1. Proprietary Discrete R-2R Module

   R-2R ladder network DAC utilizes resistor-based switching to convert digital signals into analog. The R-2R conversion process is more direct and inherently pure than the modern delta-sigma DACs.

2. 1-Bit DSD

   True 1-Bit DSD D/A Converter with native DSD512 support.

   In DIRECT DSD mode, the DSD signal is routed directly to the 1-bit switching array DAC circuit, completely bypassing PCM conversion.

3. 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.

4. Bridge System

   • The hardware is purpose-built for music playback
   • The system supports software-controlled playback applications and allows deactivation of non-essential bridge processes to maximize playback efficiency

5. Bluetooth 5.0

   • Support: LDAC, AAC, SBC, aptX, LDAC
   • Enables 24-bit/96kHz high-resolution transmission

XMOS

Features the third-generation USB Audio XU316, supporting up to PCM 768kHz and DSD512.

CK01 Clock Module

Delivers femtosecond-grade precision timing for the entire system.

Independent Voltage Regulation

Independent voltage regulation for each circuit group minimizes interference and ensures optimal performance.

Analog Output Driver Circuit

Utilizes a low-impedance design to seamlessly drive various devices while maintaining signal integrity.

• 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.
• 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.
• 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 lays a solid foundation for exceptional sound quality.
• Bridge System ▶️ The hardware is purpose-built for music playback, stripped of all non-essential components to preserve the authentic sound. Running on the dedicated CelWare3.x music playback system, it combines specially designed I/O hardware and software. The system supports software-controlled playback applications and allows deactivation of non-essential bridge processes to maximize playback efficiency.
• XMOS ▶️ Features the third-generation USB Audio XU316, supporting up to PCM 768kHz and DSD512.
• CK01 Clock Module ▶️ Delivers femtosecond-grade precision timing for the entire system.
