4 Gain Stages And an output power of up to 15Vrms for the perfect Head-Fi Setup
The ACRO CA1000T sets the stage for the perfect Head-Fi setup with its 4-level gain options and an impressive up to 15Vrms output. Achieving an ideal match between the source and the receiving device is crucial for delivering impeccable sound, especially when dealing with intricate IEMs and demanding headphones.
This audio powerhouse supports four gain levels, enabling users to tailor the output to the specific characteristics and sound profiles of their headphones. The flexibility of these gain settings allows for precise adjustments, ensuring an optimal and customized volume output. With a robust up to 15 Vrms output, it effortlessly handles high-impedance headphones with grace.
Enhancements to the electrical capacity of the output ports add stability when accommodating devices with varying impedances at different gain levels. The separate controls for balanced and unbalanced volumes optimize electricity flow, effectively minimizing noise and maximizing sound quality.
In the realm of audio perfection, the ACRO CA1000T promises an immersive experience, delivering optimal device performance and pure, soul-stirring sound.
Complete Balanced Circuit with Dual-Tube Design
Incorporating dual Twin Triode KORG Nutube tubes, a technology initially introduced in our award-winning SP2000T, the ACRO CA1000T delivers an advanced tube sound experience.
In cases where a product is equipped with a Dual DAC and a single vacuum tube, a distinct circuit becomes necessary to convert the signal to a balanced state just before reaching the output terminal. This configuration involves a process to transform an unbalanced signal into a balanced one, a step during which noise may be amplified.
In contrast, the CA1000T features a fully balanced circuit, utilizing two vacuum tubes to independently separate the left and right channels, resulting in more natural and smoother audio tones.
Whether in Tube AMP mode or OPAMP, both modes deliver a robust 15 Vrms output, while the headphone ports provide an opportunity to savor the distinctive tones of vacuum tubes without any restrictions.
TRIPLE AMP SYSTEM: The Evolution in AMP Technology
The ACRO CA1000T goes beyond conventional AMP Mode selection based on music genres. Choose from TUBE AMP mode, OP AMP mode, or the innovative HYBRID AMP mode.
OP AMP mode leverages Astell&Kern’s AMP technology expertise, delivering exceptional clarity and dynamic sound. TUBE AMP mode, on the other hand, imparts a distinctively warm and musical audio signature.
Introducing a pioneering feature for digital audio players, the HYBRID AMP mode elevates the resolution and clarity of the existing TUBE AMP mode, revealing intricate musical details. By blending the benefits of retro analog performance with high-resolution output, HYBRID AMP mode introduces a novel tonal characteristic, providing a unique auditory experience.
Explore the unparalleled sound enhancements offered by this advanced AMP technology. The TRIPLE AMP SYSTEM in the ACRO CA1000T sets a new standard for audio amplification, allowing you to tailor your listening experience to your preferences.
Tailored Design for Microphonic Noise Reduction
Our ACRO CA1000T features a specialized custom design crafted to minimize microphonic noise originating from external shocks and vibrations.
In addressing the inherent structural challenge of vacuum tubes, susceptible to generating microphonic noise even from the slightest shocks or vibrations, we engaged in iterative design development. Rigorous testing and prototyping led to a solution where both sides of the vacuum tube are securely enveloped in flexible silicon covers. This design minimizes the impact of shocks, and a magnetic force is strategically employed to physically isolate the tube from the PCB. The result is enhanced stability and isolation, ensuring optimal performance when the tube is in operation.
Astell&Kern remains dedicated to meticulously designing these minute elements and nuances that set our products apart, contributing to the unparalleled distinction in sound compared to competitors.
