Astell & Kern ACRO CA1000

The Astell & Kern ACRO CA1000 is a high-performance portable headphone amplifier with a beautiful digital audio player built-in!

The aluminium body and wheels produced with CNC precision represent Astell & Kern’s cohesive technology, it is robust yet delicately finished.

ACRO CA1000 has a tilting display that can be adjusted to an optimal position depending on where it is placed on a desk or table. The display can be freely adjusted up to 60 degrees to suit your environment.

The digital music player, which cannot be detached from the unit, has a 4.1-inch touchscreen that can tilt upwards (up to 60-degrees), allowing users to easily control playback and settings through its Android OS, or alternatively lie flat within the aluminium chassis.

The player can also receive music over Bluetooth from a connected phone (via the BT Sink function) and send playback wirelessly to a pair of wireless headphones thanks to Bluetooth 5.0, aptX HD and LDAC support. Wi-fi is on the menu too. Want to connect an external source? Inputs spanning optical, coaxial, USB-C and RCA are all at your service.
