This is a fair ask, sitting well within the normal used market: GBP £87 is just above the £79 median from 56 comparable listings, but still below the £88 upper quartile. It is not a bargain, though it looks appropriately priced if the unit is clean and complete.
The K11 remains a particularly capable compact DAC/headphone amp, with clean neutral sound, USB, optical and coaxial inputs, RCA line-out, three gain settings, and useful 6.35 mm and balanced 4.4 mm headphone outputs. Its balanced stage offers substantial power for demanding headphones, while the straightforward display and multifunction knob make it pleasant to live with. At this money, check that the external power supply is included and test both headphone outputs, the volume control, and RCA output; otherwise, this is a sensible, versatile buy rather than an inflated listing.

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.
