Design that is optimized for both use and sound
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, and provides distortion-free 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 maximizes sound clarity, 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 LEDs show the status of music playback volume.
Step up to a new world, the ACRO L1000
Dual High-End AK4490 DACs Built-in
The ACRO L1000 features two AK4490 DAC chips, the same proven performance DACs found in the popular and successful Astell&Kern AK380 players. The Dual DACs deliver proven consistent and high performance digital music playback. With the Dual DAC configuration, the ACRO L1000 delivers superb resolution and rich spatial sound.
The Dual-DAC implementation is re-designed to perform at its best efficiency with the new AMP circuit design in the L1000. This new design allows the ACRO L1000 to deliver master-quality sound with minimal distortion.
PCM playback up to 32bit/384kHz, Native DSD 256 playback supported
The L1000 plays back bit-to-bit high-resolution PCM digital audio up to 32bits. A 32-bit CPU has also been added for the most accurate processing of digital audio playback, without compromising audio quality. As a result, the ACRO L1000 can reproduce up to 32bit/384kHz PCM as originally recorded, with no down-sampling. The L1000 also supports native DSD playback up to 11.2MHz, without conversion.
- The maximum audio output would be limited based on the output capacity of your source device.
