Angeboten wird „OTL Headphone Amplifier Basic Line“ von EternalArts als Gebrauchtgerät aus der Kategorie „Kopfhörerverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 6870383555 endet am 22.07.2026 um 17:59 Uhr.
At €780, this sits well below the €955 median and even under the €1,000 mark for a recent used listing set, so it reads as a solid buy rather than a stretch. It is not quite a steal on the numbers alone, but it’s clearly better than fair-market and close enough to the lower half of the pack to feel attractive for an OTL headphone amp in good condition.
The appeal here is the usual OTL payoff: a big, easy, harmonic presentation that often suits high-impedance dynamics especially well, with more density and flow than many solid-state alternatives. If the unit is clean, quiet, and complete, the main upside is simply getting into a well-liked tube headphone amp without paying top-of-market money. I’d still confirm tube health, hum/noise, and whether any original accessories are included, but this is the kind of listing that looks worth chasing.
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.
