#### in prijs verlaagd #### te koop aangeboden: een unieke en complete set bestaande uit twee fosi audio v3 mono blok eindversterkers, twee krachtige optionele 48v/10a gan voedingen en twee hoogwaardi
This is a seller’s market at €350 for a V3 Mono. Against your recent EUR comps, that sits well above the 75th percentile of €231 and far above the €170 median, so it reads as ambitious rather than fair.
The upside is that the V3 Mono is a genuinely well-liked little class-D monoblock: clean, punchy, very low-noise, and a strong choice for compact systems or a tidy stereo pair with separate channels. If the listing includes the right power supply and is in truly excellent condition, that helps, but at this price I’d want original accessories and a clear reason for the premium; otherwise, there are better-value buys in the usual used range.
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.
