McIntosh MA6300 (Demo)
The MA6300 is the latest integrated amplifier, rich with all the premium technologies that McIntosh is famous for including Power Assurance System and Silent Electromagnetic Switching. With 100 watts per channel at 8-Ohms and 160 watts into 4-Ohm loads, the MA6300 can effortlessly power virtually any speaker from one of seven source selections: CD1, CD2, Tuner, Phono, Tape, TV and DVD.
Featured in the MA6300 is a dedicated, high performance headphone amplifier boasting low noise, extended frequency response and featuring ample gain to drive the finest quality headphones to life-like levels. A robust ¼” front panel jack is easily accessible and provides for years of personal listening enjoyment.
A pair of distinctive “blue eyes” output meters highlights the Fiber-Optic Illuminated Glass front panel from which the controls for Balance, Volume, Mute, Standby/On, and the seven Source Selection Buttons are all readily accessible. A turn on delay prevents annoying pops or thumps while protecting loudspeakers.
Only McIntosh can combine two basic audio components into a single instrument and still retain traditional McIntosh performance, quality and reliability. The MA6300 provides all of this in a more compact, space saving configuration. Those considering a McIntosh system for the first time will find the MA6300 a very comfortable place to start.
