1,200 Watt Quad Balanced Monoblock
Redesigned from top to bottom
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, 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 energy is available to 2, 4 or 8 Ohm speakers via our Autoformer™ technology. A pair of these amps can anchor a home audio system rivalling nearly any stereo system worldwide.
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 low-end frequencies' performance and dynamic headroom. The amp's top 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 behind the front panel but are now in new glass-topped enclosures. Between them is new circular glasswork housing the amplifier’s name badge 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 sounds as good as songs played later in your listening session.

The heatsinks are capped with handsome ventilation trim plates. These trim plates and the circular trim ring are made from aluminium and are finished to match the front panel handles.
The MC1.25KW will drive most speakers "with divine power and control... [and] a dynamic contrast we have never heard before." Highly Recommended: 6 Stars - Lyd & Bilde
The AC receptacle has been repositioned to provide additional clearance so a wider assortment of power cords can more easily be used. All this sits atop a polished stainless steel chassis, which rests on four newly redesigned feet with a chamfered edge. Other updates include an updated power transformer, heavier gauge internal wiring, upgraded circuit components, and the addition of our power management system that will turn the amp off after a set amount of time when no input signal has been detected.
Regardless of genre, music "was presented with ease and a silk-smooth refinement," yet the MC1.25KW's "pace, rhythm, and timing were spot on... expertly engineered, skillfully assembled, full of top-quality parts, and made of some of the best materials available... Enthusiastically recommended!" - SoundStage Ultra
With all the changes and improvements made in the MC1.25KW, one thing that hasn’t changed is the large, fast-responding 11” (27.9 cm) blue-watt meter that accurately shows the amp’s power output. Also unchanged is the signature black glass front panel with control knobs, illuminated logo, and aluminium end caps with handles. The front panel and meter have new direct LED backlighting for improved appearance and colour accuracy.
Other exclusive McIntosh features included in the MC1.25KW:
Power Guard® 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 the current exceeds safe operating levels and then resets automatically when operating conditions return to normal
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
Our patented Solid Cinch™ speaker binding posts 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.
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 connect a powered subwoofer.
