FiiO: WARMER R2R Desktop Tube Buffer & DAC Silver

📌 LAB POINTS

• utilizing R/2R ladder design + high-quality DAC + vacuum tubes, converts digital inputs to smoother, warm-sounding analog signal
• inputs: USB Type-C, coaxial, optical
• desktop R2R tube buffer / digital-to-audio converter w/ 4-tube analog buffer stage
• dual ES9068AS DAC chips independently process left/right channels for a more refined, detailed sound
• 4 x JJ Electronic E88CC vacuum tubes (Slovakia-made, ±28V supply, 10,000hr lifespan) deliver a warm tube-like sound coloration
• mechanical VU meters with LED backlighting
• 46W low-noise linear power supply
• switchable NOS (non-oversampling) and OS (oversampling to 384kHz) modes
• please note: this is a DAC/tube buffer, not a powered amplifier. requires separate amp to power speakers

"The star of the show is FIIO's proprietary, four-way full differential 24-bit R2R DAC, built with a total of 192 high-precision thin-film resistors (48 per channel) boasting 0.1% accuracy and an ultra-low drift of 30ppm. This gives the WARMER R2R its distinctly captivating sound signature." - FiiO
