Unknown condition at £47 makes this look like a very strong buy versus the recent UK used market: it sits well below the £272 25th percentile and far under the £306 median, so the asking price is bargain territory. For a portable DAC/headphone amp/preamp, that leaves plenty of room for a tired battery, cosmetic wear, or simply missing extras and still land comfortably under fair market value.
The E17 is well-liked because it’s a compact all-in-one that can clean up a laptop or phone source, drive easy-to-moderate headphones, and double as a handy preamp in a small desktop setup. The main thing to check is practicality rather than pedigree: battery health, charger/cable inclusion, and whether the outputs, buttons, and display behave properly. If it’s complete and working, this is the kind of listing that feels more like an opportunity than a gamble.

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.
