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.
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.
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.
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.
