The A&ultima SP1000: delivering the ultimate Astell&Kern technology.

Get Both High Output
and Vivid Sound

Traditional audio has suffered from noise and
distortion as power output is increased.
Astell&Kern’s advanced audio design and signal
management technologies used in the A&ultima
SP1000 brings more power output with less noise
and minimal distortion.

Independent DACs for the left and right audio
channels provide a wider soundstage and better
stereo separation.
Each AK4497EQ DAC provides rich and vivid audio
reproduction, allowing the listener to enjoy the
sound as it was meant to be heard.
