Taking our Z-Series integrated amplifiers to a performance peak.

Introducing our next-level “single-chassis separates” concept,pursuing the ideal with a new, all-in-one flagship amplifier.Taking our Z-Series integrated amplifiers to a performance peak. As the premium model for the new Z-Series generation, the L-509Z has evolved beyond the concept of a traditional integrated amplifier. Both the preamplifier and power amplifier sections simultaneously use our new generation amplification feedback engine “LIFES” for the first time. The volume control is supported by our new “LECUA-EX” 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.

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. 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 realize “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 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.

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. These are neatly arranged on the sub-assembly according to the position of the volume control knob. Since the release of the C-1000f control amplifier in 2006 to commemorate LUXMAN’s 80th anniversary, “LECUA1000”, which similarly integrates into the amplification circuitry, has been used in many LUXMAN products as a volume control system that minimizes the effects of external vibrations and changes in sound quality across the operating range of the volume control and is also resistant to deterioration over time. The L-509Z combines a highly precise rotary encoder with a newly developed weighted rotation mechanism to create the “LECUA-EX”, which offers even greater reliability and a natural, high-quality operational feel. 88 fine steps from 0 to 87dB and an acceleration setting for the speed at which the volume knob is rotated and a long-press setting for the remote control allow for comfortable and thorough volume control action with minimal degradation in sound quality.
