Astell&Kern A&ultima SP1000M
Astell&Kern constantly strives to master the philosophy of delivering original sound.
So far, they believe that the A&ultima SP1000 is the optimal product that produces the highest-quality audio.
They 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 they decided to take up the challenge so that more people could experience their products’ fidelity.
There were many trials and tribulations in making the SP1000, their best product, smaller.
They were determined to not compromise sound quality in the process, and they ultimately developed the second A&ultima product, the SP1000M.
