This is an ambitious ask rather than a deal: £94 sits above the 75th-percentile comparable price of £89 and well above the £78 median from 59 recent listings. With the condition unknown, there is no obvious value advantage unless it is exceptionally clean, complete, or includes desirable extras.
The K11 remains a very capable compact DAC/headphone amplifier, with USB, optical and coaxial inputs, RCA line out, a useful display, and both 6.35mm single-ended and powerful 4.4mm balanced outputs. It is well regarded for low noise, flexible connectivity, and enough power for most headphones, but at £94 the unit should be demonstrably excellent: confirm the 12V power supply, test both headphone outputs and the display, and ideally negotiate closer to £85–£89.
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.
