kr900 is fairly priced, slightly on the friendly side versus the recent used market, sitting above the kr764 25th percentile but below the kr936 median. It is not a bargain-bin price, but it is close enough to the middle of the pack that a clean unit should be easy to justify.
That makes it a sensible buy if the condition is genuinely good and the seller can confirm normal operation. The P4 is well liked for giving a straightforward, transparent preamp experience without fuss, so the real upside here is getting a capable piece of kit at a sensible used price. With condition listed as unknown, I’d mainly want clarity on cosmetic state, knob/switch operation, and whether the original power supply and accessories are included; if those check out, this looks like a solid pick.
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.
