The Monument for Masterpiece 

SP3000 24K Gold Limited Edition
Based on its innovative technology and perfect design, the A&ultima SP3000 received the highest praise from audiophiles and media outlets worldwide, for ‘opening a new horizon with an overwhelming sound that reaches the pinnacle of digital audio players.’ Astell&Kern sought to commemorate the monumental success of the SP3000 by introducing the SP3000 24K Gold Limited Edition crafted with gold, the most valuable metal in human history.

Astell&Kern started with the innovative Stainless Steel 904L material used for the first time in the SP3000 and plated it with 24K pure gold to capture the pinnacle sound of the SP3000 in a metal of extreme luxury and value.
Gold has a beautiful luster, does not rust, and has excellent electrical conductivity, so it is used not only in jewellery, but also as a top-quality component for semiconductors and high-end audio, and is highly valued due to its rarity. However, the highest purity 24K gold is difficult to handle due to its low hardness, so extremely meticulous processes and work were required to complete the SP3000 24K Gold Limited Edition, which has a much larger area than jewellery, into a flawless product.
To deliver the highest quality product without compromise, Astell&Kern used a wet process for pure gold plating (plating thickness of 0.5um+/- 20%) rather than simply a surface treatment. To fully highlight the SUS 904L material and gold plating, nickel plating was first applied, followed by the 24K gold plating, and then an AF coating was applied to harden the surface and prevent fingerprints.

The SP3000 24K Gold Limited Edition is a monumental design that fully expresses Astell&Kern's brand philosophy.
Discover a new horizon for premium audio players with the unique beauty of timeless metals, and the amazing sound of the SP3000. The SP3000 24K Gold Limited Edition includes a special leather case and package exclusive to this limited edition.
