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.

Full Balanced Circuit with Dual-Tube

The ACRO CA1000T has dual Twin Triode KORG Nutube tubes, which were implemented for the first time in our award winning SP2000T, offering advanced tube sounds. When a product is equipped with a Dual DAC, and one vacuum tube there must be a separate circuit to convert the signal to Balanced right before the output terminal. This structure requires a process to convert an unbalanced signal to a balanced signal, during which, noise gets amplified in the process. The CA1000T, however, offers a complete balanced circuit that separates left and right channels with two vacuum tubes, creating even more natural and softer sounds. Both Tube AMP mode and OPAMP provide a powerful 15 Vrms output, and the headphone ports allow you to enjoy the unique sounds of vacuum tubes without any limitations.

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.

TRIPLE AMP SYSTEM is the Next Generation of AMP Technology

The ACRO CA1000T exceeds the standard approach to AMP Mode selection, based on the type of music you are listening to. Select between TUBE AMP mode, OP AMP mode, or the brand-new HYBRID AMP mode. OP AMP mode puts Astell&Kern's AMP technology expertise to use, delivering extreme clarity and dynamic sound, while TUBE AMP mode provides a uniquely warm and musical sound. HYBRID AMP mode - a first for digital audio players - enhances the resolution and clarity of the existing TUBE AMP mode to express more musical detail. HYBRID AMP mode, combines the advantages of retro analog performance and high-resolution output, giving you the pleasure of a brand new tonal characteristic. Experience the unique sound enhancements that this AMP technology has to offer.

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.

Extensive Input/Output Options

The ACRO CA1000T offers an extensive range of input/output options that can meet the needs of audiophiles looking to build their ideal Head-Fi system with maximum utility. For greater ease of use, you can change the input/output settings using the touch screen on top of the product while multiple cables and devices are connected.


It would have been impossible to realize the powerful output from the most detailed headphones and the complicated signal path of a dual tube and triple amp system with minimal noise without TERATON ALPHA, AK's Ultimate Sound Solution. Astell&Kern further improved TERATON ALPHA using knowledge learned from the design of the Hybrid Tube System found in our SP2000T and the noise removal from the CA1000. TERATON ALPHA, engineered through endless research, is Astell&Kern's unique technology that has been designed to produce audio playback that is as close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.

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.

Convenient, High-Quality Head-Fi Sound

The ACRO CA1000T goes beyond the limitations of a fixed headphone amp with its ideal Head-Fi audio system that can be setup anywhere you want and can run independently from its internal battery supply. The ACRO CA1000T offers detailed headphone sound thanks to its built-in high-power headphone amp that does not require a connection to other devices. It's an all-in-one Head-Fi audio system that provides great connectivity with external audio devices and speakers thanks to its diverse range of input/output ports, allowing you to easily enjoy network audio playback and music streaming.
