The SP2000 is the latest portable player from the Astell&Kern A&ultima line and the first to use separate, independent audio channels between the Unbalanced and Balanced outputs. Featuring two AK4499EQ DACs, SP2000 offers more power than ever before for the ultimate audio experience.

A New Norm

This new flagship DAP offers 6Vrms Balanced output and 3Vrms Unbalanced output and supports up to 32-bit/768KHz bit-to-bit playback of high-resolution PCM audio and native playback of DSD up to DSD512. It also features an Octa-Core CPU, a 5-inch touchscreen, 512GB of internal memory (double of previous Astell&Kern players), MQA support (pending final testing and certification) and dual-band Wi-Fi with a stereo antenna, for improved network performance when streaming music.

Roon Ready

Your one-stop-shop for a curated music library, Roon connects your existing music files with content from your streaming services and connects it all to photos, bios, reviews, lyrics, and concert dates. It puts all of your music in one searchable place.

Roon is a music management and listening solution that takes a very different approach to interact with your music. Instead of seeing a spreadsheet-like view of your music (as with iTunes and almost all other media systems), Roon provides a very rich non-list based experience, using credits, artist relationships, genres, lyrics, concert/tour dates, artwork, and more to allow for informative navigation and exploration of your library.

Roon manages digital music files collected on hard drives and networked storage. It can also watch your iTunes library, and optionally integrate with the music streaming service TIDAL.

Design Concept

The design of the SP2000 improves upon its predecessor, enhancing the details and maintaining the unique crown pattern volume/power wheel. The music player will be available in Stainless Steel and Copper bodies.

The SP2000 DAP features two of the latest Asahi Kasei flagship DAC, the AK4499, and an octa-core CPU. This new flagship player supports 32bit/768kHz, DSD512, dual-band wireless connectivity (2.4 & 5 GHz), and an increased power output of 6Vrms Balanced. With a 5-inch HD (720 x 1,280) display screen and internal storage of 512GB, the SP2000 is available in both Stainless Steel & Copper finishes.

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.

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).


MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Visit for more information. Astell&Kern SP2000 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.
