Our Thoughts RADAR AI

Is £79 a fair buy for this amp, or are you paying a touch over the going used rate? Against your recent UK comps, it lands a bit above the £68 median and just over the £78 75th percentile, so this reads as slightly ambitious, not outrageous.

That said, the V3 is well-liked because it delivers a lot of clean power for the money, with a compact footprint and the kind of straightforward no-fuss performance that suits desktop or secondary systems. If it’s genuinely tidy, working properly, and comes with the right PSU and any original bits, it’s still a sensible pick for someone who wants a compact Class D amp without shopping the bargain-bin end of the market.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Fosi Audio

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.
