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


Newly designed audio circuit

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 6 Vrms 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

* SNR (Signal to Noise Ratio) As the signal-to-noise ratio increases, the clearer the sound becomes.
* THD+N (THD + Noise, Distortion) over the THD + Noise signal rate, less distortion is heard.


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.


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

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


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, a/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.


Twice 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).


Design Concept

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 is the starting point of the usability design. 

The exquisite details of the crown pattern crossed over the pattern of the body, reflect the craftmanship 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.
