{"type":"firestarter.listing","listing":{"id":"lst_VDE_v6oN","product_name":"Apos x Community Druid R2R DAC","category":"DAC (Digital-to-Analog Converter)","description":"The old ways are calling\nBuilt around a fully-discrete R2R ladder, the Druid converts digital data into analog waveforms through a precise network of resistors rather than a high-speed modulation process. Each resistor contributes a tiny part of the signal, forming a sound that feels natural, human, and grounded in something older than silicon. This DAC does not compute. It communes. \nThe first R2R DAC with swappable op-amps\nThe idea came straight from the community: give the upcoming R2R DAC swappable op-amps. What started as a suggestion turned into one of our favorite parts of the Druid. The open-chassis design made perfect sense for it: no case to crack open, no hidden screws, just clear access to the sockets. We’re glad the community pushed us on this one, because it made the Druid into an even more satisfying product. Need help swapping op-amps? Note: Given the Druid's compact design, no single op-amp may draw more than 10mA. Exceeding this risks overheating, unwanted noise, or potential damage to the unit.\n\nTuned by ear\nInside are three swappable op-amps: two for the balanced XLR outputs and one for the single-ended 3.5mm. When it came to choosing the stock op-amps, we didn't start with any particular sound or spec sheet advantage in mind—just a price point and the goal of being wowed. We tested everything we could get our hands on, and the Texas Instruments LM4562NA/NOPB stood out immediately. It handled the midrange with an easy, natural smoothness that made vocals and acoustic instruments feel alive. Especially paired with the Gremlin, it brought a smile to our faces. \nXLR balanced outputs\nFor those running balanced chains, the Druid provides a 4V XLR output that delivers all the current and control you’d expect from a fully differential stage. The result is lower noise, higher headroom, and tighter channel separation: everything you want when driving balanced amplifiers or powered monitors. \n3.5mm single-ended output\nBecause PCB space is sacred, the Druid","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1211883442.png?v=1766082036","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630735.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630736.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630728.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630734.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1201740330.png?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630737.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630729.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200471082.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1201718758.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1201718759.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1201740331.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1202187177.png?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630731.jpg?v=1766072887","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-dac-digital-to-analog-converter-apos-x-community-druid-r2r-dac-1200630730.jpg?v=1766072887"],"price":160,"currency":"USD","in_stock":true,"inventory_qty":119988,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.364Z"},"share_url":"https://firestarter.network/l/lst_VDE_v6oN","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
