Against the obvious alternative of the standard K11, £110 is a fair price rather than a bargain. Your comparable listings put the median at £99, with the middle 50% running from £91 to £112, so this sits comfortably within the normal used market—slightly above median, but not ambitious.
The R2R version earns that position with a more distinctive, generally organic presentation, while retaining the K11’s useful desktop flexibility: USB, optical and coaxial inputs, RCA line-out, selectable NOS/OS modes, and a powerful 4.4mm balanced output. It is a particularly capable one-box DAC/headphone amp for the money, with enough output for demanding headphones and sensible gain options. With unknown condition, check the screen, volume control, both headphone sockets and included power supply; if clean and complete, £110 is an easy recommendation.

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.
