This £100 listing is a strong deal, sitting well below the 25th percentile of £93–£110 established by 36 recent GBP comparables, with the median used asking at £100. While new and B-stock units typically range from £150 to £176, this price represents genuine value for a model that remains the current generation R2R option without a direct successor yet diluting demand.
The FiiO K11 R2R is highly regarded for bringing resistor-ladder DAC sound to a budget price, offering transparent audio with adaptive impedance that handles everything from 8 Ω to 350 Ω transducers effectively. Its 660 mW output into 16 Ω via the 1/4" jack provides ample drive for most headphones, and the inclusion of PCM 32bit/384 kHz and DSD 256 decoding ensures modern compatibility. At £100, this is a clear buying opportunity for enthusiasts seeking authentic R2R performance without the usual premium.

Fiio, founded in 2007 in Guangzhou, China, emerged as a specialist in portable audio gear, initially crafting components like speakers for brands such as Meizu before launching its own lineup. The name blends "Fi" from hi-fi fidelity with "iO" symbolizing digital one's and zeros, evoking authentic sound and modern convenience, while its Chinese rendering "飞傲" conveys innovative vitality.

The brand excels across a broad spectrum of portable and desktop audio categories, with flagship strengths in high-resolution digital audio players (DAPs), USB DACs, portable headphone amplifiers, and in-ear monitors. Its portfolio also encompasses cables, desktop amps, and select speakers, prioritizing versatile, high-performance solutions for on-the-go and home listening without venturing into turntables or large-scale hi-fi systems.
Fiio occupies a commanding mid-tier position in the global audiophile market, renowned for delivering premium sound quality at accessible prices that punch above their weight. Praised by enthusiasts for reliability and value, it appeals to discerning buyers seeking refined portable setups over luxury excess, backed by worldwide distribution and a track record of user-acclaimed innovations.
