Introducing Astell&Kern’s new flagship


This is the ultimate. Cutting-edge technology combines with unique aesthetics results in a completely uncompromised listening experience - SP2000 is our flagship player, and the best-sounding portable music player ever made.


Dual AK4499EQ DACs

Experience the highest of high-resolution audio thanks to a pair of AKM AK4499EQ DAC chips. By completely rethinking the circuit design to optimise current consumption and extract every shred of performance from these class-leading DACs, we can support 32-bit/768kHz and DSD512 audio files natively, without loss or compression.

Huge internal storage

The SP2000 has a massive 512GB of internal memory, enough to hold well over 1000 albums at CD quality. Add a microSD memory card to expand up to a huge 1.5TB - it’s enough storage to take week’s-worth of high-resolution music with you, wherever you go.

Power and independence

For the first time, we’ve specified separate, independent audio channels between the balanced and unbalanced outputs. The result is abundant power: 6Vrms for the balanced output and 3Vrms for the unbalanced output. Which means the SP2000 will comfortably drive any headphones you choose, at any volume level you desire.

Ultimate streaming stability

With dual-band wi-fi (2.4/5GHz) facilitated by an all-new three-dimensional antenna design, the SP2000 preserves the signal strength and speed your favourite streaming service demands to function at its best.

Form complementing function

The elegant, sophisticated design of the SP2000 features sandblasted aluminium, machined from a single, solid block and finished in either copper or stainless steel. Along with the edge-to-edge high-definition touchscreen, it defines the SP2000 as a beautiful object as well as an extraordinary music player.

“…it sounds like no other personal media player (PMP) we’ve heard… both as a straight-up PMP in a desirable headphones set-up and as a streaming-capable source for your speaker-led hi-fi – the A&ultima SP2000 is the sort of musical and multi-talented device that’s otherwise hard to come by.”
