McIntosh MC1.25KW Quad Balanced Power Amplifier

The MC1.25KW Quad Balanced Power Amplifier is one of McIntosh's most advanced amplifiers. Redesigned from top to bottom, it replaces the venerable MC1.2KW as Mc's 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 McIntosh 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 audio Autoformer and power transformer remain located just behind the front panel but are now contained in new glass topped enclosures.
The rear of the unit features 4 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.
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” 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. The front panel and meter have new direct LED backlighting for improved appearance and color accuracy.

Features

  • Power Guard® that monitors and adjusts the output signal at the speed of light and makes real time adjustments to prevent potentially damaging clipping
  • Sentry Monitor™ - Mc's fuseless short-circuit protection circuit that disengages the output stage before 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
  • Power Control to send power on/off signals to other connected McIntosh components for easy system power up and shutdown
  • Patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables; the binding posts are gold-plated to prevent corrosion
