Power amplifiers stereo — Luxman MQ-300

The MQ-300 is a distinctive tube-informed stereo power amplifier from Luxman, built with a substantial input impedance. The MQ-300 brings Luxman's meticulous engineering to dedicated stereo power amplification with a tube-informed character.

Key specs that matter

Input sensitivity is 490mV, with input impedance at a substantial 240,000 ohms single-ended. Frequency response spans 10Hz to 30,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is a strong 105dB, with total harmonic distortion plus noise at 1% at 100% global feedback - typical of a tube-informed design prioritising harmonic character. Maximum power consumption is 190W. At 460 x 237 x 340mm and 29kg, the MQ-300's considerable weight reflects serious internal transformer engineering consistent with quality tube-informed power amplifier design.

Sound and use context

Expect the warm, richly textured character tube-informed amplification is broadly celebrated for, consistent with Luxman's broader meticulous engineering philosophy applied to a tube-informed topology.

Pairing

Luxman's own preamplifier catalogue offers natural, brand-coherent pairings for a coherently voiced, entirely Luxman-based system.

Alternatives

Luxman's broader solid-state power amplifier catalogue offers alternatives for buyers preferring a more conventional measured-performance profile.
