The MA-6300 is the latest integrated amplifier, rich with all the premium technologies that McIntosh is famous for, including Power Assurance System and Silent Electromagnetic Switching.

What's included in the box


The MA6300 is the latest integrated amplifier from McIntosh, rich with the features, benefits and power that McIntosh is famous for such as Power Guard, Thermal Protection and Electromagnetic Switching.

With 100 watts per channel into 8 ohms and 150 watts per channel into 4 ohms the MA6300 can effortless power virtually any musical passage from any one of its seven source selections; CD1, CD2, Tuner, Phono, Tape, TV and DVD.

The MA6300 utilizes the latest output transistor. ThermalTrakTMoutput transistors instantly and accurately monitor their operating temperature and adjust bias as needed resulting in low distortion at all power levels without excess heat. The MA6300 runs cooler than many integrated amplifiers even at peak levels.

The trademark “Blue Eyes” output meters grace the glass front panel along with controls for Balance, Volume, Mute,Standby/On, ¼” Headphone Jack and the Seven Source Selection Buttons. A turn on delay prevents pops or thumps generated in other equipment from causing annoying noises or damaging speakers.
