At US$170, this is a strong deal: it sits well below the US$236 median and comfortably above the US$85 lower quartile, making it a particularly attractive buy if the unit is fully functional. It is nowhere near an ambitious price against the six recent sold comparables.
The QX13 is a serious portable DAC/amp rather than a basic dongle, with a 4.4mm balanced output, useful 3.5mm connection, color display, parametric EQ, and enough balanced power for demanding headphones. Desktop mode reaches 900mW per channel into 32 ohms, while USB decoding extends to PCM 768kHz/32-bit and native DSD512. With condition listed as unknown, confirm that the display, USB ports, both outputs, battery or external-power operation, and included case/cables are present—but at this price, it remains a compelling opportunity.

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.
