Angeboten wird „Aqua III 274B Blue tube“ von Sophia Electric aus der Kategorie „Audio-Röhren“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 4150111296 endet am 29.07.2026 um 16:12 Uhr.
Sophia Electric’s 274B Blue is a well-regarded specialty tube, and at €190 this looks like a strong bargain versus your recent EUR comps: it sits far below the €886 25th percentile and way under the €1,577 median. On your own market data, this is priced like a clear opportunity rather than a merely fair buy.
The upside here is straightforward: if the tube tests healthy, you’re buying into a respected boutique valve with real audiophile appeal at a very low entry point. A good-condition listing is especially attractive on a part like this, where provenance and light use matter more than cosmetic perfection; just make sure it’s the exact variant you need and that there’s no hint of excessive wear, mismatch, or testing uncertainty.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sophia Electric traces its origins to two small custom amplifier makers on the U.S. East Coast, evolving into a dedicated hi-fi brand in 2001 when Richard Wugang, a former banker, audiophile, and collector of vintage classic amplifiers, infused capital, marketing savvy, and industrial expertise. Based in Washington, DC, the company recruited top U.S. designers and engineers, drawing deep inspiration from historic designs by Western Electric, RCA, Klangfilm/Siemens, and UTC. This research-oriented approach laid the foundation for innovative products that honor tube amplification's golden era.
The brand specializes in high-end vacuum tubes, particularly renowned for recreations like the Classic II 300B—infused with the "vintage WE 300B soul"—alongside Blue Glass series in 300B, KT66, KT88, EL34-ST, 6SN7, and 274B variants. It also produces tube amplifiers, speakers, and audiophile-grade capacitors, emphasizing single-ended triode (SET) designs prized for their midrange magic, rich tonality, and expansive soundstages.
Positioned as a niche boutique leader in the U.S. audiophile market, Sophia Electric commands respect among tube enthusiasts for superior sound quality that rivals or surpasses vintage benchmarks, though some note physical fragility in production. With a growing international footprint in Europe and Asia, it appeals to discerning buyers seeking innovative, soulful high-end components over mass-market reliability.
