Main Features

Constantly striving to improve the audio experience, Astell&Kern attempted to match the audio quality of the SP1000 in a new product. Determined not to compromise sound quality while making a smaller, more accessible product, they ultimately developed the second product in the A&ultima line.

The A&ultima SP1000 is the optimal product that produces the highest-quality audio. Lightweight and portable, the SP1000M enables the user to enjoy original sound playback anytime and anywhere.

  • Octa-Core CPU for Next-Level Performance
  • AK4497EQ Dual DAC for Highest Sound Quality
  • 4.1 Inch HD Display
  • Highest Quality Audio of SP1000
  • Portable and Durable Aluminum Body
  • DNLA-Based AK Connect App
  • Open APP Service


The “M” in SP1000M does not stand for one specific word, but rather encompasses many characteristics that the product aims to pursue.

  • MINI: Smaller than the SP1000
  • MOBILITY: More compact design for portability
  • MAXIMUM: Produces the highest-quality audio
  • MANIA: For users who are obsessed with true, original sound
  • MATE: Perfect anytime and anywhere
  • MOMENT: Free of distractions, get lost in the music

Premium Portability

The A&ultima line of players by Astell&Kern feature the latest technology and high-end audio performance that is available in a portable player. The A&ultima SP1000M is equipped with two AK4497EQ DACs. A separate DAC (Digital to Analog Converter) is dedicated to each independent left and right audio channel, producing a wider soundstage and better stereo separation. With the addition of an Octa-Core CPU, the A&ultima SP1000M not only boots faster, but is able to process digital audio playback without lag or compromise in sound. This will provide the ultimate sound experience of any player currently on the market. Astell&Kern’s advanced audio design and signal management technologies used in the A&ultima SP1000M brings more power output with less noise and minimal distortion.

Vivid Images

Equipped with a 4.1 inch, HD-resolution screen, the A&ultima SP1000M provides sharp images and vivid colors to display album art, music playback and player information. The redesigned, music-centric GUI that debuted on the full-sized SP1000 is also used on the SP1000M. USB Type-C 3.0 support allows data transfers that are twice as fast as other Astell&Kern players. The A&ultima SP1000 also provides 10 hours of music playback and includes support for fast charging.

Using Open APP Service

The Open APP Service enables the user to install specific APK music streaming apps to the device. Copy the desired APK into the Open Service folder of the product and install the relevant App in the Menu-Service of the product.

Advanced User Interface

While the A&ultima SP1000M has the same intuitive menu composition as its predecessor, the SP1000, its user interface has been improved with the optional Virtual Back Key, which enables users to control the device more easily and conveniently.

Use the Floating feature to place the Virtual Back Key at a desired location or disable it by simply dragging it to the middle of the screen or turning it off from the Settings menu.

Great Performance for the Ultimate Experience

The A&ultima SP1000M is 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.

The A&ultima SP1000M features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience.

Ultimate Sound Quality

The latest AK4497EQ dual-DAC design and the upgraded CPU in the A&ultima SP1000M allows for accurate playback of native 32bit/384kHz audio with no compromise on sound quality. The music is played back, bit-for-bit, just as the artist and engineer intended for it to be heard.

The A&ultima SP1000M also supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible.

Faster Charging, Quicker File Transfer

Next generation USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable.

USB 3.0 protocol transfers data twice as fast when compared to other Astell&Kern players. Charging with a fast charger (at 9V/1.67A) takes only 3 hours and allows up to 10 hours of continuous playback.

* The maximum 10-hour continuous play is based on 16-bit/44 kHz, FLAC file format, screen off, 75 of volume playback.
* Fast charger (9V/1.67A) and general Charger (5V/2A) are not included in the package.

Design Concept

Inspiration for the design of the SP1000M comes from irregularly patterned natural stones combined with Lapis Lazuli, one of the oldest of all gems, to create the SP1000M’s color - Lapis Blue.

Lapis Blue

Lapis Lazuli, whose history stretches back to 5,000 BC, was a precious gem used in Mesopotamia and Egypt during ancient times. The SP1000M’s vivid blue represents youth, enthusiasm and power. The darker blue highlights appear at different angles to add elegance to the A&ultima product.

The dakota leather used in the SP1000M bundle leather case is a premium vegetable leather made from an Italian tanner named 'Ra Perla Azura', which is a manufacture of Italian and French origin.

'La Perla Azura' was founded in 1967 and has a long history over 50 years. It is located in 'Santa Croce sull´Arno' which is only high-end leather production district in Italy.
