Unknown condition makes the price slightly harder to judge, but £87 sits comfortably within the normal market: the median of 54 comparable listings is £79, with the upper quartile at £89. That makes it fair rather than a bargain, and not overpriced—provided the unit is clean, fully working, and includes its 12V power supply.
The K11 remains a very capable compact DAC/headphone amp, offering clean, neutral sound, useful USB, optical and coaxial inputs, RCA pre-out, and plenty of power. Its balanced 4.4mm output is especially useful for harder-to-drive headphones, while the 6.35mm socket suits most everyday setups. At this price, check the display, volume control, both headphone outputs and included accessories; if those are all sound, it is a sensible buy rather than a risky stretch.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
