The Most Advanced Asahi Kasei DAC Chips, Dual AK4499EQ

The AK4499EQ DAC chip uses the most advanced ‘Current Output Architecture’ technology. To take full advantage of this new architecture, Astell&Kern redesigned the Op Amp and analog amp block configuration completely. The new circuit design optimizes the current consumption and brings out the most from these new DAC chips. The combination of the SP2000 and AK4499EQ chips provide mind-blowing audio quality.

Newly Designed Audio Circuitry

The SP2000 is the first Astell&Kern player to use separate, independent audio channels between the Unbalanced and Balanced outputs. This design offers much more power than ever before, with 6Vrms for Balanced output and 3Vrms for Unbalanced output. With this design, the SP2000 offers the ultimate audio experience as Astell&Kern’s newest flagship player.

32bit/768kHz, Native DSD22.4MHz Support

SP2000 is the first Astell&Kern model to support 32bit/768kHz and DSD512 (22.4MHz) playback natively without compression or loss.

Two Times the Internal Storage, 512GB

512GB internal storage can hold up to 700+ CDs or 8,000+ tracks of FLAC files (60MB/track). With the addition of a 512GB microSD card, the SP2000 can support over 1TB of storage space.

Dual Band Wi-Fi (2.4/5Ghz)

The SP2000 supports Dual Band Wi-Fi (2.4/5Ghz, b/g/n/ac) with an improved 3-dimensional antenna design. With a stronger wi-fi signal and faster speeds, music streaming from the most popular services is better than ever on the SP2000.

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.
