The FiiO Warmer R2R external DAC uses a fully differential proprietary 24-bit R2R matrix consisting of 192 thin-film precision resistors with a tolerance of 0.1 percent and a temperature drift of 30 ppm. This circuit is fundamentally different from typical delta-sigma chips and, according to the manufacturer, is designed to provide a more harmonious, detailed sound.
