Mr. Zheng Cai and Mr. Zheng Xi founded Line Magnetic Audio‑Foshan Studio in Foshan, devoting themselves to the restoration and replication of vintage high‑end audio equipment. Dedicated to researching traditional audio craftsmanship, they refined core technologies including point‑to‑point hand‑wiring and the design & manufacturing of audio transformers. By accumulating extensive hands‑on experience and process data, they laid a solid and profound technical foundation for the R&D and iteration of Line Magnetic’s full range of subsequent tube audio products.

Zhuhai Line Magnetic Audio Co., Ltd. settled in Nanping Science & Technology Industrial Park of Zhuhai. It officially kicked off the R&D of commercial tube power amplifiers, established standardized production systems and achieved large‑scale mass production of complete units. Drawing on core craftsmanship accumulated at the studio, including point‑to‑point hand‑wiring and audio transformer technologies, the company organically integrates traditional tube‑amplifier craftsmanship with modern production management. Balancing artisanal heritage and industrial manufacturing strength, it commercializes Line Magnetic tube audio products and delivers high‑quality finished units to global users.

Line Magnetic successively launched classic integrated tube amplifiers of Series 2, including the LM‑216IA and LM‑219IA. Adhering to point‑to‑point hand‑wiring craftsmanship and equipped with self‑developed audio transformers, it maintains stringent standards for circuit tuning, component matching and complete‑unit assembly. The brand actively took part in major Hi‑Fi audio shows, leveraging offline exhibition platforms to demonstrate product performance and craftsmanship philosophy, and conducting in‑depth exchanges with audiophiles. As a result, the Line Magnetic brand gradually built up its reputation within the audiophile community and achieved high‑level industry visibility and market recognition.

We aim to bring an exceptional music‑listening experience to more audiophiles worldwide. We will continue expanding into overseas markets including Europe and Southeast Asia, and gradually improve our localized dealer service network. This opens up experience and purchasing channels for Hi‑Fi enthusiasts in different regions, allowing overseas users to access and appreciate the charm of our products with greater convenience.

Building upon years of accumulated R&D achievements, we accelerated technology commercialization and product iteration. Our product lineup expanded from core tube amplifiers to diverse Hi Fi categories including CD players, DACs and field coil loudspeakers. We built a complete product tier portfolio spanning entry level models all the way to high end flagships.

Our R&D and innovation capabilities have received official national accreditation. Taking this milestone as a new starting point, we continue to deepen our expertise in tube‑amplifier development. We increase investment in core‑technology R&D to drive innovation and upgrades in circuit architecture, material craftsmanship and acoustic solutions, laying a solid technical foundation for subsequent product iterations and global‑market expansion.

The company completed full relocation to a brand new modern purpose factory site. Our R&D center, standardized assembly workshops and professional Hi Fi listening showrooms have been comprehensively upgraded. Comprehensive improvements have been made to manufacturing, R&D and customer experience infrastructure, marking a new development phase for production capacity expansion, new product innovation and global business growth.

Driven by technological innovation, we completed multiple rounds of product iteration and rolled out a series of key new models to the market. Advancing with dual‑track strategies for domestic and international business, we continue to empower global channel partners via well‑established localized dealer‑service networks. Our products reach more Hi‑Fi enthusiasts at home and abroad, further expanding the brand’s global influence.
