Astell&Kern ACRO CA1000T – High-End Headphone Amplifier & Desktop Audio Player with Tube Technology

The ultimate Head-Fi solution for home, office, and on the go

The Astell&Kern ACRO CA1000T combines a high-end digital audio player, desktop headphone amplifier, DAC, and streaming player into a single device. Equipped with state-of-the-art audio technology, a powerful battery, and the innovative Triple AMP system, the ACRO CA1000T delivers uncompromising sound quality – whether you use it at your desk, in the living room, or while traveling.

With its combination of dual ESS ES9039MPRO DACs, KORG Nutube vacuum tube technology, TERATON ALPHA, and an output power of up to 15 Vrms, the ACRO CA1000T sets new standards in the realm of high-quality Head-Fi systems.

All-in-one Head-Fi system for the most demanding users

The ACRO CA1000T was developed specifically for audiophiles looking for a complete desktop audio solution without the need for additional components.

Thanks to its integrated battery, the device operates completely independently of the power grid, allowing for uncompromising high-end sound even when on the move. At the same time, numerous analog and digital inputs and outputs ensure maximum flexibility when connecting headphones, active speakers, or external audio sources.

Dual ESS ES9039MPRO DAC

Inside, the latest generation of reference DACs from ESS Technology is at work.

Two ESS ES9039MPRO DACs ensure exceptionally precise signal processing with tremendous dynamics, excellent channel separation, and minimal noise. High-resolution music files are reproduced with impressive naturalness and maximum detail.

TERATON ALPHA – Astell&Kern's audio technology

With the exclusive TERATON ALPHA technology, Astell&Kern consolidates its entire experience in the high-end audio sector.

Through intelligent power supply, high-precision signal processing, effective noise suppression, and optimized amplifier technology, exceptional transparency, naturalness, and musicality are achieved. Even the finest details are preserved with complete fidelity.

Triple AMP – Three amplifier characteristics in one device

A highlight of the ACRO CA1000T is the innovative Triple AMP system.

Depending on your personal listening preference, you can choose between three different amplifier modes:

OP AMP Mode

The operational amplifier mode delivers maximum precision, high resolution, and a neutral, dynamic sound.

Tube AMP Mode

The integrated KORG Nutube twin triode tubes produce the warm, harmonic, and musical character of classic tube amplifiers.

Hybrid AMP Mode

In Hybrid mode, the advantages of both technologies are combined. The result is an exceptionally balanced soundstage with the naturalness of a tube amplifier and the precision of modern semiconductor technology.

Fully balanced tube circuitry

The ACRO CA1000T features two KORG Nutube vacuum tubes, which operate in a fully balanced signal path.

Unlike conventional tube amplifiers, the left and right channels are processed completely separately. This significantly reduces the noise floor and creates a particularly natural, spacious, and harmonic musical reproduction.

Four gain stages up to 15 Vrms

With four gain stages and an output voltage of up to 15 Vrms, the ACRO CA1000T is suitable for both sensitive in-ear monitors and power-hungry high-end headphones.

Separate signal processing for balanced and unbalanced outputs ensures optimal control, minimal distortion, and the highest sound quality at all times.

Extensive connection options

The ACRO CA1000T offers a multitude of analog and digital inputs and outputs for almost any audio application.

All input and output options can be conveniently selected via the integrated touchscreen – even when multiple devices are connected simultaneously.

This makes the ACRO CA1000T equally suitable as a desktop DAC, streaming player, headphone amplifier, or as the central audio hub of a high-quality Hi-Fi system.

Optimized tube design against microphonics

For maximum sound quality, Astell&Kern developed a special housing concept to reduce microphonic effects.

The sensitive KORG Nutube tubes are mounted in flexible silicone holders and are additionally magnetically decoupled from the circuit board. This effectively minimizes shocks and vibrations, allowing the tubes to operate particularly stably and without interference.

Mobility without compromise

Thanks to the integrated high-performance battery, the ACRO CA1000T can be operated completely independently of the power grid.

This allows you to enjoy the sound quality of a desktop system wherever you want to listen to music – in the office, the living room, or while traveling.
