Astell&Kern A&ultima SP1000M Portable High-Resolution Digital Audio Player ***DEMO***



    Ultra Portable & Ultra Performance, A&ultima SP1000M

    Astell&Kern constantly strives to master the philosophy of delivering original sound. So far, they believe that the A&ultima SP1000 is the optimal product that produces the highest-quality audio.

    They were not sure whether it was possible to come up with a product that is different from the SP1000 while delivering the same sound quality, but Astell&Kern decided to take up the challenge so that more people could experience their product's fidelity.

    There were many trials and tribulations in making the SP1000 their best product, smaller. Astell&Kern were determined to not compromise sound quality in the process and they ultimately developed the second A&ultima product, the SP1000M.

    • 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 lightweight and portability of the SP1000M enables the user to enjoy original sound playback anytime and anywhere. The A&ultima SP1000M achieves greater portability, without sacrificing the level of performance found in the original SP1000.


    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

    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.
