{"product_id":"denafrips-venus15th-b","title":"DENAFRIPS VENUS 15TH R-2R DAC","description":"\u003cp\u003eThe \u003cstrong\u003eDenafrips Venus 15th\u003c\/strong\u003e is a reference true-balanced digital-to-analogue converter (DAC) built around a proprietary discrete R-2R ladder architecture and 6-bit DSD FIR filtering network. Featuring precision-matched 0.005% thin-film resistor arrays, the unit incorporates an FPGA-controlled adaptive FIFO buffer and reclocking system powered by dual Oven-Controlled Crystal Oscillators (OCXO) running at 45.1584 MHz and 49.152 MHz. Digital and analogue stages are fully isolated physically to maintain a low noise floor.\u003c\/p\u003e\n\n\u003cp\u003eHoused in a heavy-gauge anti-resonant aluminium chassis, the power supply section utilizes an encapsulated multi-stage linear architecture featuring two single-crystal copper toroidal transformers (one 80W and one 250W unit). The DAC accepts digital signals up to PCM 1536 kHz and native DSD1024 over USB and I²S interfaces, alongside dual AES\/EBU, coaxial, and optical TOSLink inputs. Analogue output is delivered via gold-plated single-ended RCA and true-balanced XLR terminals.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; PROPRIETARY TECHNOLOGIES\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eTrue Balanced 26-Bit R-2R \u0026amp;
