Get Both High Output
and Vivid Sound
Traditional audio has suffered from noise and distortion as power output is increased.
Astell&Kern’s advanced audio design and signal management technologies used in the A&ultima
SP1000 brings more power output with less noise and minimal distortion.
Independent DACs for the left and right audio channels provide a wider soundstage and better stereo separation. Each AK4497EQ DAC provides rich and vivid audio reproduction, allowing the listener to enjoy the sound as it was meant to be heard.

The A&ultima SP1000 is like a natural gemstone carefully refined by professionals.
Knowing that sound is reflected from mass, like light is reflected from a surface;
we designed the A&ultima 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 A&ultima 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 A&ultima SP1000 is made of rugged Stainless Steel/Copper that resists aging and external shock. The A&ultima SP1000 is the ultimate music player, crafted in an artistically designed metallic setting.
Introducing the new SP1000 Onyx Black. This sleek and premium black coated stainless steel was made possible using PVD (Physical Vapor Deposition) coating technology. It is environmentally friendly and the results are finishes that provide long-lasting protection and durability, are resistant to chemicals, easy to maintain and protect against corrosion and wear. PVD coating has been used for products where higher endurance and reliability is demanded, including medical instruments, luxury accessories and more.
