Ultra Portable & Ultra Performance,
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
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.
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.

Inspiration for the design of the SP1000M comes from Iirregularly patterned
natural stones combined with Lapis Lazuli, one of the oldest of all gems,
createsto create the SP1000M's color - Lapis Blue.
Lapis Lazuli, whose history stretches back to 5,000 BC, was a precious gem used in Mesopotamia and Egypt during ancient times.
The SP1000M's vivid blue represents youth, enthusiasm and power. The darker blue highlights appear at different angles to add elegance to the A&ultima product.
The dakota leather used in the SP1000M bundle leather case is a premium vegetable leather made from an Italian tanner named 'Ra Perla Azura'.
It's a manufacture of Italian and French origin.
'La Perla Azura' was founded in 1967 and has a long history over 50 years.
It is located in 'Santa Croce sull´Arno' which is only high-end leather production district in Italy.
The SP1000M Onyx Black case uses Beta leather from NUOVA ALBORA. Beta leather is a high quality leather which contains a large amount of oil as a whole, strong resiliency of scratches, and can sense changes with the passage of time.
