Design Concept

The SP1000 the first A&ultima player is like a natural gemstone carefully refined by professionals. Knowing that sound is reflected from mass like light is reflected from a surface; Astell & Kern designed the SP1000 like a gemstone with reflective features on its surface. The crown-patterned volume wheel on the right corner is similar in appearance to a cut gemstone which reflects light from various angles. The sophisticated volume wheel on SP1000 not only delivers visual and textual details with precision but allows convenient one finger ON/OFF control and fine volume control with the addition of both push and turn features. The external chassis of the SP1000 is made of rugged stainless steel that resists aging and external shock. The SP1000 is the ultimate music player crafted in an artistically designed metallic setting.
