LUXMAN L-509Z Integrated Amplifier

LUXMAN L-509Z Integrated Amplifier

The LUXMAN L-509Z is a flagship Z-Series integrated amplifier built on a “single-chassis separates” philosophy—pairing a fully discrete preamp and power amp in one elegant enclosure for true reference-level performance. It’s the first Luxman integrated to run LIFES 1.0 feedback modules in both the pre and power stages simultaneously, delivering exceptional musical detail, natural tonal richness, and a remarkably open soundstage. Power is effortless and controlled thanks to a robust Class AB output stage with a bipolar 4-parallel push-pull configuration, producing 120W + 120W into 8Ω and 220W + 220W into 4Ω for confident drive with demanding speakers.

Precision listening is elevated by Luxman’s LECUA-EX electronically controlled attenuator (88 fine steps), engineered to reduce sonic degradation while improving operational feel. The L-509Z also includes a serious onboard MM/MC phono stage with two-step MC gain (MC-H / MC-L), plus versatile connectivity for modern systems: multiple RCA and balanced XLR inputs, MAIN IN for external preamp integration, and dual PRE OUT for system expansion. Add refined usability—large analog VU meters, a 7-segment volume indicator, 3-band tone control (bass/middle/treble), a front-panel Mute button, and both 6.3mm and 4.4mm balanced headphone outputs—and the L-509Z becomes a centerpiece amplifier designed for serious, long-term listening.

The LUXMAN L-509Z is part of ListenUp's LUXMAN Integrated Amplifier Collection.
