At US$85, this sits below the 25th percentile of the recent used market, which makes it a strong deal rather than just a fair one; against a median of US$105 and a 75th percentile of US$119, the asking price has real room to be attractive. It is not absurdly low, but it is clearly buyer-friendly for a current desktop DAC/amp.
The K11 is well-liked because it gives you a clean, compact DAC with genuinely useful power, balanced and single-ended headphone outs, and flexible USB/optical/coax inputs. If it’s complete and working properly, this is the kind of piece that’s easy to recommend as a sensible step-up for a desktop setup; at this price, the main thing to confirm is that the power supply and all included bits are present.

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.
