Cen.Grand DSDAC 1.0 SuperClock Edition – Reference-Grade DSD DAC with No Compromises
The Cen.Grand DSDAC 1.0 SuperClock Edition is a high-end digital-to-analog converter (DAC) designed exclusively for native DSD processing, abandoning traditional PCM-based conversion methods. Unlike conventional DACs, it does not use a standard DAC chip, instead relying on a custom FPGA-based architecture and discrete circuit solutions to achieve unparalleled sound quality.
The SuperClock model is the most advanced, ultra-low jitter edition in the DSDAC 1.0 series, exceeding the expectations of even the most demanding audiophiles.
Key Features
1. FPGA-Based Native DSD Processing – No DAC Chip
The SuperClock Edition eliminates the need for a pre-manufactured DAC chip, relying instead on a dedicated FPGA-based digital-to-analog conversion system. This programmable logic circuitry executes high-resolution signal processing algorithms, allowing full control over audio data for a natural, analog-like sound signature.
2. Advanced DSD Upscaling Technology – Up to DSD1024
This model can real-time upscale any incoming digital signal—whether PCM or DSD64—to DSD1024. The proprietary high-precision algorithm ensures artifact-free conversion, while shifting high-frequency noise outside the audible range, resulting in cleaner, more natural sound reproduction.
3. Ultra-Precise Clock Technology – Only 100 Femtoseconds Jitter
The SuperClock Edition earns its name from its exceptionally precise internal clock system.
With an RMS jitter value of only 100 femtoseconds, it delivers superior timing accuracy through three crucial innovations:
- Synchronous Direct Clock Technology: The femtosecond-grade clock feeds directly into the conversion chain, eliminating jitter-induced distortion
- Clock Blocking Technology: Fully isolates itself from external source clocks, ensuring consistent audio quality regardless of the playback system
- Precision DSD Upsampling Algorithm: Controls signal processing to preserve the original character of the source material
High-Level Compatibility – USB & SPDIF Inputs
The SuperClock Edition supports multiple digital input sources, allowing effortless integration into high-end audio systems:
- USB-B Input (XMOS XU208 Chipset): Native DSD support up to DSD512, with galvanic isolation for noise reduction
- SPDIF Inputs: AES/EBU, optical Toslink, coaxial RCA, and BNC – supporting PCM 24-bit/192 kHz and DSD64 (DoP)
Analog Outputs & Precision Volume Control
The SuperClock Edition is distinguished by its high-end output section:
- Balanced XLR Output: 5.0V RMS
- Unbalanced RCA Output: 2.5V RMS
- Digital Volume Control: Fine-step adjustment, ranging from -70 dB to 0 dB
This configuration enables direct connection to active speakers or power amplifiers, even without a separate preamp.
Premium Build Quality & Development Philosophy
The SuperClock Edition is the result of five years of intensive research and development at Cen.Grand.
- The chassis is precision-machined aluminum, available in classic black and silver finishes
- The internal circuitry was refined through more than twenty prototype iterations, ensuring flawless signal integrity and distortion-free performance
