Overview

Line Magnetic is a Chinese manufacturer of high-end audio equipment specializing in tube amplifiers that replicate 1950s American designs from brands like Western Electric and Altec Lansing. The company combines classic tube technology with modern engineering to produce products known for their point-to-point wiring and focus on warm, transparent sound reproduction. It has expanded to two factories and received awards such as the China Good Design Award.

History

Line Magnetic Audio Co., Ltd. was founded in 2005 in Zhuhai, China, by the Zheng brothers, who specialized in repairing and replicating legendary HiFi products due to the rarity of tubes in China. They leveraged this expertise to develop their own tube amplifiers. The company has grown to operate two factories while maintaining hand-wired point-to-point connections as a core design principle.
