US$85 is a strong deal here: it sits below the 25th percentile of recent used listings at US$99 and well under the median of US$105, so this is priced to move rather than stretch. For a compact desktop DAC, that makes it a very attractive buy if the unit is clean and functional.
The K11 is well-liked for giving a lot of sound quality, power, and connectivity for the money, especially as a simple one-box desktop upgrade from onboard audio or older entry-level gear. At this price, the real upside is getting a current, well-regarded DAC without paying new-retail money; just confirm the power supply, USB cable, and front-panel controls all work properly, since those matter more than cosmetic wear.
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.
