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.\u003c\/p\u003e\u003c\/section\u003e\n\u003csection id=\"section-1\" class=\"mc-section\"\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003c\/section\u003e\n\u003cfigure class=\"mc-img-block\"\u003e\u003cimg src=\"https:\/\/www.mcintoshlabs.com\/-\/media\/images\/mcintoshlabs\/products\/productimages\/mc125kw\/mc125kw-1283qcadobergb.jpg?rev=7b41a432f55248f889fe643e1f9d450e\u0026amp;revision=7b41a432-f552-48f8-89fe-643e1f9d450e\" alt=\"McIntosh MC1.25KW Amplifier\" loading=\"lazy\"\u003e\u003c\/figure\u003e\n\u003csection id=\"section-2\" class=\"mc-section\"\u003e\u003cp\u003eThe 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\u003c\/p\u003e\n\u003cp\u003eUpdates 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.\u003c\/p\u003e\u003c\/section\u003e\n\u003cfigure class=\"mc-video-block\"\u003e\u003cvideo autoplay loop muted playsinline poster=\"https:\/\/www.mcintoshlabs.com\/-\/media\/videos\/mcintoshlabs\/short---monogrammed-heatsinks02-thumbnail.jpg?rev=23b4b882b1314a3caf9ddace1bd7539b\u0026amp;revision=23b4b882-b131-4a3c-af9d-dace1bd7539b\"\u003e\u003csource src=\"https:\/\/www.mcintoshlabs.com\/-\/media\/Videos\/McIntoshLabs\/Short---Monogrammed-Heatsinks02-1280.mp4?rev=853ee0f43d924b8089b499b6ae6370e4\u0026amp;revision=853ee0f4-3d92-4b80-89b4-99b6ae6370e4\" type=\"video\/mp4\"\u003e\u003c\/video\u003e\u003c\/figure\u003e\n\u003csection id=\"section-3\" class=\"mc-section\"\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003c\/section\u003e\n\u003csection id=\"section-4\" class=\"mc-section\"\u003e\u003cp\u003eThe heatsinks are capped with handsome ventilation trim plates.

All of this sits atop a polished stainless steel chassis which rests on 4 new redesigned feet that feature 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.\u003c\/p\u003e\n\u003cp\u003eRegardless 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\u003c\/p\u003e\u003c\/section\u003e\n\u003csection id=\"section-6\" class=\"mc-section\"\u003e\u003cp\u003eWith 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 aluminum end caps with handles.
