This £105 ask for the used FiiO K11 R2R is a fair price that sits just above the median of £100 for 36 recent comparable GBP listings, comfortably within the £93–£110 typical range. It is not a bargain, but it is certainly not ambitious, making it a solid entry point for a buyer who wants this specific R2R DAC/amp without hunting for a sub-£93 outlier.
The K11 R2R is well-regarded for bringing genuine resistor-ladder (R2R) sound to a budget desktop price, delivering clean PCM up to 384kHz/24-bit and DSD256 decoding with no oversampling. It pairs a versatile USB-DAC with a capable amplifier offering up to 1.3W into 32Ω balanced, making it a strong daily driver for a wide range of headphones. At this fair price, it’s a worthwhile buy if the unit is clean and includes original accessories.

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. From modest beginnings, the company expanded into a 15,000-square-meter industrial complex by 2022, solidifying its role as a prolific developer of music-centric electronics.
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.
