The Luxman L-507Z integrated amplifier is the debut model heralding Luxman's new generation of amplifier products. Featuring their newly developed LIFES amplification feedback engine, we look towards the future of Luxman.
This amplifier has realised a dramatic development in musicality that goes far beyond its class. The Luman L-507Z combines advanced technology and sophisticated functionality.
LIFES Version 1.0 - Brings Music to Life
Luxman celebrates its 100th anniversary in 2025 and they are proud to announce the successor to the ODNF (Only Distortion Negative Feedback) feedback circuitry, which has contributed to the audio quality of Luxman amplifier products since 1999.
Luxman have developed a new amplifier feedback circuit called LIFES, (Luxman Integrated Feedback Engine System) which has acquired realistic, fresh and rich musicality and overwhelming audio performance. LIFES is based on the technical concept of the ODNF circuit and realises excellent, dynamic characteristics without feeding back any of the original audio input signal to the main amplifier.
This achieves a remarkably natural sound quality, almost if it were a non-feedback equipped circuit. The design has been conceived and expanded upon from first principles using simulation technology and painstaking research.
By repeatedly auditioning, rigorously scrutinising and combining specially selected components, they have achieved supreme performance characteristics and a level of quality suitable for use in Luxman’s next-generation products.
In producing LIFES Version 1.0, by carefully reimagining the entire circuit, Luxman succeeded in reducing the number of paralleled elements while improving performance. The distortion in the amplification stage has been reduced to less than half of their previous system.
The output stage features a 3-stage Darlington triple-paralleled push-pull configuration and achieves a class AB power output of 110W+110W (8Ω) and 210W+210W (4Ω). The high output power, comparable to that of a separate power amplifier, effortlessly realises a natural soundstage, full of energy, to confidently drive any compatible speaker system, and bring out the best of its characteristics.

Large Needle VU Level Meter and 7-Segment LED
Needle-type analog VU meters are a symbolic design statement of Luxman’s solid state integrated amplifiers. The L-507Z is equipped with a large dual meter with bright LED back-lighting and high response characteristics.
Luxman have adopted such a display so the movement of the needles synchronises with the dynamics of your music. In addition, newly included 7-segment LEDs display the attenuation level in between the left and right level meters so that the current attenuation amount can be easily seen from the listening position.
The level meter back-lighting and LED display can be turned on and off using the remote control.
Precision Hairline Finished Aluminium Top Panel
The rectangular chassis housing design features an ultra-thick front panel with a high-quality, blasted white finish. This has become a brand identifier of current Luxman products, with a delicate hairline finished aluminium top panel, a luxurious exterior design adopted for their high-grade amplifiers.
The large ventilation slots on the top panel provide sufficient air flow and the entire chassis housing is fabricated from aluminium panels, providing excellent heat dissipation, ensuring the stable operation of this product.
