Sophia Electric 845 Monoblock Power Amplifier I purchased these Amplifiers directly from Sophia Electric in 2011. These are designated Sophia Princess 206 Drive, 845 Monoblock Amplifiers. These Amplifiers are also designated as old model amps. The Serial numbers are 2001 and 2002. With the exception of the Sophia 845 tube iteself, all tubes are orignal as supplied from Sophia. Me personally, Sophia 845 tubes have not been kind to me. I have run various NOS tubes with these amps and have had much better success. Shortly after purchasing these amps, I purchased a pair of DeHavilland 845's

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.
