Cen.Grand DSDAC 1.0 Super Clock DAC

The Cen.Grand DSDAC1.0 SC (Super Clock) is a high-performance audio DAC based on DSD theory. Original technologies set it apart from an ordinary DAC. It does not use conventional chips for DA conversion but FPGA and discrete components for digital processing. The DSDAC1.0 SC can increase the frequency of all input data including PCM or DSD64 to DSD1024. If the input data is higher than DSD128, you can also output it directly without increasing. The DSD frequency rising algorithm is a very complex mathematical process. The DSDAC1.0 did an excellent job, however, the super clock model takes performance much further.

The DSDAC1.0 SC is an audio DAC based on DSD audio technology.  It took five years to develop.  It has three advanced audio technologies.

DSD audio coding is highly regarded despite technical barriers, captivating music enthusiasts worldwide. SACD's use of DSD64, due to storage limitations, introduces lower accuracy and out-of-band noise, leading many SACD players to convert DSD64 to PCM, diminishing DSD's advantages. Advancements in DSD coding and FPGA technology have enabled an increase in DSD frequency, enhancing DA accuracy and noise filtering. In this process, the frequency of out of band noise is pushed up and then is easily filtered out.

DSD technology required extensive independent research to develop a high-precision frequency rising algorithm. Innovations in clock management introduced "synchronous direct clock" and "clock blocking" techniques. Analogue circuit design is critical, with the DSDAC1.0 team refining its architecture over a year to achieve reference-level DAC performance.

DSDAC1.0 SC's foundation is a high-precision frequency rising algorithm, addressing complex mathematical challenges. Its Synchronous Direct Clock Technology sends femtosecond clock signals directly to the shift register, preventing jitter degradation. Clock Replacement Technology eliminates reliance on the clocks of connected sources, ensuring consistent DAC performance. The DAC supports up to native DSD512 through USB and DSD64 via SPDIF in DOP with XMOS integration for ground isolation.
