At US$70, this Fiio E9 desktop headphone amplifier is a genuine bargain, sitting well below the 25th percentile of US$60 in the recent comparable used market data, where the median is US$101 and the 75th percentile is US$175. This asking price is significantly lower than the original retail of US$129, marking it as a strong deal for a fellow enthusiast seeking entry into quality desktop amplification without overspending.
The E9 is well-regarded for its robust engineering, delivering 1W into 16Ω to power demanding headphones like the HD650 effectively, while offering low distortion under 0.003% and versatile connectivity including USB, line-in, and RCA outputs. Its compact footprint and protection relay make it a reliable, high-value addition to any desktop setup, and at this price, it represents a clear buying opportunity rather than a risky purchase, especially if the unit includes original accessories or retains original-owner condition.

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.
