Product description The Gustard R30 audio R-2R DAC features a fully discrete R2R ladder network, which completes signal conversion through precise switching of resistors. It supports native 1-bit DSD decoding, capable of retaining the details and dynamics of high-resolution audio to meet audiophiles' pursuit of lossless sound quality. Equipped with an FPGA-based clock management system, it works in conjunction with an internal OCXO and an external clock input interface. The discrete components form a Class-A analog output stage, and it also includes a new independent digital filter, offering NOS mode and three different digital filter options with distinct characteristics.
Users can flexibly switch according to different music styles and personal listening preferences. It is equipped with a passive preamplifier and analog volume control function. The core architecture and peripheral configurations work in synergy, making the R30 a high-end decoder with a unique sound style, high resolution, and practical attributes, capable of restoring the texture of music. It is also a streaming DAC. Fully discrete R-2R ladder DAC Native DSD1024 decoding via IIS input Three different digital filter modes FPGA-based clock management system External 10MHz clock input interface Discrete Class-A analog output stage Network Streaming decoder True 1-bit DSD decoding The R30 employs a discrete R2R ladder to directly translate digital signals into analog audio.
This approach necessitates meticulous resistor pairing and accuracy, resulting in a more natural and lifelike audio reproduction. Three PCM filter modes are provided: Linear Sharp, Minimum Slow, and Super Slow. Utilizing multi-order adaptive algorithms, these modes perform intelligent upsampling of digital audio signals while precisely reducing noise, delivering a purer and more natural sound reproduction. Utilizing a proprietary digital integrated circuit capable of constructing custom logic functions, including clock management, secondary PLL digital shaping, DOP demodulation, and PCM/DSD depop switching, a solid foundation for exceptional sound quality is established. The GCLK-02 clock module employs advanced PLL technology, achieving 1Hz-level locking precision to deliver ultra-high-precision clock signal processing capabilities. The external connection of a high-quality 10MHz clock further enhances audio quality. Multi-stream ready Access the bridge instantly via the R30-only portal. LAN Input, Streamer DAC Network Bridge Dedicated to HiFi Music R30 features a custom CelWare network bridgelower jitter, seamless streaming from any source.
Bit-perfect stream: PCM768 kHz & DSD512 native, lossless to the R-2R ladder. Discrete Class-A LPF, custom-trimmed for R-2R DACsevery component individually tuned for finer frequency response and subtle sonic shading. True-1Bit DSD DACthe R30 natively handles DSD1024, delivering 1, 024 times the data density of CD. In DIRECT DSD mode the 1-bit switching array decodes the stream directly, bypassing PCM entirely, so micro-detail and timing integrity are preserved. Built around an SC-cut crystal, the OCXO clock delivers exceptional thermal stability, stress resistance, and pinpoint accuracy. The R30 also accepts an external 10 MHz clock input for easy system synchronization. The USB input apots XMOS XU216 interface, decoding PCM768k and DSD512. Deliver pristine, reference-grade audio decoding.
