      Brimming with the latest technologies and meticulously crafted, the A&ultima SP1000 digital audio player takes its place at the top of Astell & Kern's high-resolution audio player range. A&ultima SP1000 is armed with advanced CPU providing exact musical detail without distortion.

      Astell & Kern SP1000


      Superior Audio
      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.

      Powerful Performance
      Equipped with an octa-core CPU which allows the player to produce the exact musical detail present in the original recording without distortion and provides a quick, lag-free operation. It features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface.

      User-Friendly Design
      By placing the power button on the volume wheel located on the side of the SP1000 instead of on the top, users can control the volume and turn the LCD screen ON/OFF, all with one simple control. Song and player information is sharp, colourful and easy to read on the larger, brighter screen.

      Next Generation Charging & Transfer
      USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable. Charging with a fast charger (at 9V/1.67A) takes only two hours and allows up to 12 hours of continuous playback.

      Design Concept
      Equipped with sophisticated volume wheel, the SP1000 delivers advanced visual and textual details with precision. It allows for 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 ageing and external shock.
