Introducing Astell&Kern's new flagship, the A&ultima SP2000.


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.

    SP2000 vs SP1000

    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

    As CD-ripping and offline storage of streaming content gets more popular, the SP2000 offers twice the amount of internal storage compared to SP1000. 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)

    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 (2.4/5Ghz, 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.

    Roon Ready Support

    Roon is an incredibly rich and engaging way to browse and organize your music. It runs on most Mac, Windows, and Linux PCs, or on other products which include Roon Core. Being Roon Ready means that Astell&Kern network players transparently discover and connect to Roon without any configuration, and bit-perfect audio is delivered from Roon to your network player. Together, Roon and Astell&Kern deliver the power, flexibility, and performance of networked audio, with the easiest setup and highest reliability available.

    The design motif of the SP2000 resembles the dispersion of light around the player. The main focus of the design is the volume wheel, which that is the starting point of the usability design. The exquisite details of the crown pattern crossed over the pattern of the body, reflect the craftsmanship and quality of the player.

    The back stainless steel panel encompasses Astell&Kern’s philosophy of bringing listeners the original performance, without compromise, by featuring a full back plate without screws. This provides a more solid feel to the player and enhances the natural beauty of the body materials used.

    Introducing the new SP2000 Onyx Black. This sleek and premium black coated stainless steel was made possible using PVD (Physical Vapor Deposition) coating technology. It is environmentally friendly and the results are finishes that provide long-lasting protection and durability, are resistant to chemicals, easy to maintain and protect against corrosion and wear. PVD coating has been used for products where higher endurance and reliability is demanded, including medical instruments, luxury accessories and more.
