond Like Carbon) *1) coating is conducted; thereby, the structure excellent at rigidity and vibration-damping characteristics is realized.
*1) DLC (Diamond Like Carbon） is a generic name of 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.
3. Inheriting the Materials for High Quality Audio Sound
We inherit the following materials for high quality audio sound well-established in PP-1000 and others: Cantilever made of pure boron material well-acknowledged previously, magneto coil made of 6N oxygen-free copper wire, pure iron coil bobbin and others.
