Pure ‘Class A’ Makes Music Magic


Japanese high-end audio specialist delivers its finest integrated amplifier yet, operating in pure Class A mode to deliver an addictive musical rush

Luxman, one of the world’s oldest and most revered audio manufacturers, enters its tenth decade of audio excellence with the arrival of the L 590AXII – the best integrated amplifier the company has ever produced.

Beautifully built with a classic look and feel, the amp operates in pure Class A – a Luxman speciality – to deliver spellbinding clarity, exquisite sonic detail and fluid, free-breathing musicality.


The L 590AXII is the culmination of all that Luxman has learned since launching Japan’s first high-quality integrated hi-fi amplifier, the valve-based SQ5A, in 1961.

It combines the enduring excellence of Class A operation – still considered by many audiophiles to represent the pinnacle of sonic fidelity – with the convenience of a single-chassis integrated design, plentiful facilities and uncompromised engineering both inside and out.

At the amp’s heart lies Luxman’s fourth-generation ODNF (Only Distortion Negative Feedback) circuit, sporting a three-parallel push-pull structure with three-stage Darlington.

This restricts feedback to distortion components only, enabling a fast primary slew rate, ultra-wide bandwidth and enhanced signal-to-noise performance.

The preamp section borrows much technology from Luxman’s flagship C-900u preamplifier, including the LECUA 1000 attenuator circuit, which provides an extremely fine degree of volume control and left/right balance adjustment whilst maintaining sound quality at the highest level.

Power is rated at 30W per channel into eight ohms, doubling to 60W per channel into four ohms – a healthy output for a pure Class A design, with sufficient power on tap to drive any loudspeakers of suitable quality.


The L 590AXII’s high-inertia power supply circuit features a substantial transformer with plentiful regulation, ensuring an unshakable response to load fluctuations.


A high-capacity block capacitor contributes to the amp’s ability to deliver abundant power instantaneously yet remain firmly in control, while its low-impedance transmission design, carefully selected custom components and short, fully optimised signal paths deliver maximum sonic fidelity.

Exceptional signal purity doesn’t have to mean stripped-to-the-bone facilities – not when they are implemented with Luxman’s no-compromise approach. The L 590AXII includes precision bass and treble tone adjustment (extremely useful given the variability of today’s music formats), a ‘loudness’ control for low-level listening, a ‘line straight’ button that bypasses the tone controls, and phase selection for the balanced inputs.

Turntable users are well catered for, as befits the current vinyl revival, with an excellent onboard phono stage switchable for MM and MC cartridge types. A high-quality headphone output is also included.

In classic Luxman style, the L 590AXII’s fascia sports two illuminated VU meters, one for each channel, giving a real-time indication of signal level that is both a satisfying visual accompaniment to the music and a useful guide to how hard the amp is being pushed.

Around the back are six line-level inputs (four single-ended RCA and two balanced XLR) alongside the phono input for turntables, plus two sets of heavy-duty speaker binding posts.


Also present are record-out, monitor-in and pre-out terminals, an external preamp input for integration with an AV system, and two remote output terminals for integrated system control.

Build quality is exemplary, as it is throughout the Luxman range, right down to the cast-iron, resonance-reducing feet.

The Luxman L 590AXII integrated stereo amplifier is available now. along with the matching CD player Luxman D-06U.



The history of the LUXMAN audio brand began in 1925, at the birth of radio broadcasting. LUXMAN has paid particular attention to the world of audio and has gained high reputation as a quality brand of high-end audio products both domestically and internationally. People tend to open their mind to natural things and react negatively to the unnatural. Natural sound, without coloration, develops an intimacy between the music and the listener. Naturally and purely reproduced music resonates with the listener’s imagination. LUXMAN reflects this effect in our product development. Music that features a performer's true passion and which a recording engineer has worked on precisely benefits from the fine nuances in sound which LUXMAN aims to reproduce, conveying the sprit of the artist and the enthusiasm of the performance. They strive to bring to the listener the experience of unlimited, pure music. Composers, performers and recording engineers have poured their true feelings into our favorite pieces of music. LUXMAN would be satisfied if the listener could experience those same passions through our products. LUXMAN has celebrated its 90th anniversary and hopes to discover new excitement through wonderful music and to continue to share that pleasure with everyone.
