The MC1.25KW Quad Balanced Power Amplifier is one of our most advanced amplifiers. Redesigned from top to bottom, it replaces the venerable MC1.2KW as our most powerful single chassis monoblock amplifier. A simple glance at this 158 pound (71.7 kg) amp is enough to convey its power and performance capabilities, but when you hear it – then you’ll truly understand what it can do.
The MC1.25KW outputs 1,200 Watts of pure power into a single channel with a nearly imperceptible total harmonic distortion of 0.005%. This astonishing amount of power is fully available to 2, 4 or 8 Ohm speakers via our Autoformer™ technology. A pair of these amps can anchor a home audio system that can rival nearly any stereo system in the world.
The MC1.25KW is a fantastic amplifier with “unlimited dynamics, crushing power, accuracy, speed, authority, precise control, purity and transparency.” Recipient of Reference Award. – Hi-Fi Voice
Updates and enhancements abound in the MC1.25KW. A 50% increase in filter capacity improves the performance of low end frequencies as well as increasing dynamic headroom. The top of the amp showcases an updated yet unmistakable McIntosh industrial design that will fit right in with current McIntosh products or those made decades ago. The audio Autoformer and power transformer remain located just behind the front panel but are now contained in new glass topped enclosures. In between them is new circular glasswork housing the amplifier’s name badge that is adorned with a decorative trim ring.
The rear of the unit features 4 of our McIntosh Monogrammed Heatsinks™. Made from high quality materials with excellent thermal conductivity properties, these heatsinks are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo. They connect to advanced high current output transistors that eliminate thermal equilibrium lag time so that the first musical note played sounds just as good as songs played later in your listening session.
