Astell&Kern has redefined the headphone amplifier with the introduction of the Astell&Kern ACRO CA1000 Headphone Amplifier. Expertly combining high-performance amplifiers with digital audio player (DAP) capabilities in an incredibly compact desktop and portable-friendly form, the powerful ACRO CA1000 delivers the optimal performance from any type of wired headphone.
An array of digital/analogue inputs and outputs also ensures the ACRO CA1000 can be at the heart of any hi-fi set-up and become the ultimate system for head-fi fans.
Amp the sound
To realise any hidden potential and run the most sophisticated and power-hungry headphones, a dedicated amplifier is essential. The ACROCA1000 supports a four-step Gain Level setting that can run high-impedance headphones with a further 15Vrms (Condition No Load) output level – without deterioration of sound quality. Equipped with balanced 2.5mm and 4.4mm and unbalanced 3.5mm and 6.35mm outputs, the ACRO CA1000 can also accommodate a wide variety of headphones.
DAP capabilities
More than just a powerful headphone amp, the ACRO CA1000 also features DAP capabilities, transforming it into the go-to-system for head-fi aficionados. A titling 4.1-inch touchscreen (up to 60-degrees) enables easy control of the player and amp settings with an intuitive Android OS and feature set that is taken from its award-winning portable DAPs.
It is also equipped with an 8,400mAh large capacity battery to provide up to 10.5 hours playback.
Hi-res credentials
A digital-to analogue converter (DAC) contributes majorly to how close to the original recording the listener will experience. The ACRO CA1000 arrives with a high-quality, high-performance Quad ES9068AS DAC that delivers a clear, detailed sound without distortion.
The Quad-DAC also supports high-resolution audio playback up native DSD512 and 32bit/384 kHz, enabling the music fan to get even closer to the original studio sound, while revealing musical details never heard before.
Heart of a Hi-Fi
An array of inputs and outputs allows connection of digital and analogue sources to expand the systems capabilities. These include Optical, Coaxial, Type-C USB digital inputs/outputs and also RCA analogue input/output. The ACRO CA1000 harbours 256GB on-board memory that can be expanded up to 1TB via a microSD card slot.
