Special Features

  • 【Custom-Designed Discrete R-2R Module】 The core of the Gustard R30 DAC is based on a discrete 27-bit R2R architecture, using a ladder resistor network for signal processing instead of a traditional conversion chip. This method achieves fully analog conversion without complex digital interpolation. Therefore, it can also be used as a passive analog preamplifier. Switching to pure bypass mode allows it to be used as a DAC, or directly connected to active monitor speakers or a power amplifier.
  • 【True-1 Bit Decoding】 The R30 Hone desktop DAC natively supports DSD1024, meaning it can handle data densities 1024 times higher than CD audio. In DIRECT DSD mode, the bitstream completely bypasses PCM conversion, being decoded directly through a 1-bit switching array, thus preserving fine detail and temporal integrity.
  • 【OCXO External Clock Input and GCLK-02 Module】 The OCXO clock works in conjunction with the GCLK-02 clock module, a high-performance clock frequency synthesizer employing advanced phase-locked loop (PLL) technology to ensure the stability and accuracy of the generated signal. Designed to use either a local clock source (OCXO in this example) or an external 10MHz clock signal, this module provides a high-quality and flexible clocking solution.
  • 【A Network Bridge Built for Music】 The Network Streaming DAC's CelWare 3.x software is based on an audio-optimized Linux kernel and supports multiple protocols including Roon Bridge, AirPlay, HQPlayer NAA, UPnP, and Spotify. Users can enable or disable these features simply by entering the address "//x30.local" in their browser.
  • 【Gustard's FPGA】 The R30 DAC utilizes Gustard's proprietary FPGA, responsible for signal reconstruction and advanced digital stream management. It handles clock signal distribution and processing, PLL (Phase-Locked Loop) shaping, DoP demodulation, and switching noise suppression in PCM and DSD signals. This integration enables precise control over each stage, ensuring stable and optimized conversion.
  • 【Class A Analog Circuitry】 Instead of integrated operational amplifiers, the Gustard R30 uses discrete Class A low-pass filter stages, allowing each component to be tuned individually. This translates to better control over frequency response, harmonic characteristics, and transient response.
