{"product_id":"gustard-r30","title":"Gustard R30","description":"\u003cp\u003eThe Gustard R30 is a flagship fully-discrete R2R network streaming DAC built around 27-bit resistor ladder architecture with an integrated OCXO oven-controlled crystal oscillator. It combines USB, I²S, coaxial, AES\/EBU, optical and network streaming inputs with balanced XLR and single-ended RCA outputs for reference-grade digital-to-analog conversion.\u003c\/p\u003e\n\u003ch2\u003eWhy it stands out\u003c\/h2\u003e\n\u003ch3\u003eFully Discrete 27-Bit R2R Architecture\u003c\/h3\u003e\n\u003cp\u003eEvery signal-path component is an individual surface-mount resistor, capacitor and op-amp hand-selected by Gustard engineers — no integrated DAC chip.
