Offered is „FBA-800“ by Sugden as second-hand device from the category „Transistor-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 4724302843 ends on 21.12.2026 at 16:22 o'clock.
€4,650 looks fair to good, sitting close to the observed used-market level rather than being an obvious bargain. A comparable used example has been advertised at €3,900, while another is listed at €4,650, so this price is defensible if the condition really is good and the listing is complete.
The FBA-800 is a serious pure-Class-A design: 40W into 8 ohms, with unusually strong control, low noise, and the lucid, tonally rich presentation for which Sugden is admired. Its floating-bridge topology gives it more authority than the modest power rating suggests, making it especially attractive with revealing, reasonably efficient speakers. Confirm that both RCA and XLR inputs work, allow plenty of ventilation—the amplifier runs hot—and check for original packaging and a clean service history. At €4,650, those details determine whether it is merely fair or genuinely worthwhile.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sugden Audio: British Heritage and Class A Excellence
Sugden Audio was founded in 1967 by James Edward Sugden in Cleckheaton, West Yorkshire, as a division of Research Electronics, his earlier scientific instrument manufacturing company. Sugden's background in precision engineering and broadcast equipment design at EMI informed the company's founding philosophy of meticulous craftsmanship and sonic integrity. The brand has remained rooted in British manufacturing throughout its history, maintaining its West Yorkshire base and family involvement through successive generations, most recently under the stewardship of the Miller family alongside the long-term Sugden team.
The company is synonymous with Class A solid-state amplification, having pioneered this technology with the legendary A21 integrated amplifier in 1967—widely recognized as the first commercially produced pure Class A solid-state amplifier. Sugden's product portfolio centers on high-end electronics, particularly integrated and power amplifiers, alongside preamplifiers. The brand's design philosophy emphasizes minimalism and musicality over unnecessary features, captured in their tagline "Rescuing Music from technology." All products are hand-built to exacting standards, reflecting Sugden's commitment to quality over mass-market appeal.
Sugden occupies a distinctive position in high-end audio as a niche boutique manufacturer with deep credibility among serious audiophiles and collectors. The A21 remains in continuous production—now in its A21a iteration—making it one of the longest-running models in specialist hi-fi. Vintage Sugden equipment has become highly sought-after by collectors, while contemporary designs maintain the brand's reputation for sonic excellence and engineering precision that has defined British audio craftsmanship for nearly six decades.
