Astell & Kern Ultima SP1000M Music Player

Ultra Portable & Ultra Performance, A&ultima SP1000M


Astell&Kern constantly strives to master the philosophy of delivering original sound.
So far, we believe that the A&ultima SP1000 is the optimal product that produces the highest-quality audio.

We were not sure whether it was possible to come up with a product that is different from the SP1000 while delivering the same sound quality,
but we decided to take up the challenge so that more people could experience our products’ fidelity.

There were many trials and tribulations in making the SP1000, our best product, smaller.
We were determined to not compromise sound quality in the process, and we ultimately developed the second A&ultima product, the SP1000M.


Octa-Core CPU for Next-Level Performance
AK4497EQ Dual DAC for Highest Sound Quality
4.1 Inch HD Display
Highest Quality Audio of SP1000
Portable and Durable Aluminum Body
DNLA-Based AK Connect App
Open APP Service


The lightweight and portability of the SP1000M enables the user to enjoy original sound playback anytime and anywhere.

The A&ultima SP1000M achieves greater portability, without sacrificing the level of performance found in the original SP1000.
