Astell&Kern Acro L1000 Headphone Amplifier with DAC

Acro L1000 Headphone Amplifier with DAC

Astell&Kern introduces a new sub-brand of desktop audio products called ACRO. Astell&Kern has taken their expertise in designing best-selling, world-class portable audio devices and put that knowledge in to the first desktop audio product, the ACRO L1000. The ACRO L1000 is the first Desktop Headphone Amplifier from Astell&Kern.

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.

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 ACRO L1000 provides multiple audio output options to fit your needs.
It can be connected to a universal 3.5mm/6.3mm jack, or to a headphone or earphone with a 2.5mm/4-pole XLR balanced jack. Unlike other headphone amplifiers, the ACRO L1000 features speaker binding posts offering a maximum audio output of up to 15W per channel at 4 ohms.

The ACRO L1000 can be connected to your PC or MAC via Micro USB cable.
Using an Astell&Kern portable player as a source device will give you more powerful audio experience with your L1000.
