Astell&Kern SP3000M represents the next evolution in the A&ultima series, merging cutting-edge technology with exceptional audio performance. The designers aimed to achieve a compact form factor while preserving the superior sound quality of the flagship SP3000 model. This goal was realized through numerous enhancements to the circuitry, resulting in a device that is both lighter and more compact, yet does not compromise on sound fidelity.
The Astell&Kern SP3000M features a groundbreaking six-channel (Hexa) architecture that distinctly separates digital and analog signal processing. This design enables an unparalleled listening experience characterized by rich and vibrant sound. The device incorporates two independent audio circuits, enhancing sound accuracy, while its lightweight construction ensures that you can enjoy music wherever you go.
The SP3000M merges advanced technology with a carefully considered design. It transcends the typical Hi-Fi player, serving as a comprehensive instrument for audiophiles who appreciate the richness and depth of sound, providing easy access to these auditory experiences at all times.
Innovation and Audio Excellence
The sound circuitry of the player incorporates four AKM AK4499EX DACs along with two AK4191EQ modules dedicated to handling digital signals. This configuration effectively minimizes noise levels, ensuring a pristine audio experience with a dynamic range reaching up to 130 dB, all within the compact design of the SP3000M. To further mitigate electromagnetic interference, the audio unit is equipped with a silver-coated shield, enhancing sound quality by blocking external noise influences.
Dedicated Audio Circuits for Enhanced Sound
The SP3000M showcases a distinctive design featuring independent audio circuits, utilizing separate channels for both balanced and unbalanced outputs. This approach eliminates signal processing losses, enabling the delivery of the purest sound possible without the need to restore the original signal post-amplification.
TERATON ALPHA — The Foundation of Authentic Sound
Employing TERATON ALPHA technology, the player effectively reduces power supply noise and manages power distribution, ensuring stable amplification. Coupled with its six-channel architecture, TERATON ALPHA unlocks the device’s full potential, allowing music to be experienced as it was originally intended.
Performance and Usability
Powered by a Qualcomm Snapdragon 6125 processor and equipped with 8GB of RAM, the Astell&Kern SP3000M ensures rapid system responsiveness and a seamless user interface. This design allows for an uninterrupted music experience, minimizing delays and digital interference. Additionally, the player features an “analog” VU meter, enhancing the listening experience by not only providing volume level feedback but also creating a more immersive musical atmosphere.
Advanced Sound Technologies
The SP3000M incorporates Digital Audio Remaster (DAR) technology, which elevates sound quality by enhancing the sampling frequency. This results in a more detailed and analog-like sound, capturing the subtleties of the original recordings. With six distinct DAC filters, users can tailor the audio output to their personal preferences, while the Crossfeed function alleviates listening fatigue during extended headphone use, simulating a speaker-like sound experience.
Wireless Capabilities and Music Streaming
The Astell&Kern SP3000M features Bluetooth connectivity with cutting-edge LDAC and AptX codecs, providing high-definition wireless audio. The BT Sink function allows users to stream audio from other devices, such as smartphones, directly to the player. Furthermore, with the integration of streaming applications through the Open App Service, the SP3000M effortlessly accesses music from platforms like Tidal and Apple Music, ensuring optimal audio fidelity. This player is an ideal choice for those seeking a compact yet powerful audio solution, equipped with advanced features and exceptional sound quality that highlights every detail of their favorite tracks.
