Astell&Kern ACRO L1000 DAC / Headphone Amp

The design of the ACRO L1000 resembles the ‘Golden Ratio’ of the Parthenon of Athens. Like the Golden Ratio stays consistent and never changes, Astell&Kern has designed the L1000 to serve the never-changing value of music. Its design signifies something that should never be changed – the original sound.

Therefore, the image of the historical building is the motif, and the L1000 represents a distortion-free sound. The composed geometrics of the cylinder and the square reaffirms the everlasting meaning of great music paired with modern technologies to provide the best listening experience. The entire body is made of aluminum, which adds aesthetics, and allows for an ergonomic volume control.

As it sits on a desk, the 30-degree angle will naturally fit your everyday use. The size of volume wheel is designed to fit for your hand, and the knurled pattern allows the perfect feel of being in control of your music. The accent of the LED rim lights around the volume wheel adds a subtle, yet comfortable music listening ambience, and the 12 dots of LED shows the status of music playback volume.
