Ich verkaufe hier meinen Fosi Audio T20 Röhrenverstärker, der sich ideal für Bastler oder Tüftler eignet.
- Modell: Fosi Audio T20
- Bauart: Röhrenverstärker
- Kompaktes schwarzes Gehäuse

Aktuell liegt ein Defekt vor, da nur einer der beiden Ausgangskanäle ein Signal wiedergibt. Mit etwas technischem Verständnis lässt sich das Problem sicher schnell beheben. Das Gerät ist ansonsten in einem optisch gepflegten Zustand.
Ich freue mich auf deine Nachricht, falls du Interesse an diesem Projekt hast.
The T20 sits in Fosi’s entry-level tube-tinged amp camp, and at €50 this looks like a solid buy against the local used market: below the €61 median and safely under the €104 75th percentile, so it’s priced on the attractive side rather than the risky side. It’s not a bargain-basement steal at €42 or less, but it is clearly fair for a niche little integrated amp.
What makes it worth a look is the appeal of a compact, inexpensive hybrid-style amp that can add a touch of warmth and drive to a small desktop or secondary system without much cash outlay. The big caveat is the listed defect: for parts means you should only buy if you want to repair it, harvest tubes/components, or you already know the fault is minor and fixable. If you were hoping for a plug-and-play amp, pass.
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.
