Astell&Kern/A&ultima SP3000M Copper Nickel

Astell&Kern / A&ultima SP3000M Copper Nickel

The "A&ultima SP3000M Copper Nickel" is a special edition of the seventh model in the A&ultima series, the "SP3000M," which uses "nickel-nickel" as the housing material. This alloy is used in wind instruments and is known for producing a deep, full-bodied sound.

■Special edition with "nickel-nickel" housing material
・The A&ultima SP3000M Copper Nickel uses "nickel-nickel," an alloy of copper and nickel that is used in wind instruments and known for producing a deep, full sound, as the housing material. Nickel-nickel is known to be extremely difficult to process, and its beautiful luster and silver color seen in high-end jewelry and crafts add a sophisticated elegance to the design of the SP3000M. In addition to enhancing the presence of the product, the extremely high corrosion resistance characteristic of nickel-nickel ensures that its beauty lasts longer, and it also has high antibacterial properties. Furthermore, the excellent shielding performance boasts high conductivity and low magnetism, allowing you to experience a unique tone that is different from the original SP3000M, which has an aluminum housing. The exclusive premium real leather case that comes only with the A&ultima line also uses a special color that accentuates the beauty of the SP3000M Copper Nickel. By expressing the characteristics of the material itself and its unique beauty, it completes the identity and design value of Astell&Kern.

・Base model: A&ultima SP3000M
The A&ultima SP3000M is the seventh model in the A&ultima series, with the slogan "Compact Size, Limitless Sound," which maintains the outstanding sound performance of the flagship model SP3000 while being compact and lightweight. Normally, in order to improve audio performance, there are physical limitations and it is inevitable that the size will be increased. However, portability is also an important factor in portable audio. Astell&Kern faced the challenge of miniaturizing while maintaining the flagship sound performance head-on, and after adopting its own technology, dozens of prototypes, and the adoption of an aluminum housing, the SP3000M was completed and the goal was achieved. The SP3000M has been miniaturized by reviewing the board design, but it is equipped with an innovative "HEXA audio circuit structure" that completely separates digital signal processing and analog signal processing by using two premium digital data converters "AK4191EQ" and four AKM flagship DACs "AK4499EX" as the SP3000. It uses a dual audio circuit that completely separates unbalanced and balanced outputs without a switch. You can enjoy the changes in sound with a variety of functions such as software-controlled real-time upsampling DAR function, DAC filter function, and crossfeed function. You can also enjoy the changes visually with the VU meter function. With a 4.1-inch HD display and a high-performance Snapdragon 6125 Octa-core CPU, it achieves comfortable operability and sound performance despite its small size. In addition, the SP3000M, which is part of the A&ultima series, comes with a dedicated real leather case. The SP3000M is a true portable Hi-Fi audio player that has been miniaturized while inheriting the audio performance of the flagship.

■Special color premium leather case included
・The SP3000M Copper Nickel bundle case uses soft cowhide from GRUPPO MASTROTTO, which boasts excellent craftsmanship worthy of the A&ultima flagship line. This leather case, which features a soft touch, has a unique antibacterial treatment. Chrome tanning and dyeing with high-quality pigments give the leather surface a uniform texture and the vivid color characteristic of Italian leather. The back of the case features the same pattern as the SP3000M, creating a sense of unity. GRUPPO MASTROTTO is a leather manufacturer with over 60 years of tradition since the Mastrotto family founded "Conceria Mastrotto" in Arzignano, Italy in 1958. With over 2,200 employees worldwide, the company produces high-quality leather through 18 rigorous processes in 15 factories. It is one of the most prestigious groups in Italy in the leather industry.
