  • Create the ideal output for a device's characteristics and sound, allowing you to fine-tune and dial in your desired volume output. With up to 15 Vrms output, it can power high-impedance headphones with ease.
  • The output ports' electrical capacity have 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.

Upgraded Sound: Latest ESS Flagship DAC

  • Designed with dual ES9039MPRO DACs from ESS, for a vivid and voluminous sound
  • 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 distortion 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 sounds with higher intensity, deeper and richer bass, and clear highs.

Sound Design by DAC Filter

With the ACRO CA1000T, you can pick and choose from seven DAC filters to create your own EQ/style. Design your own sound with the seven DAC filters.

  • Minimum phase (Default): Low latency minimal preringing and low-pass ripple wave
  • Linear Phase Apodizing: Full image rejection by FS/2 to avoid any aliasing, with smooth roll-off starting before 20 kHz wave
  • Linear Phase Fast Roll-Off: Most common filter with clean suppression and high rejection, best for music with high transients. Provides crisp clean highs wave
  • Linear Phase Slow Roll-Off: Low group delay and symmetrical inputs response. Less ringing than Linear Phase, fast roll-off. Punchier bass than LPFR, with clean highs wave
  • Minimum Phase Fast Roll-Off: Minimal preringing, preferred for imaging and soundstage. No aliasing in frequency domain. Stronger bass than Linear Phase, clean high waves
  • Minimum Phase Slow Roll-Off: Nonsymmetrical filter designed to minimize preringing. Strong punchy bass with good transient attacks wave
  • Minimum Phase Slow Roll-Off Low Dispersion: Provides a nice balance of the low latency of minimum phase filters and the low dispersion of Linear Phase filters. Minimal preringing is added to achieve the low dispersion in the audio

Full Balanced Circuit with Dual-Tube

  • Dual Twin Triode KORG Nutube tubes, which were implemented for the first time in Astell & Kern's SP2000T, offering advanced tube sounds.
  • When a product is equipped with a Dual DAC, and one vac
