MC462 2-Channel Solid State Amplifier
 
450 Watts x 2 Channels
66% increase in Dynamic Headroom compared to previous model
Quad Balanced Design with McIntosh Autoformers™
 
Experience stereo bliss with the MC462 Amplifier. The MC462 replaces the highly regarded MC452 as our most powerful stereo amplifier. Like the MC452, it 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 Amplifier can single-handedly power a world class home audio stereo system.
"An extraordinarily well-engineered, exceptionally powerful amplifier... Highly recommended – insisted on, even." - Stereophile
 
The C53/MC462 combo sounded "super-smooth and superbly balanced at all times, whilst never letting the smoothness of their delivery interfere with their ability to resolve a level of detail, [which] means you will hear nuances you just will not hear with lesser amplifiers." - Audio Esoterica
 
The new generation MC462 stereo amplifier has received numerous updates compared to the previous model. 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 your favorite music with virtually no distortion. Bass performance is also improved as a result of the filter capacity increase. Our eco-friendly power management system, which will turn the amplifier off after a set amount of time when no input signal has been detected, has been added. Internal wiring and select circuit components have also been upgraded.
 
"A great amplifier not only in size but also in performance, capable of a refinement unthinkable for a beast of over 115 lbs (50 kg)." - Fedelta del Suono
 
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 appearance and color accuracy. 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.
