300-Watt Audio Amplifier MJ15003 -MJ15004
When I began the design of this amp, my goal was to make a product better suited for the reproduction of complex music and voice. Although I emphasize the high electrical properties, the most important requirement is to create a superior sound, vivid images and superb spatial aural clarity.
Although the average level of listening is usually less than 10 watts, my design concept was to an amplifier with plenty of reserves, but the deviation is for Class A, at the height of the audience of cross-over distortion at a very low level. There is no place in the pathway, enhances the precision of the tonal characteristics of instruments and voices clearly. This Amplifier is virtually zero phase distortion over the audio range resolution is perfect and completely color the sound.
