Compared with a typical used desktop amp buy in the US$400-ish range, this is an outright bargain at US$60. Against a recent used median of US$414 and even the low quartile at US$368, the asking price sits so far below market that it reads as a strong deal rather than a negotiation starting point.
The E9 is well-liked as a simple, powerful desktop headphone amp: plenty of clean output for hard-to-drive headphones, a straightforward no-drama design, and a reputation for doing its job without fuss. At this price, the main appeal is value, especially if it powers up cleanly and includes the right power supply and interconnects; on a budget like this, even a cosmetically tired unit can still be a smart grab if it’s functional.

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.
