At US$1,795, this lands right on the median of the recent used-market comp set, so it reads as a fair, normal ask rather than a bargain or an overreach. The price is squarely in line with what these heavy-duty KT88 mono amps have been changing hands for, and it’s not priced low enough to scream quick-sale opportunity.
What makes it appealing is the usual tube-mono appeal: serious current delivery, big dynamics, and the kind of dimensional, fleshed-out presentation KT88 push-pull amps are loved for. If the pair is clean, quiet, and comes with healthy tubes and any original packing or manuals, that’s the upside here; at this price, the main thing to verify is tube life, matching, and whether both amps are operating evenly.
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.
