Astell&Kern A&ultima SP2000 High-Fi Digital Audio Player (DAP)


Request A Price Match

Forget the compare-and-contrast charts. If you’re looking for the best, most high-fi, most make-the-angels-weep digital audio player (DAP) available, you literally can’t do better than the A&ultima SP2000. This is the uncontested King of Daps. 

Sublime Sample Rate

Simply speaking, the higher the sample rate of a song, the better quality the music. A CD’s sample rate is 16bit/44.1kHz. The SP2000’s is 32bit/768kHz. That’s *checks notes* a lot better. Warning: your pleasure center will explode. 

Impossibly Pure Sound

Here’s a game idea: crank the SP2000 until you hear noise. Go ahead, we’ll wait. (With a signal-to-noise ratio (SNR) of 124dB, you’ll be cranking this ultra-clean DAP for a long time.) 

Blisteringly Fast

The SP2000 was built on the principle that a DAP should be fast. You’ll notice this principle at work in its boot times, file transfers, and processing speeds, powered as they are by a cutting-edge octa-core processor. You’ll notice it when streaming high-res tracks over dual-band WiFi. And you’ll notice it when the fast-charging battery gets you back up and running in no time, every time. 

DAP of Steel (or Copper)

Stainless steel and copper are known for their corrosion-resistance, durability, and stunning good looks. They’re also known among the audio community for reproducing top-notch sound. Wear either proud or protect them even further with an included leather case. 

Store All the Music

With 512GB of internal memory, plus support for an additional 1TB of external memory, you’ll never want for storage again. 


Would you die a little if we told you that MP3 files deliver just 10% of original studio recordings? That’s one-tenth of the nuance, depth, and richness that the artist intended for you to hear. MQA (Master Quality Authenticated) files, on the other hand, deliver the full, uncompressed sound of the original master recordings in all their richness. The A&ultima SP2000 supports this technology, delivering the best possible version of the music you love.
