Design

The ACRO CA1000T inherits its form and style from the previous model, the CA1000, with subtle redesigns to better represent its improved powerful performance.
We chose a darker color to tone down the increased complexity of the parts such as the amp button and the upper lighting glass, giving it a more impactful design aesthetic compared to the CA1000.
The upper lighting glass shows an image of the amp gleaming through the vacuum glass when the vacuum amp is in operation in an etched pattern, while simultaneously allowing users to easily understand the amp mode’s current status.
The volume wheel design, which is the key AK interface and has a gently widening diameter, expressing a powerful burst of output that has been compressed through the vacuum amp. The golden-colored accent ring was changed from aluminum to stainless steel to add a hint of luxury to the design, while also allowing it to have a more intense reflection that juxtaposes it against the dark color of the rich gray body.
We aim to deliver the unique and beautiful design identity of Astell&Kern along with convenient utility that conveys the sheer joy of sound. The ACRO CA1000T has a tilted display that can be adjusted with just a gentle touch, but is still heavy enough to stand firmly on a desk or a table. You may adjust it by up to 60 degrees to suit your environment and preferred viewing angle.

4-levels of gain and up to 15Vrms output for the Perfect Head-Fi Setup

To run the most detailed IEMs and most demanding headphones perfectly, an output that matches the characteristic of the receiving device is required. The ACRO CA1000T supports 4 gain level settings so that almost any headphones can be driven to an optimal state.
The 4-levels of gain setting can create the ideal output for a device’s characteristics and sound, allowing users to fine tune and dial in their desired volume output. And with up to 15 Vrms output, it can run high-impedance headphones with ease.

The output ports' electrical capacity has been raised to add stability when operating devices with different impedances at the gain level setting, and the separate balanced and unbalanced volume controllers optimize electricity flow and reduce noise for the best sound.

With the ACRO CA1000T, you can enjoy optimal device performance and pure sound that touches your heart.

The world's first Use of the Newest ESS Flagship DAC

The ACRO CA1000T is designed with dual ES9039MPRO, using the newest flagship DAC from ESS for the first time ever to offer more vivid and voluminous sounds that surpass your imagination.

The ES9039MPRO is an additional ES9039PRO model that has a built-in stereo hardware MQA renderer. It has even more advanced modulation than the existing flagship DAC to reduce power consumption, noise and distortions inside the DAC for enhanced audio performance.

Astell&Kern invented and optimized a new design of amp block to heighten the performance of the ES9039MPRO, allowing it to offer more balanced and intense sounds with deeper and richer bass sounds and clear highs.

Crossfeed, Speaker effect when listening through headphones

In a headphone environment in which the left and right channels are clearly separated, ear fatigue may increase during prolonged listening. The moment you turn on Crossfeed, the experience of crisp, but comfortable sound begins.

Crossfeed mixes parts of the original signal from one channel and sends that signal to the opposite channel with a time difference to center the sound image.

Through the use of detailed settings such as Shelf Cutoff, Shelf Gain, and Mixer Level,
you can set the level of crossfeed according to your listening preferences.

Custom design to minimize microphonic noise

A special custom design minimizes microphonic noise that may be caused by external shocks and vibrations.

To address the structural issue of vacuum tubes, where microphonic noise is created even by the smallest shocks or vibrations, we repeatedly developed new designs and conducted thorough reviews and testing during prototyping.
Both sides of the vacuum tube are fixed with flexible silicon covers to minimize shocks and a magnetic force is used to physically separate it from the PCB, offering greater stability and isolation when the tube is operational.

Astell&Kern is committed to designing these small elements and aspects that create the unrivaled differences between our products and the sound of competitors.
