{"type":"firestarter.listing","listing":{"id":"lst_o6OL3NPr","product_name":"GUSTARD X26 III Dual ES9039SPRO Digital to Analog Convertor (DAC)","category":"DAC (Digital-to-Analog Converter)","description":"\n Fully-balanced desktop DAC with dual ES9039SPRO chips \n\nThe Gustard X26 III is a flagship DAC designed for exceptional detail, spacious imaging, and modern connectivity in one refined unit. Building on the X26 Pro, it features twin ES9039SPRO DAC chips, a precision FPGA-controlled clocking system, and a discrete Class‑A analog stage for natural warmth. With integrated network streaming—including Roon, AirPlay, and UPnP support—and fixed balanced and single‑ended outputs, it’s a versatile centerpiece for high‑resolution audio systems.\n\nDual ES9039SPRO DAC Chips\n\nEach stereo channel is powered by its own ES9039SPRO chip, complete with independent power rails. This architecture maintains superior channel separation, reduces crosstalk, and enhances imaging precision, helping instruments and voices occupy clear, distinct spaces in the soundstage.\n\nBuilt-in Network Streamer & USB Interface\n\nEquipped with LAN (100/1000 Mbps) supporting Roon/Bridge, AirPlay, UPnP, Spotify, HQPlayer NAA, and more via CelWare 3.x, the X26 III can directly access streaming services or your local library. A USB-B port driven by XMOS XU216 supports high-res PCM768 and native DSD512.\n\nPrecision Clocking & FPGA Control\n\nFeaturing the GCLK‑02 clock module and a femtosecond-grade clock generator, the DAC minimizes jitter for cleaner audio timing. A powerful FPGA handles PLL shaping, DOP decoding, digital filtering, and depop control—key steps in ensuring smooth signal flow. \n\nAnalog Class-A Discrete Filter\n\nFollowing the DAC chips, a discrete Class-A analog low-pass filter—designed specifically around the ES9039SPRO's characteristics—delivers natural warmth and low noise. This arrangement supports a vivid but accurate tonal balance. \n\nFixed-Balanced & Single-Ended Outputs\n\nThe X26 III provides fixed-volume outputs via RCA (2.5 V RMS) and XLR (5.1 V RMS), both with 100 Ω impedance, ideal for integration with external preamps or power amplifiers. \n\nCompact, Efficient Build\n\nEncased in a ","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gustard-gustard-x26-iii-dual-es9039spro-digital-to-analog-convertor-dac-1177017294.webp?v=1774435660","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gustard-gustard-x26-iii-dual-es9039spro-digital-to-analog-convertor-dac-1177017290.webp?v=1774435660","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gustard-gustard-x26-iii-dual-es9039spro-digital-to-analog-convertor-dac-1177017292.webp?v=1774435660","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gustard-gustard-x26-iii-dual-es9039spro-digital-to-analog-convertor-dac-1177017291.webp?v=1774435660","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gustard-gustard-x26-iii-dual-es9039spro-digital-to-analog-convertor-dac-1177017293.webp?v=1774435660"],"price":1599.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.458Z"},"share_url":"https://firestarter.network/l/lst_o6OL3NPr","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
