Descriptions:

> Proprietary Discret 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.

> 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 singal is routed directly to the 1-bit switching array DAC circuit, completely bypassing PCM conversion. Using pure hardware processing, the system directly translate the DSD bitstream into analog, preserving the full dynamic range and detail of the original pulse modulation.

> FPGA
> Employing a field-programmable gate array (FPGA), this custom-configured digital integrated circuit allows flexible implementation of logic functions, includng clock management and digital shaping. Integrated with exclusive technologies such as DoP demodulation and PCM/DSD depop switching, the FPGA lays a solid fondation for exceptional sound quality.

> Bridge System
> The hardware is purpose-built for music playback, stripped of all the non-essential components to preserve the authentic sound.
> Running on dedicated Celware 3.x music playback system, it combines specially designed I/O hardware and software. The underlying Linux kernel is deeply optimized for audio I/O, enabling dynamic music playback and hardware-priority scheduling. This minimizes audio data forwarding latency and jitter while enhancing playback capability.
> The system supports software-controlled playback applications and allow deactivation of non-essential bridge processes to maximize playback efficiency.

> CK01 Clock Module
> Delivers femtosecond-grade precision timing for the entire system,

> Independent Voltage Regulation For Each Circuit Group Minimizes Interference And Ensures Optimal Performance.

> Analog Output Driver Circuit
> Utilizes low-impedance design to seamlessly drive various devices while maintaining signal integrity.
