Materials Innovations: World's First Use of Stainless Steel 904L for DAP Body Material

To achieve the goal of the A&ultima series, which is 'to provide the best value that no one can imitate while using the most innovative and uncompromising design and craftsmanship, the SP3000 uses 904L stainless steel material that has never been attempted before in a portable audio player. Using this material has expanded its value from just a digital device to the realm of a luxury good.

904L stainless steel is harder and more difficult to process than general stainless steel requiring significantly more time and effort. However, due to its excellent durability and corrosion resistance, it has a characteristic that does not lose its beauty and this is why it is used in expensive luxury watches where perfection in all materials and parts must be pursued with an irreplaceable and wonderful lustre.

Experience the uncompromising beauty and luxury of the SP3000 produced by Astell&Kern’s experienced craftsmanship.
