If you thought a McIntosh amplifier couldn't get more beastly than the highly lauded MC452, the company respectfully requests that you hold its beverage for a moment. The MC452 has been superseded by the new MC462 Quad Balanced Power Amplifier, a "Hulk Smash" beast of a machine that still boasts 450 Watts into any load (yeah, no, seriously--it doesn't matter if it's 2, 4, or 8?), but now boasts a 66 percent increase in dynamic headroom.

Other enhancements of the MC462 over the MC452 include a new eco-friendly power management system, upgraded internal wiring, and some tweaks to the circuit design.

For full details, read the press release below:

McIntosh, the global leader in prestigious home entertainment and ultimate-quality audio for over 65 years, is proud to announce the MC462 Quad Balanced Power Amplifier.

Experience stereo bliss with the new MC462 Quad Balanced Power Amplifier. The MC462 replaces the highly regarded MC452 as our most powerful stereo amplifier. Like the MC452, the MC462 features a robust output of 450 Watts per channel. With a dedicated McIntosh Autoformer connected to each audio channel, the full 450 Watts is available to any speaker regardless if it has 2, 4 or 8 Ohm impedance. Just one MC462 can single-handedly power a world class home audio stereo system.

The new generation MC462 has received numerous updates. The most prominent is that filter capacity has been increased by nearly 50%, which has resulted in a remarkable 66% increase in dynamic headroom from 1.8dB to 3.0dB. This allows the MC462 to easily handle drastic swings in dynamics and effortlessly reproduce music with virtually no distortion. Bass performance is also improved as a result of the filter capacity increase. Our eco-friendly power management system has been added, while internal wiring and select circuit components have also been upgraded.

Aesthetically, the MC462 retains all the hallmarks of a McIntosh amplifier with a few key modern enhancements. The front panel now utilizes direct LED backlighting that improves color accuracy and appearance. The two audio Autoformers and single power transformer are housed in new enclosures topped by a single machined cover with glass inserts. The back half of the amplifier is home to four of our Monogrammed Heatsinks which connect to advanced high current output transistors that help eliminate thermal equilibrium lag time.

Besides these updates, the MC462 is packed full of other exclusive McIntosh technologies to bring music to life including: Power Guard, Sentry Monitor, Quad Balanced design, Power Control, and our patented Solid Cinch speaker binding posts.

Balanced and unbalanced outputs make bi-amping or tri-amping speakers easier; they can also be used to send the audio signal to a secondary system or to connect a powered subwoofer. The MC462 sits on a beautiful polished stainless steel chassis and features the timeless McIntosh black glass front panel, illuminated logo, control knobs, aluminum handles and a pair of fast responding blue Watt meters.

Pricing and Availability
Orders for the MC462 can now be placed with Authorized McIntosh dealers with shipping expected to begin in July.
