FIIO Warmer R2R Desktop Tube Buffer & DAC/Amp Fully Differential 24-Bit Resistor Ladder, Dual VU Meters, 46W Linear Power Supply, USB/Optical/Coaxial Inputs, RCA/XLR Output (Silver)

Four JJ Electronic E88CC Tubes for Sweet, Natural Tube Warmth Equipped with four brand-new JJ Electronic E88CC tubes imported from Slovakia, powered by a true ±28V supply. With up to 10,000 hours of lifespan, the tube buffer circuit is carefully optimized to deliver sweet, natural, richly layered tube tonality. FIIO Self-Developed Fully Differential 24-Bit R2R DAC with True Analog Flavor Featuring FIIO’s in-house 4-channel fully differential complementary 24-bit R2R resistor ladder DAC. Built with 192 precision thin-film resistors (0.1% tolerance, 30ppm low temperature drift), WARMER R2R delivers an unmistakably analog, musical sound signature. Dual-Channel LED-Backlit True Mechanical VU Meters for Retro Vibes Classic warm backlit stereo VU meters, driven by a dedicated IC. The needles dance with your music, adding a nostalgic, immersive visual experience to your HiFi setup. 46W Low-Noise Linear Power Supply for a Pure, Black Background Powered by a 46W low-noise “O-core” audio-grade linear transformer. Its high efficiency, reduced eddy current, and even magnetic distribution ensure minimal leakage and deliver clean, stable power for superior sonic purity. Rich Inputs/Outputs for Flexible HiFi System Integration More than a DAC—it's an R2R DAC with tube amplification. Includes USB/Optical/Coaxial digital inputs plus RCA and XLR line outputs, giving you versatile connectivity options to integrate seamlessly with your HiFi system.
