Astell&Kern A&ultima SP3000M Digital Audio Player 

Compact Size, Limitless Sound
The A&ultima series continues to present advanced and innovative technology and the standard of perfect sound. They renewed their commitment to this goal and began to delve deep into the concept of true portability with unrivalled performance and unmatched sound performance

This device is designed for seamless integration into modern digital ecosystems.

The SP3000M also features the AK File Drop function for hassle-free file transfer, along with ReplayGain for consistent volume levels across different tracks.

Elegant Design and Build
Beyond its superior sound capabilities, the SP3000M stands out with its elegant design. Inspired by the tension between a diamond and its setting, the design incorporates a rhombus shape and a carefully crafted volume knob. The etched cross pattern on the back glass pays homage to the SP3000 while showcasing the distinct identity of the SP3000M. This combination of cutting-edge technology and refined aesthetics makes the SP3000M a truly premium portable audio player.

Stunning Audio Performance with Independent Dual Audio Circuits
In order to create a truly innovative DAP, not just a great DAP, we tried to overcome the limitations of sound by envisioning an independent dual audio circuit that has never been attempted by anyone featuring a HEXA structure with unbalanced and balanced outputs.

Drive Your Music, Latest Snapdragon Octa-Core CPU
A&ultima SP3000M is equipped with a Snapdragon 6125 Octa-core processor, so you can enjoy the overwhelming sound, with faster system response and a redesigned generation user interface that moves comfortably and smoothly.

Featuring a high-performance CPU and improved 8GB of DDR4 memory, which is twice the amount commonly used in other digital audio players, the more powerful system is stable with fast and fluid movement.

VU Meter GUI for Complete Musical Immersion
SP3000M comes with a VU Meter GUI, which debuted on the SP3000T and was well-received by consumers for an even more immersive experience. The VU Meter, an iconic piece of audio equipment with a long-standing history, displays voltage levels of voice signals to aid volume measurement and adjustment. Beyond its utilitarian function, the VU Meter’s unique design and retro charm help to enhance the immersive music-listening experience.

Digital Audio Remaster Technology for Even More Vivid Original Sound
The SP3000M is equipped with Digital Audio Remaster(DAR) technology, which was developed to deliver fine sound at higher sample rates. DAR technology is developed to upsample the sample rate of the sound source being played to go beyond the limits of the source format. The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music and rich sounds at a higher level.

Sound Design With DAC Filters
With the SP3000M, you can have fun creating your own sound style by selecting various DAC filters provided by the DAC manufacturer. Design your own sound with 6 different DAC filters.

Streaming and AK Connect Network Play — Designed for Convenience
Astell&Kern’s audio players are seamlessly integrated with external streaming apps through the Open App Service. Enjoy high-quality streaming from platforms like Tidal and Apple Music with the unparalleled fidelity of the SP3000M. With AK Connect, our network play feature, you can easily access and play/download music from PCs and devices connected to the same network as the SP3000M in real time.
