This is a fair ask, rather than a bargain: GBP 89 sits just above the recent comparable median of GBP 78 and narrowly clears the 75th percentile of GBP 88. It is therefore a touch strong for an unknown-condition example, though not meaningfully overpriced if it is clean and complete.
The K11 remains a very capable compact DAC/amp, with USB, optical and coaxial inputs, RCA line output, three gain levels, and both 6.35 mm single-ended and 4.4 mm balanced headphone outputs. Its neutral, clean presentation and substantial balanced-headphone power make it versatile with everything from sensitive IEMs to demanding full-size headphones. At this money, confirm the screen, volume control, outputs and power supply are all sound; with tidy condition and original accessories, GBP 89 is defensible, but a little negotiation would make it properly attractive.
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.
