• 【Proprietary Discrete R-2R Module】 R-2R ladder network DAC utilizes resistor-based switching to convert digital signals into analog. Compared to modern delta-sigma DACs, which rely on high-frequency 0/1 switching, the R-2R conversion process is more direct and inherently pure, delivering a more natural sound quality. However, this architecture demands extremely high precision in the resistor network. Achieving superior performance not only involves significant cost but also requires a high level of technical expertise.
• 【FPGA】 Employing a field-programmable gate array (FPGA), this custom-configured digital integrated circuit allows flexible implementation of logic functions, including clock management and digital shaping. Integrated with exclusive technologies such as DoP demodulation and PCM/DSD depop switching, the FPGA lavs a solid foundation for exceptional sound quality.
• 【1-Bit DSD】 True 1-Bit DSD D/A Converter with native DSD512 support. This is equivalent to 8x oversampling of SACD-standard DSD64 and 512x the data density of CD format. In DIRECT DSD mode, the DSD signal is routed directly to the 1-bit switching array DAC circuit, completely bypassing PCM conversion. Using pure hardware processing, the system directly translates the DSD bitstream into analog, preserving the full dynamic range and detail of the original pulse modulation.
• 【CK01 Clock Module】 Delivers femtosecond-grade precision timing for the entire system.
• 【Analog Output Driver Circuit】 Utilizes a low-impedance design to seamlessly drive various devices while maintaining signal integrity.
