Luxman L-509Z — The Definitive Integrated Amplifier
The definitive integrated amplifier. 120 watts of Japanese perfection.
The L-509Z is Luxman's flagship integrated amplifier — the culmination of nearly a century of Japanese audio engineering distilled into a single, uncompromising chassis. With ODNF 5.0 amplification, LECUA-EX volume control, and 120W per channel of pure Class-AB power, it doesn't just compete with the best separates — it renders them unnecessary.

What makes it exceptional
ODNF 5.0 Amplification
Luxman's fifth-generation Only Distortion Negative Feedback circuit achieves vanishingly low distortion (0.003%) by targeting only the distortion component for correction — leaving the original musical signal untouched. The result is effortless dynamics and breathtaking transparency.
LECUA-EX Volume Control
The latest evolution of Luxman's legendary Electronically Controlled Ultimate Attenuator uses 88 precision resistors per channel, switched via gold-contact relays. Perfect channel balance at every volume level — from midnight listening to full-scale orchestral peaks.
120W × 2 Class-AB Power
Massive toroidal transformer and high-capacity power supply deliver 120 watts per channel into 8 ohms (doubling to 240W into 4 ohms), with peak current capability that effortlessly controls even the most demanding loudspeakers.
Dual Mono Construction
Left and right channels are completely separated from power supply through amplification stages, minimising crosstalk and ensuring an enormous, holographic soundstage with pinpoint imaging.
In-House Transformer Manufacturing
The custom-wound toroidal power transformer is designed and manufactured at Luxman's Yokohama factory — the heart of the amplifier's effortless power delivery and dead-silent noise floor.
Copper-Plated Chassis
Internal copper plating provides superior electromagnetic shielding, while the machined aluminium front panel and brushed enclosure reflect Luxman's commitment to build quality that matches the sonics.
