Astell & Kern A&ultima SP2000 Digital Audio Player
Enjoy premium sonic performance with the Astell&Kern SP2000, an A&ultima Series high-resolution music player offering uncompromising audio fidelity for audiophiles and music lovers. Dual AKM AK4499EQ DAC chips and redesigned circuitry provide a wide, flat frequency response, a high signal-to-noise ratio, and independent channels for the balanced 2.5mm and unbalanced 3.5mm outputs. The 3.5mm port doubles as an optical output for easy hookup to an external DAC.
The SP2000 supports uncompressed bit-to-bit audio transmission in PCM resolutions up to 32-bit / 768 kHz or DSD resolutions up to 22.4 MHz. Dual-band Wi-Fi support allows you to wirelessly stream music from a mobile device or computer. When it comes time to load music onto the SP2000, its 512GB internal memory and compatibility with large-capacity microSD cards (up to 512GB) ensure that you won't run out of storage space anytime soon.
With an octa-core CPU, a high-definition 5" touchscreen, and a sleek multifunction wheel, the SP2000 is powerful, fast, and easy to control. Its internal battery delivers up to eight hours of continuous playback time and supports standard and fast charging via USB. The SP2000 includes a USB Type-C cable and a complementary green leather case.

A&ultima SP2000 vs SP1000
Newly Designed Audio Circuit
Dual AKM AK4499EQ DACs are employed to allow the SP2000 to use separate, independent audio channels for the unbalanced and balanced outputs. Astell&Kern redesigned the op-amp and analog amp block configuration to take advantage of the architecture of the AK4499EQ. The new audio circuit optimizes the current consumption and helps the DAC chips achieve peak performance, yielding a flatter frequency response, a higher signal-to-noise ratio, and lower distortion than previous flagship models.
Supports High-Resolution Uncompressed PCM and DSD
The SP2000 is the first Astell&Kern model to support 32-bit / 768 kHz and DSD512 (22.4 MHz) native playback without compression or loss. The 32-bit DACs ensure bit-to-bit playback with no reduction in bit depth or sample rate.
With streaming music services becoming more popular, stronger and more reliable network reception becomes even more important for your audio experience. The SP2000 supports dual-band Wi-Fi (2.4 and 5 GHz) with an improved three-dimensional antenna design.
Plentiful Internal and External Storage
Equipped with 512GB of internal memory, the SP2000 offers twice the amount of internal storage compared to the previous flagship model. 512GB is enough to hold the data from over 700 ripped CDs or 8000 tracks of FLAC files (60MB per track). Insert a microSD card (up to 512GB) for even more storage space.
Increased Audio Output Power
With more power than any previous Astell&Kern players—6Vrms for the balanced output and 3Vrms for the unbalanced output, the SP2000 is ready to drive your favorite headphones to their full potential.
Great Performance for the Ultimate Experience
The A&ultima SP2000 is equipped with an octa-core CPU which allows the player to produce the exact details present in the original recording without distortion and provides a quick, lag-free operation.
The A&ultima SP2000 features faster booting times, speedy file transfers, lag-free processing and an intuitive user interface for the ultimate player experience.
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-->Services of the player.
