The MC1.25KW Quad Balanced Power Amplifier is McIntosh's newest and one of their 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 speakersvia our Autoformer™ technology. A pair of these amps can anchor a home audio system that can rival nearly any stereo system in the world.

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.

Other exclusive McIntosh features included in the MC1.25KW include:

Power Guard® that monitors and adjusts the output signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker damaging clipping

Sentry Monitor™ – our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return tonormal

Quad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signal

Power Control to send power on/off signals to other connected McIntosh components (such as CD Players, turntables, tuners​ and media streamers​) for easy system power up and shutdown

Patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables​ to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables

Both a balanced and unbalanced output are included to make bi-amping or tri-amping your speakers easier; they can also be used to send the audio signal to a secondary system if your preamplifier does not have enough outputs or to connect a powered subwoofer.
