Astell & Kern ACRO L1000 Desktop Amp/DAC

Astell & Kern ACRO L1000 Desktop Amp/DAC


Astell&Kern has introduced a new sub-brand of desktop audio products called ACRO, bringing all the high-resolution music expertise of its award-winning portable players into the home. The new line-up launches with the ACRO L1000, a 32bit desktop headphone amplifier/DAC unit with excellent performance, connectivity and design.

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. USB connectivity means the ACRO L1000 can be used as a desktop amp/DAC to significantly boost the audio performance of your PC or Mac. Unlike most other headphone amplifiers, the ACRO L1000 also offers the option to easily connect to desktop speakers via dedicated, binding-post outputs. These offer a maximum audio output of up to 15W per channel at 4 ohms.

The ACRO L1000 features two AK4490 DAC chips – the same proven performance DACs found in the high-end Astell&Kern AK380 players, and 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.

The ACRO L1000 is beautifully crafted from aluminium, and designed at a 30-degree angle to aid desktop usability.
