Technical Description

Inside Bottom View of the MC303

McIntosh Laboratory, the company who introduced the

world’s first amplifier that could be called “High Fidelity”,

has done it again. The McIntosh engineering staff has cre-

ated a power amplifier without compromise, using the most

advanced McIntosh circuit design concepts.

A continuous average power output rating of 300 watts

per channel and with an output current of greater than 60

amperes per channel, making this one of the most ad-

vanced and powerful amplifiers McIntosh has ever manu-

factured. The distortion limits for the MC303 are no more

than 0.005% at rated power output for all frequencies from

20Hz to 20,000Hz. Typical performance at mid frequencies

is less than 0.0002%. The true distortion readings on the

MC303 are so low, it takes special measuring techniques

to make accurate readings. The MC303 can deliver the

best possible performance from any type of high quality

loudspeaker system.

Creating an amplifier with this level of performance did

not come easily. Many months of design, testing and mea-

suring were required. Extensive controlled listening tests,

the ultimate form of measuring, were made before the final

design was accepted.
