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

    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 Gold 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 Gold 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 Gold 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 Gold 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 Gold 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.

    MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Astell&Kern SP1000M includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.
