Luxman M-700u Power Amplifier

Yes, the M-700u is bridgeable, allowing you to use it as a high-power monaural amplifier. In this mode, it delivers 420W into an 8Ω load for significantly increased power and headroom.

The amplifier operates in pure Class A for the first 6 watts of output. This ensures that low-level signals and delicate musical textures are reproduced with exceptional density and warmth before the amplifier transitions to its high-power push-pull operation.

With a high damping factor of 350 and a robust 550VA power transformer, the M-700u is designed to maintain tight control over speaker drivers. Its ability to deliver an instantaneous maximum output of 840W into 1Ω loads ensures it can handle demanding speaker impedances with ease.

ODNF (Only Distortion Negative Feedback) 4.0 is Luxman’s proprietary circuit technology. It provides the benefits of negative feedback—such as low distortion and high signal-to-noise ratios—without the phase-delay issues often associated with conventional feedback designs, resulting in a more natural and transparent sound.

Weighing 27.5kg, this unit is substantial and requires a sturdy, level surface capable of supporting its weight. It features resonance-dampening cast-iron insulator legs to minimize vibrations, but it should still be placed on a high-quality audio rack to ensure optimal performance.

Yes, the M-700u is equipped with both XLR (balanced) and RCA (unbalanced) inputs. You can select between these inputs via a switch on the rear panel, allowing for flexible integration with a variety of preamplifiers.
