As the premium model for the new Z-Series generation, the Luxman L-509Z has evolved beyond the concept of a traditional integrated amplifier. Both the preamplifier and power amplifier sections simultaneously uses Luxman's new generation amplification feedback engine “LIFES” for the first time. (Luxman Integrated Feedback Engine System)

The volume control is supported by Luxman's new LECUA-EX (Electronically Controlled Ultimate Attenuator - Excellent eXperience) attenuator system that suppresses sound quality deterioration and realizes a more precise feel of operation. The “single-chassis separates” concept, which aims for the ultimate in integrated amplifiers, now achieves unprecedented performance.

Pursuing the ideals of audio enthusiasm, we are combining our passion for music with improved technology. The L-509Z, a new pinacle of Luxman integrated amplifier design.

LIFES Version 1.0 - Brings Music to Life

During the development of the M-10X flagship stereo power amplifier launched in 2021, technical concepts explored there were retained and the circuit configuration, which had become very complex over years of improvements has been completely redesigned to realise “LIFES” exquisite, high-fidelity sound and defines an amplification feedback engine blueprint for our next generation of components.

The L-509Z is equipped with independent LIFES modules operating simultaneously in each of its fully discrete pre and power sections. The L-509Z is a pre-main amplifier that is worthy of the “single-chassis separates” concept that incorporates quality seperate units into a single, elegant chassis and has achieved an elevated level of musicality and unprecedented detail in comparison to other amplification circuits.

The output section utilises 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.
