Technical Description
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 200 watts and an output current of greater than 25 amperes per chan- nel, makes this one of the most advanced and powerful am- plifiers 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.
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.
Design Philosophy
The design philosophy incorporated in the MC207 in- volved several different techniques, all based on sound sci- entific logic. Refer to figure 13. Every stage of voltage or current amplification 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 ex- pected from a McIntosh amplifier. The typical McIntosh owner would never accept the approximately 100 times
