Integrated amplifier L-509Z

The history of the LUXMAN audio brand began in 1925, at the birth of radio broadcasting. LUXMAN has paid particular attention to the world of audio and has gained high reputation as a quality brand of high-end audio products both domestically and internationally.
People tend to open their mind to natural things and react negatively to the unnatural. Natural sound, without coloration, develops an intimacy between the music and the listener.
Naturally and purely reproduced music resonates with the listener’s imagination. LUXMAN reflects this effect in our product development. Music that features a performer's true passion and which a recording engineer has worked on precisely benefits from the fine nuances in sound which LUXMAN aims to reproduce, conveying the sprit of the artist and the enthusiasm of the performance. We strive to bring to the listener the experience of unlimited, pure music.
Composers, performers and recording engineers have poured their true feelings into our favorite pieces of music. LUXMAN would be satisfied if the listener could experience those same passions through our products. LUXMAN has celebrated its 90th anniversary and hopes to discover new excitement through wonderful music and to continue to share that pleasure with everyone.

Taking our Z-Series integrated amplifiers to a performance peak

Here are important developments that Luxman Engineers adopt for this model - derived from our M-10X amplifier; 

Electronically controlled attenuator LECUA-EX* incorporating an elaborate rotation mechanism

A tactile, satisfying volume control function is essential for audio amplifiers. To feed a fixed gain power amplifier with a musical signal at a level suitable for listening, precise control is required to smoothly attenuate the voltage while maintaining the quality of the input source. LECUA, developed by LUXMAN, is an electronically controlled attenuator system that switches through a series of high-quality, fixed value resistors for each channel independently. It results in accurate left/right balance, low noise and low distortion.

Our latest amplification feedback engine literally brings music to life with LIFES* Version 1.0

By feeding back only the distorted components generated in the audio signal’s journey to the final amp stage, LUXMAN’s proprietary “ODNF” amplification circuitry achieves excellent static characteristics and natural sound quality as if it were a “non-feedback” system. This is important, as most amplifiers use too much feedback, and this can lead to a lifeless sound. With the Luxman the energy and snap of a performance remains intact.

The output section utilizes three stage Darlington bipolar transistors in quadruple-paralleled push-pull configuration to achieve outstanding output power and near perfect power linearity performance comparable to a standalone power amplifier, developing 120W+120W at 8 ohms and 220W+220W at 4 ohms.The result is spectacular sound quality with an abundance of energy.

*ODNF stands for “Only Distortion Negative Feedback”
*LIFES stands for “Luxman Integrated Feedback Engine System”.

Generous power supplies

The power supply section requires instantaneous current supply and high voltage stability. The L-509Z is equipped with Luxman's traditional high-inertia power supply circuit with a 600VA EI-type custom transformer that boasts high regulation and newly developed large-capacity block capacitors (10,000μF x 8).

In terms of frequency response, the Luxman L-509Z is truly exemplary. For Phono input, it manages a frequency range from 20Hz to 20kHz with a precise deviation of ±0.5dB, fantastic for vinyl aficionados.


"Recordings were presented in near-3D on a generous stage with munificent images. In those respects, the Luxman outperformed other integrated or separate amplifiers I've reviewed or had/have in house"
"The Japanese company's flagship integrated merits a "Sai-kōkyu" designation. We call it Class A."
