The DSDAC 1.0 Deluxe is a technically very advanced DAC which means absolutely nothing if it doesn’t add up to something special sonically. The sonics easily match its technical ability with excellent detail and resolution that doesn’t present itself as sounding hyped in any way but serves the music. It is a natural sounding, smooth and musically engaging performer. Then, with the various uprising options, the sonic differences allow you to tweak to your system or preferences. All PCM or DSD digital content can be upscaled to DSD128, DSD256, DSD512 or DSD1024. It also uses an outstanding Muses volume control, so can be either used fixed mode or variable as a DAC/preamp with no degradation.
This DAC is a new product which was developed on the basis of the standard model by optimizing the clock system and making major modifications to the circuit. It is different from an ordinary DAC. Its high-precision DSD frequency rising algorithm solves the playback problem of DSD64 perfectly. The synchronous direct clock technology enables the built-in femtosecond clock to be transmitted to the shift register directly without any process, so that the femtosecond performance can directly improve the analogue signal quality. The clock blocking technology can isolate the clock of the source device completely, so that the clock of the source no longer becomes a factor affecting the sound quality.
Differences between the DSDAC1.0 deluxe and standard model:
- The clock system of the deluxe model has higher performance with RMS jitter as low as 100 femtosecond.
- Digital & analogue circuit is more sophisticated with many advanced components used.
- Fully optimized power supplies. Independent transformers are used for analogue and digital.
- Upgraded aesthetics
The DSDAC1.0 Deluxe is an audio DAC based on DSD audio technology. It took five years to develop. It has three advanced audio technologies.
- high-precision algorithm for DSD frequency uprising
- synchronous direct clock
- clock replacement technology
Cen.Grand has resolved the DSD technical barriers producing one of the top DSD DACs available.
R&D Background
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.
R&D History
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.
Core Technology
DSDAC1.0 Deluxe’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.
Preamp Mode
The Deluxe model can also be used as a preamplifier providing a maximum 5db gain for the input signal. In preamp mode the function of DAC is not available and it is strictly a preamp for its XLR and RCA inputs.
