Compared with buying it new, €65 lands right on the current used-market median and looks like a fair, sensible ask rather than a bargain or an overreach. With the 25th percentile at €54 and the 75th at €75, this sits squarely in the normal range, so the value case depends more on condition and completeness than on a dramatic price edge.
That makes it a worthwhile buy if it’s clean, fully working, and includes the useful bits you’d want in hand. The SK01 has a good reputation as a compact, practical desktop headphone amp/DAC-style piece that punches above its size for casual listening and headphone setups, so a tidy example at this price is easy to like. If it’s original-owner and unmodified, that’s a nice plus; if anything is missing, the price should be nudged down a touch rather than treated as special.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Fosi Audio emerged in January 2017 from a modest 10-square-meter office in Shenzhen, China, founded by Ryan Huang and a partner driven by the conviction that high-fidelity sound should be accessible without elite pricing. The brand represents the new wave of Chinese audio manufacturers challenging the traditionally expensive import-dominated hi-fi market. In less than a decade, the company has grown from a confidential startup to an internationally recognized player, now operating from an R&D center spanning over 2,300 square meters and holding more than 100 patents.
Fosi Audio's product portfolio spans the full spectrum of hi-fi components, with particular strength in compact amplifiers and digital-to-analog converters that deliver disproportionate performance for their price point. The brand manufactures integrated and multi-channel amplifiers, DACs, headphone amplifiers, preamplifiers including phono stages, passive subwoofer modules, speakers, headphones, and cables. This comprehensive range reflects a deliberate strategy to serve both entry-level enthusiasts and experienced audiophiles seeking value-oriented solutions rather than feature-laden complexity.
The brand occupies a distinctly mid-tier, value-conscious position in the market, distributed across more than 150 countries and frequently ranking atop Amazon's hi-fi charts. Fosi's reputation rests on pragmatic engineering—delivering compelling sound quality through efficient, optimized electronics rather than pursuing systematic upscaling. The company sells directly through its website, Amazon, and AliExpress, backing products with lifetime technical support and a 24-month warranty, positioning itself as an accessible gateway into serious hi-fi rather than a luxury or boutique concern.
