This US$125 listing for the FiiO K11 R2R is a strong deal, sitting below the 25th percentile of recent used comps where the median is US$134. You are effectively paying less than the floor of the typical asking-price range (US$125–US$148), making it an excellent bargain for a unit that retails new between US$159 and US$190.
The K11 R2R is widely celebrated as the only R2R DAC/amp under US$200, offering a discrete resistor-ladder architecture that delivers a warmer, more analogue-feeling sound than mainstream delta-sigma chips. It pairs this distinct tonal character with a robust 1,400mW balanced amplifier and a 4.4mm jack, making it a versatile desktop powerhouse for jazz, classical, and acoustic music. At this price, it’s a clear buying opportunity for anyone seeking authentic R2R performance without boutique costs.
