The MC1.25KW module puts out 1,200 watts of pure power into one channel with an almost negligible total harmonic distortion of 0.005%. This surprising amount of power is fully available to 2, 4 or 8 ohm speakers through Autoformer ™ technology . A couple of these amplifiers can create home audio a system that can compete with almost any stereo system in the world. A 50% increase in filter capacity improves low frequency performance and increases dynamic range. The top of the amp features an updated but unmistakable McIntosh industrial design . The sonic Autoformer and powerful transformer remain positioned just behind front panel, but now they are stored in new glass covers. Among them is a new circular window that contains a badge with the name of the amplifier. The rear of the unit features 4 McIntosh Monogrammed Heatsinks ™. They are made of high- quality materials with excellent thermal conductivity properties . They connect to advanced high-current output transistors that eliminate the thermal balance time delay , so the first musical note played sounds just as good as songs played later in the listening session.
