Against the obvious alternative of a standard FiiO K11, £110 is a fair-to-good price for the R2R version. Your 60-listing comparables put the median at £99, with the middle 50% spanning £92–£111, so this sits near the top of the normal range rather than looking overpriced. Given the unknown condition, it is fair rather than an outright bargain.
The K11 R2R is well regarded as an unusually capable compact DAC/headphone amp: its resistor-ladder DAC offers selectable NOS and oversampling modes, while balanced 4.4mm output provides plenty of power for demanding headphones. USB, optical, coaxial and RCA/pre-out connections make it versatile on a desk or in a system. At £110, check that the display, volume control and both headphone outputs work, and confirm the power supply and remote—if included.

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.
