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 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.
