It's a buyer's market for used Line Magnetic gear right now, with solid S-15 examples turning up regularly. At EUR 90 in excellent condition, this is a screaming bargain—well below the median of EUR 344 from recent comparable EUR listings (25th percentile EUR 91, 75th EUR 1,199). Snag it if the rest checks out; these SET amps deliver that addictive single-ended magic without breaking the bank.
Before committing, verify the output tubes (common wear point on these Chinese builds—expect to swap EL84s soonish) and confirm all original accessories like the wood chassis, power cord, and manual are included. Probe the seller on usage hours and any hum or microphonics, as early units could date back 5-10 years. Test for channel balance if possible.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Line Magnetic Audio: Brand Overview
Line Magnetic Audio was established in 2005 in Zhuhai, China, by brothers Zheng Cai and Zheng Xi, both passionate audiophiles with deep roots in tube electronics. Zheng Cai's background as a former general manager and chief engineer at Cayin, combined with years spent studying and restoring classic Western Electric, Altec, and Jensen components, provided the technical foundation for the company. This heritage of reverse-engineering and understanding legendary 1950s American audio design remains central to Line Magnetic's identity and philosophy.
The brand specializes in tube-based electronics and speakers, with a product range spanning integrated amplifiers, preamplifiers, power amplifiers, DACs, phonostages, and horn-loaded loudspeakers. Line Magnetic is particularly renowned for its meticulous replicas of classic Western Electric, Altec, and Jensen designs, as well as proprietary field-coil drivers that have earned respect among both manufacturers and DIY enthusiasts. All products are hand-assembled using point-to-point wiring across two factories, reflecting an uncompromising manufacturing philosophy.
Line Magnetic occupies the high-end boutique segment, targeting discerning collectors and audiophiles who value vintage-inspired design married with modern engineering. The brand commands respect for its scholarly approach to audio history, rigorous material research, and unrelenting build quality. Rather than pursuing mass-market appeal, Line Magnetic has cultivated a devoted global following among those seeking authentic tube sound and meticulous craftsmanship.
