Astell&Kern A&ultima SP1000M

Astell&Kern has last Friday during a press event in Beijing, China announced the addition of the SP1000M to A&ultima Flagship Player Line.

Being the latest member of Astell&Kern’s A&ultima line of players which feature the latest technology and high-end audio performance that is available in a portable player.  The A&ultima SP1000M is equipped with two AK4497EQ DAC (Digital to Analog Converter) chips. A separate DAC chip is dedicated to each independent left and right audio channel, producing a wider soundstage and better stereo separation. Coupled with the inclusion of an Octa-Core CPU, the A&ultima SP1000M not only boots faster but is able to process digital audio playback without lag or compromise in sound.

Weighing in at just 203g, the new SP1000M player has been reduced to almost half of the full-sized SP1000 which averages 387.25g.

The DAP is equipped with a 4.1 inch, HD-resolution screen facilitating sharp images and vivid colours to display album art, music playback and player information. The redesigned, music-centric GUI that debuted on the full-sized SP1000 is also implemented on the SP1000M with USB Type-C 3.0 which supports high-speed data transfers. The DAP also provides 10 hours of music playback and includes support for fast charging.

At the launch, the SP1000M is available only in Lapis Blue and features an all-aluminium body.  The DAP will be equipped 128GB of internal memory with a microSD card slot supporting additional memory (currently up to 512gb).

Like the SP1000, the A&ultima SP1000M will include support of native playback of 32-bit/384kHz high-resolution PCM audio and native playback of DSD audio, up to Quad-rate (DSD256) and features 4.2Vrms Balanced output, a Parametric EQ (PEQ), VCXO Reference Clock (Femto Clock) for minimal jitter, Wi-Fi connectivity, support for the AK Connect app, USB DAC function, DLNA networking support, OTA software updates, digital audio output via USB, apt X HD Bluetooth, and support for high-resolution music streaming services including TIDAL, MOOV and Groovers+ (support for streaming services varies by country).

The A&ultima SP1000M will make its official US debut at Rocky Mountain Audio Fest, October 5 – 8, 2018.  It is expected to retail for USD 2,399 and will be available in October 2018.


The company also took the opportunity to announce Android APK support via OpenAPK, allowing users to install additional music streaming services to their player by simply copying and installing the corresponding APK file for the music service they wish to add.
