Luxman M-700U


The M-700u power amp is the perfect partner for the C-700u, drawing upon Luxman’s decades of experience in amplifier design to deliver an exquisite combination of rich sonic expression, fine detail, wide bandwidth and dynamic gusto. Stereo output is rated at 120W per channel into eight ohms and 210W per channel into four ohms, achieving up to 840W per channel into one ohm instantaneously. There is also a user-selectable mono mode with a rated output of 420W into eight ohms.


In order to achieve this level of power without sonic compromise, Luxman has implemented its ODNF 4.0 drive circuit utilising a four-parallel push-pull structure with three-stage Darlington. A Luxman ‘Ultimate Efficiency Power Transformer’ – an EI type rated at 550VA – forms the heart of the amp’s power supply, with plentiful regulation ensuring an unshakable response to any load fluctuations. A high-capacity block capacitor contributes to the M-700U’s ability to deliver lashings of power instantaneously yet remain firmly in control, while the amp’s low-impedance transmission design, carefully selected custom components and short, fully optimised signal paths deliver maximum sonic purity


In classic Luxman style, the M-700u sports two illuminated VU meters, one for each channel, giving a real-time indication of signal level that’s both a satisfying visual accompaniment to the music and a useful guide to how hard the amp is being pushed. Around the back are both single-ended RCA and balanced XLR inputs, heavy-duty speaker binding posts, switches for stereo/mono modes and phase inversion, plus a remote input terminal for custom installations.

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.
