Luxman MQ-300 Vacuum Tube Stereo Power Amplifier

The MQ-300, a vacuum tube stereo power amplifier from LUXMAN, uses thoroughly selected parts and circuits to maximise the performance and tonal quality of the latest direct heated triode the TA-300B following in the design footsteps of the masterpiece MB-300 released 31 years ago. Since the foundation of the company 90 years ago, LUXMAN has pursued core principles for sound creation, honest and natural sound quality and feeling the sound field without exaggeration, feeling the unity of sound with sufficient data for the whole audio band, fatigue free listening enjoyment, all of which are embodied in the MQ-300. By expressing the original sound, the MQ-300 brings the spirit of music inscribed in your favourite discs to life.

For vacuum tubes design where electrons fly about, external vibration and resonance can be great enemies that can interfere with sound signal transmission. The MQ-300 combats this with a high rigidity chassis structure that combines a 1.6mm thick steel chassis, 2mm thick bottom board and a 12mm thick top panel to block such vibrations.
