"The Next Generation of Awesome": Japanese-Built Luxman L-507Z Integrated Amplifier Includes Distortion-Canceling Engine, Comprehensive Feature Set

The L-507Z integrated amplifier, the first entry in Luxman’s new Z Series of audio gear, sets a high bar. Outputting a true 110Wpc, this beautiful-looking and -sounding component is also the first to tout the company’s LIFES 1.0 distortion-canceling feedback circuitry, which fosters stellar dynamics and reduces distortion in the amplification stage to less than half the level of its previous ODNF system. A brand-new electronically controlled 88-step LECUA1000 attenuator integrated into the amplifier circuit for minimal degradation; custom-made EI-type power transformer and large-capacity filter capacitors (10,000μFx 8) for instantaneous current delivery; beeline construction for the shortest signal paths; and low -resistance, parallel-configured speaker relays are just a few of the other technological assets on hand.  

Combined, those obsessive details — and hallmark Japanese build quality that alone tells you that you own something special and made to last — allow L-507Z to perform like a pair of high-end separates. Such are the degrees of naturalism, presence, detail, tonality, and expressiveness with which you’ll enjoy your favorite recordings — not to mention the curiosity you’ll have when you play new fare. A spectacular MM/MC phonostage, parallel headphone outputs, two pairs of balanced XLR inputs, four line-level inputs, a preamp output, and trigger controls speak to the comprehensive versatility L-507Z brings to any system. Another invaluable touch found on few audiophile amplifiers: sensitive tone controls, balance controls, and loudness function. You might be surprised how handy they become. 

On the elegant exterior, a pair of back-lit needle-type VU meters centers a blasted-white-finished front panel that includes defeatable 7-segment LEDs that display the volume level, two hefty knobs, four smaller switches, and five buttons. The loop-less, rectangular aluminum chassis hosts a hairline-finished top panel with large ventilation slots for sufficient air flow and excellent heat dissipation. L-507Z’s superb stability gets another boost from cast-iron feet that damp vibrations and defeat resonance. 

On the subject of quiet: For a 56-pound unit that drives practically any speaker and throws 110Wpc, L-507Z operates with admirable silence — something you’ll especially notice during quiet passages and low-key material. The upshot: You’ll experience the subtle nuances, low-level information, and ambience that help bring recorded music to life. Or, as TONEAudio founder Jeff Dorgay notes: “Whether listening to analog or digital sources, you’ll hear more.”

The 7.0 x 17.3 x 17.9-inch (HWD) L-507Z comes with a brick-solid aluminum remote control, power cable, and three-year warranty. If you have any questions, or want to talk in further detail about any of Luxman’s outstanding audio line, please call a Music Direct audio consultant. 

“If the combination provided by the L-507Z ticks all the boxes on your list, there’s no better choice.”

“Your thoughts turn to the artistry and beauty of the music, and soon abandon worries about technology and power.”
—The Absolute Sound, 2024 Recommended Product 

"Its sound is beyond reproach, being at once linear and dynamic, highly engaging yet non-fatiguing."

Innovative Engineering

A highly stable, custom power transformer and newly developed, large-capacity filter capacitors (10,000μFx 8) are combined in the power supply unit, which provides instantaneous current supply and voltage stability. The damping factor has also been improved by direct wiring to the speaker terminals using Luxman's proprietary OFC wire for natural signal transmission.

LIFES 1.0 Feedback Engine

LIFES is based on the technical concept of Luxman's ODNF circuit and realizes excellent, dynamic characteristics without feeding back any of the original audio input signal to the main amplifier, achieving remarkably natural sound. The design has been conceived and expanded upon using simulation technology and painstaking research. By repeatedly auditioning, rigorously scrutinizing, and combining specially selected components, the engineering team at Luxman has achieved supreme performance characteristics. 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 that of the previous system. The output stage features a three-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, creates a natural soundstage, full of energy, to confidently drive any compatible loudspeaker system.
