Power amplifiers stereo — Luxman M-700u

The M-700u is a stereo power amplifier from Luxman, built with an exceptional damping factor and wide bandwidth. The M-700u brings Luxman's considered engineering to two-channel power amplification.

Key specs that matter

Input sensitivity is 1,100mV, with input impedance at 34k ohms balanced or 51k ohms single-ended. Output power is 120W into 8 ohms, rising to 210W into 4 ohms. Gain is 29dBu. Frequency response spans an extraordinary 1Hz to 130,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 115dB, with total harmonic distortion plus noise at 0.1% with full global feedback, maximum power consumption at 370W, and a remarkable damping factor of 350 - an exceptional figure indicating outstanding control over connected loudspeaker driver movement. At 440 x 190 x 427mm and 27.5kg, the M-700u represents a substantial stereo amplifier commitment.

Sound and use context

Expect exceptional power delivery combined with outstanding control reflecting the remarkable damping factor of 350, combined with the strong 115dB signal-to-noise figure and extraordinarily wide 1Hz-130kHz bandwidth.

Pairing

The substantial 120/210W output combined with the exceptional damping factor suits demanding, revealing loudspeaker loads directly, and Luxman's own C-10X or C-900u preamplifiers share the brand's coherent engineering philosophy.

Alternatives

Luxman's broader amplifier catalogue offers alternatives for buyers wanting a different output level within the same considered Japanese engineering philosophy.
