{"product_id":"fiio-warmer-r2r","title":"FiiO Warmer R2R","description":"\u003cp\u003eThe FiiO Warmer R2R is a desktop digital to analog converter built around a discrete R2R ladder rather than an off the shelf delta sigma chip. The ladder is fully differential and assembled from high precision thin film resistors, 48 per channel, and its output passes through a tube buffer stage running four JJ Electronic E88CC valves. The name describes the intent: the combination is voiced for a fuller, warmer presentation than a conventional desktop DAC.\u003c\/p\u003e\u003cp\u003eTwo mechanical VU meters sit on the front and move with the music rather than being a screen animation. A low noise linear power supply feeds it, digital sources connect over USB-C, optical or coaxial, and it outputs on balanced XLR as well as single ended RCA, so it will drive a balanced or an unbalanced amplifier. A switch selects UAC 1.0 or UAC 2.0 for USB compatibility, with no drivers needed. This is the silver finish.\u003c\/p\u003e\u003cdetails style=\"margin:14px 0 10px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:700\"\u003eSpecs\u003c\/summary\u003e\u003cdiv style=\"padding:8px 2px\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eDesktop R2R DAC with a tube buffer output stage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eConversion\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eDiscrete fully differential 24 bit R2R ladder built from high precision thin film resistors, 48 per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eTube Stage\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eFour JJ Electronic E88CC tubes used as a buffer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eMetering\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eTwo mechanical VU meters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003ePower Supply\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eLow noise linear supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eUSB-C, optical and coaxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eBalanced XLR and single ended RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eUSB Modes\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eSwitchable UAC 1.0 and UAC 2.0, no drivers required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cp\u003eSee pictures for condition.
