Luxman L-507Z Class A/B integrated amplifier

L-507Z – Class A/B integrated amplifier

The L-507Z inaugurates the new generation of the Luxman Z series. As the first integrated amplifier with the new LIFES amplifier feedback engine, it redefines musicality and sonic fidelity. With its combination of advanced technology, high output power, and precise signal processing, it exceeds expectations for its class, delivering an energetic, natural listening experience of the highest caliber.

Elegant case design and analog display

The signature analog needle level meters are equipped with LED backlighting, making the dynamics of the music visible. Newly added 7-segment LEDs display the volume, which is easily readable from the listening position. The ultra-thick, sandblasted aluminum front panel and the delicate aluminum top give the L-507Z a luxurious appearance. Large ventilation slots ensure optimal heat dissipation.

LIFES – Luxman Integrated Feedback Engine System

At the heart of the L-507Z is LIFES technology, based on the ODNF circuit. Distortion is selectively fed back without compromising the original signal quality, resulting in exceptionally natural sound reproduction. The three-stage Darlington parallel push-pull output stage delivers 110 W at 8 ohms or 210 W at 4 ohms – enough power to drive any loudspeaker system with ease.

Innovative sound technologies

The integrated LECUA1000 attenuation control provides lossless volume control across 88 steps. The Beeline design, angle-free circuit board routing, and loop-free chassis structure ensure interference-free signal transmission. Two headphone outputs (6.3 mm and 4.4 mm) with independent ground connections guarantee excellent LR isolation for an immersive, three-dimensional soundstage.

Robust power supply and high-quality components

A highly regulated EI power transformer, combined with large-capacity filter capacitors, ensures a stable power supply even during dynamic passages. Large, low-impedance speaker relays and proprietary OFC cables transmit the output power without loss. Cast iron feet minimize vibrations and protect the precision of the audio reproduction.
