All-In-One Head-Fi Audio System,
ACRO CA1000T

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.

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.

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.

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.
