McIntosh Laboratory, the company who introduced the
world’s rst amplier that could be called “High Fidelity”,
has done it again. The McIntosh engineering staff has cre-
ated a power amplier without compromise, using the most
advanced McIntosh circuit design concepts.
A continuous average power output rating of 200 watts
and an output current of greater than 25 amperes per chan-
nel, makes this one of the most advanced and powerful
ampliers McIntosh has ever manufactured. The distortion
limits for the MC207 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
0.002%. The true distortion readings on the MC207 are so
low, it takes special measuring techniques to make accurate
readings. The MC207 can deliver the best possible perfor-
mance from any type of high quality Loudspeaker System.
Technical Description
Inside View of the MC207
Creating an amplier 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 nal
design was accepted.
Design Philosophy
The design philosophy incorporated in the MC207 in-
volved several different techniques, all based on sound
scientic logic. Refer to gure 13. Every stage of voltage
or current amplication must be as linear as possible prior
to the use of negative feedback. McIntosh engineers know
how to properly design negative feedback circuits so they
contribute to the extremely low distortion performance
expected from a McIntosh amplier. The typical McIntosh
owner would never accept the approximately 100 times
higher distortion of many non-feedback designs.
