Sonic Frontiers Line 2 Pre Amplifier Sonic frontiers line 2 balanced pre amplifier . Has new golden lion 6922 valves fitted . High quality tube pre in good working order https://www.stereophile.com/tubepreamps/769/index.html Condition: Excellent Payment Method: Cash EFT Region/State: (VIC) Victoria/Australia By Alex_4man 3 Comments AUD $2,000 Date: December 15, 20241 yr
A $2,000 ask is clearly above the A$733 median and well into the upper half of the market, though still below the A$3,203 75th percentile, so it reads as ambitious but not outrageous rather than a bargain. Against that spread, it is best judged as a premium listing that needs the condition and provenance to do the heavy lifting.
That makes sense if this is a clean, well-kept example: these preamps are respected for a big, open, slightly romantic presentation with strong drive and scale, and they’ve got a following among tube-gear listeners who want real meat on the bones without losing refinement. Excellent condition is a genuine plus here, and if it’s complete with remote, packaging, and a healthy service history, the ask is easier to justify; if anything is missing, the price starts to feel less compelling.
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.
