K2 / Synchronous Clock Built-In Technology
K2 clock synthesizer Synchronous clock implantation technology synthesize local femtosecond clock or external 10M into audio master clock. Instead of the front-end clock source, DAC only uses local femtosecond clock or external 10M constant temperature clock source synthesis as the main clock. Therefore, the impart of the front-end signal source clock performance on the decoding link is greatly reduced. USB/IIS/AES/Coaxial/Optical/Bluetooth interface can also enjoy the performance improvement brought by synthesizer.
Excellent Performance ES9038pro Chip
Gustard X26 Pro features two pieces of ESS company flagship chip ES9038pro for decoding, each of that has a separate chip, meaning it can supply independent power completely and ground for excellent performance.
Independent R&D of DSP Digital Filter
The HiFi Audio Decoder adopts the high-performance digital filter solution which was developed on the Analog Device SHARC digital audio dedicated DSP platform. It is also equipped with a self-developed high-performance anti-aliasing noise algorithm. High-precision floating-point 64-bit operations are used in the key digital signal processing links. In order to reduce the aliasing noise in the digital domain audio band and achieve better sound quality performance, the high-performance decoder upscales and shapes the original digital audio stream signal.
Analog Low Pass Filter Circuit
Each discrete device only needs to consider its own performance without any restrictions, so it can perform fully every single component. The use of discrete devices is more flexible, not only because it is not integrated in the chip like integrated circuits and cannot be separated and changed but also it is more developable and relatively controllable for the distortion part. It can bring more variable sound styles to different decoding architecture.
CPLD Programmable Logic Chips
Digital integrated circuits are self-constructed with logic functions, clock management, 2nd PLL, digital shaping, DOP decoder, PCM/DSD depop switch and other exclusive technologies. All of these have laid a solid foundation for excellent sound quality.
