Luxman

Japan's oldest premium audio house, since 1925

History

Luxman Corporation traces its origins to 1925 when it was established as the Kinsuido Picture Frame Store in Osaka, Japan. The company's founder, a radio enthusiast, began selling radio parts from a counter in the back of the shop. By 1936, the business had transitioned to Lux Corporation, manufacturing radio chassis and transformers. The Luxman brand officially emerged in the post-war period, quickly establishing itself as a premium Japanese audio manufacturer. The company's focus on high-quality transformers, superior chassis construction, and elegant design set it apart from mass-market competitors. In 1981, Luxman released the L-550—the world's first pure Class A integrated amplifier. This groundbreaking product delivered 50 watts per channel of Class A power, establishing Luxman's reputation for no-compromise amplification. The L-550 series continued through multiple iterations (L-550, L-550X, L-550Z, L-570, L-580) over three decades. The company formed a business partnership with Alpine in 1984, and later with Azden in 1994. Today, Luxman operates as a specialized high-end audio manufacturer, continuing to produce amplifiers, CD players, and turntables of exceptional quality.
