To celebrate their 90th Anniversary, Luxman has produced the MQ-300, a low powered stereo amplifier, built to deliver the highest quality music performance.

Using a design akin to Luxman’s original MB-300 model of 1984, the company isn’t trying to reinvent the wheel, but just make it look and sound much better than before. Using original oil capacitors and various other design characteristics of the older model, the MQ-300 has been crafted to provide a full tone range of audio to make your music sound as natural as possible. Set in a walnut wood frame with a red piano lacquer finish and combined with a steel chassis, the MQ-300 is a terrific way for Luxman to celebrate their 90th Anniversary.

Independent left & right power supply circuit.

Extra thick, highly rigid chassis minimizes external vibration and resonance. 1.6 mm steel chassis, 2mm thick steel bottom plate and a 12mm aluminum top panel, ensures that the delicate audio signal will not be colored by external forces and will allow the music to be enjoyed unadulterated.
