Luxman has represented the excellence of Japanese hi-fi since 1925, the year it was founded in Japan by T. Hayakawa and K. Yoshikawa. Originally headquartered in Osaka, Luxman Corporation is one of the world's oldest audio manufacturers, positioning itself in the premium high-fidelity segment with the motto "Ultimate Fidelity since 1925." The Japanese brand is internationally recognized for its rigorously Made in Japan construction quality and for its proprietary technologies that have revolutionized the global hi-fi landscape.
The history of Luxman begins in June 1925, when the company was born as the radio department of the Kinsuido Picture Frame Store in Osaka, the very year that radio transmissions began.missionin Japan. Initially focused on importing American and European radio equipment, Luxman soon developed the philosophy of producing components in-house to ensure greater quality and cost control. This forward-thinking vision led to the creation of the Luxman brand and the specialization in the production of high-quality output transformers, which became the company's flagship. The company's philosophy is based on a fundamental principle: to offer a natural tonal balance that does not alter the original musical message, allowing audiophiles to get as close as possible to the artistic vision of musicians and recording engineers. Luxman pursues the pursuit of "naturally reproduced music" through a sound free of coloration, capable of creating intimacy between the music and the listener.
Luxman's distinctive technologies represent the innovative heart of the Japanese brand. The ODNF (Only Distortion Negative Feedback) circuit in its latest version 4.0 represents a revolution in amplification, applying negative feedback exclusively to the distorting components of the audio signal. This technical solution guarantees faster initial response, ultra-wide bandwidth, and extremely low distortion levels, especially in the high frequencies. The LECUA (Luxman Electronically Controlled Ultimate Attenuator) system represents another proprietary innovation: it is a high-precision computerized attenuator with graduated fixed resistors, available in the LECUA1000 version with 88 adjustment steps that minimizes deterioration in sound quality even at the lowest volumes. The new LIFES (Luxman Integrated Feedback Engine System) version 1.0 technology, introduced in the Z series, has simplified and optimized the entire circuit by reducing the number of elements in parallel and halving distortion during amplification. The LxDTM (Luxman Digital Transport Mechanism) system for digital players ensures rigidity and precision in signal processing.
The Luxman product range covers the entire hi-fi chain with solutions for every audiophile need. The integrated amplifier category includes legendary models such as the L-509Z, the top of the range Z series with LIFES technology and LECUA-EX attenuator, and the L-505uXII with ODNF 4.0 circuitry, representing ideal solutions for those seeking reference-level transistor integrated amplifiers. For tube lovers, Luxman offers integrated amplifiers such as the LX-380 with 6L6GC tubes, perfect for those seeking a warm and musical tube integrated amplifier. The power amplifier section boasts models such as the M-10X, described as "the ultimate amplifier" to celebrate the company's centenary, ideal for those seeking power amplifiers of absolute excellence. Pre- and power amplifier combinations such as the C-900u and M-900u offer the ultimate in pre-amps for reference-level stereo systems.
Luxman's product series are distinguished by specific technical features and audiophile-grade appeal. The L Series represents the heart of the lineup, featuring Class A/B integrated amplifiers such as the 110W-per-channel L-509Z and the L-507Z with LIFES 1.0 technology. The pure Class A Series includes iconic models such as the 30W-per-channel L-595A Special Edition, which faithfully replicates the aesthetics and sound quality of the legendary L-570 series after 30 years. The Z Series represents the next generation with LIFES technology, representing the most advanced evolution of Luxman design. The digital player range includes the D-07X for top-of-the-line CD, SACD, and DVD players with MQA decoding and dual Burr Brown converters, the D-03X with support for Hi-Res PCM files up to 384kHz/32bit and DSD 11.28MHz, and the D-N150 from the NeoClassico II range, which blends audiophile design and digital flexibility. Turntables such as the PD-191A with a brushless DC motor and belt-drive system complete the premium turntable offering. For those looking for complete sources, Luxman offers integrated solutions for every type of music source.
