GUSTARD X26III
Dual ES9039SPRO Chips
The Gustard X26III features dual ES9039SPRO chips for superior digital-to-analog conversion, with one chip dedicated to each channel—left and right—for precise stereo sound. Independent power supplies and grounding for each chip ensure minimal interference, delivering a clean, detailed, and immersive audio experience.
DSP Digital Filter
The DSP Digital Filter utilizes a high-performance solution built on the Analog Devices SHARC digital audio-specific DSP platform. Its primary objective is to reduce audio in-band aliasing noise within the digital domain. By upscaling and shaping the raw digital audio stream, this filter enhances overall sound quality. Key technical features include an anti-aliasing noise algorithm and high-precision 64-bit floating-point operations, ensuring optimal performance and clarity.
FPGA Programmable Logic Chip
The FPGA Programmable Logic Chip incorporates exclusive technologies, including digital integrated circuits with self-constructed logic functions, clock management, 2nd PLL digital shaping, DOP demodulation, and PCM/DSD depop switch. These innovations provide a solid foundation, ensuring excellent sound quality and optimal performance.
GCLK-02 Clock Module
The GCLK-02 is a high-performance clock frequency synthesizer that utilizes advanced PLL (Phase Locked Loop) technology to ensure stability and accuracy of the clock signal. It offers flexible clocking options, allowing users to choose between a local clock source or an external 10MHz clock signal. This design significantly reduces the impact of front-end clock performance on the overall system, minimizing dependence on the performance of front-end audio equipment.
Hybrid IV Conversion and Analog LPF Circuits
The Hybrid IV conversion circuit, designed in parallel to meet the high-current demands of the ES9039SPRO chip, ensures optimal performance. The analog LPF circuits use discrete Class-A components, allowing for precise tuning and greater flexibility compared to integrated circuits. This approach minimizes distortion, offering a warm, natural sound with low noise. By carefully selecting and matching components, the circuits enhance overall sound performance, providing a rich and realistic audio experience.
Completely Self-Developed Network Bridge System in Cooperation with CelAudio
The network bridge system is designed with a focus on music playback, removing unrelated hardware to restore the true nature of the sound. Built on the CelWare 3.x music playback system, it combines optimized hardware and software, with a Linux kernel tailored for I/O performance. This design prioritizes dynamic music playback, minimizing audio data forwarding latency and jitter, and enhancing audio playback capability. The software also manages playback applications and can shut down unused bridge systems to maximize playback efficiency.
USB interface with XMOS XU216
The USB interface features the XMOS XU216 chip, supporting PCM768k and DSD512, ensuring high-quality audio performance with minimal latency.
Independent Power Supply and Signal Integrity
It adopts independent voltage stabilization, multi-stage filtering, and excellent left-right channel separation to ensure no interference. Dual high-quality toroidal transformers supply power separately to digital and analog circuits, achieving complete isolation. Multiple power supply groups work independently to guarantee stable and full power delivery.
