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 and balanced 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.

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 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 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 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.

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 RCA analog input/output. The ACRO CA1000 harbours 256GB on-board memory that can be expanded up to 1TB via a microSD card slot, meaning users can stockpile thousands of hi-res albums.

Boosted connectivity

A BT Sink function connects the ACRO CA1000 to an external device, such as a smartphone, via Bluetooth, enabling music to be played back in high-quality on the headphone amp. Elsewhere the ACRO CA1000 boasts Bluetooth® 5.0, providing greater range and a more stable wireless connection to headphones and, along with support for 24-bit aptX™ HD and LDAC codecs, offers the best possible wireless sound quality.
