Product Description
Along with multiple digital and analog input options, such as digital RCA coaxial, 4.4mm, USB-C, and 3.5mm optical, the ACRO CA1000T sports onboard Bluetooth 5.0 with Qualcomm aptX HD technology for high-quality LDAC streaming, as well as dual-band Wi-Fi, ensuring that you will always have a reliable way of feeding audiophile audio through your DAC. The onboard 720P touchscreen display makes operation and selection of the many settings a breeze, and the internal lithium-ion polymer battery can be charged via USB-C for premium quality audio anywhere. Choose between four levels of gain, three amplification architectures (op-amp, tube, or a combination), and much more, for the ultimate high-fidelity listening experience, whether in your home, on-the-go, or even onstage.
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 and clear highs.
- Minimum Phase (Default)—Low latency, minimal preringing and low-pass-band ripple
- Linear Phase Apodizing—Full image rejection by FS/2 to avoid any aliasing, with smooth roll-off starting before 20 kHz
- Linear Phase Fast Roll-Off—Most common filter with clean suppression and high rejection, best for music with high transients and provides crisp, clean highs
- Linear Phase Slow Roll-Off—Low group delay and symmetrical inputs response. Less ringing than fast roll-off with punchy bass and clean highs
- Minimum Phase Fast Roll-Off—Minimal preringing, preferred for imaging and soundstage. No aliasing in frequency domain and sports strong bass with clean highs
- Minimum Phase Slow Roll-Off—Nonsymmetrical filter designed to minimize preringing. Strong, punchy bass with good transient attacks
- Minimum Phase Slow Roll-Off Low Dispersion—Provides a nice balance of low latency and low dispersion
The CA1000T, however, offers a completely balanced circuit that separates left and right channels with two twin triode KORG Nutube vacuum tubes, creating even more natural and softer sounds. Both Tube Amp and Op-Amp modes provide a powerful 15 Vrms output, and the headphone ports allow you to enjoy the unique sounds of vacuum tubes without any limitations.
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.
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.
Playback Mode

And with up to a 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.
