US$400 is above the median US$183 and well above the 75th percentile at US$896? No — it actually sits comfortably below the 75th percentile and reads as a fair ask for this niche passive Line Magnetic piece. It is not a bargain-bin score, but it is also not an aggressive ask for a specialized attenuator/preamp that tends to appeal to a narrower buyer pool.
That makes it interesting if the unit is clean and complete, because passive line stages can be wonderfully transparent, simple, and low-maintenance when they match the rest of the system. The upside here is strong if it comes from a careful owner with original packaging, a solid provenance, and no channel-tracking issues or worn switch contacts, since those details matter more than cosmetic fuss on this type of component.
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.
