MC611 1-Channel Solid State Amplifier

MC611: £10495

  • 600 Watt Quad Balanced Monoblock

  • 55% increase in Dynamic Headroom compared to the previous model

The monoblock MC611 Quad Balanced Power Amplifier produces 600 Watts of power – enough to satisfy nearly any loudspeaker. A pair of MC611s can quickly drive an impressive home stereo system or add more of them to power a home theatre. Thanks to our unique output Autoformer™ technology, your speakers will receive a total of 600 Watts regardless of whether they have 2, 4 or 8 Ohm impedance, allowing you the ability to use the MC611 to its full potential.

"The MC611 is one of the most beautiful sounding amplifiers I’ve ever heard, and at the same time, is one of the most realistic sounding amplifiers I’ve ever heard. And this continues to blow me away every time I turn the MC611s’ power on." Winner of Best of 2018 Blue Note Award. - Enjoy The Music

The MC611 has received numerous updates and improvements compared to our previous 600-watt monoblock model. Chief among them is that filter capacity has doubled, resulting in a dramatic 55% increase in dynamic headroom from 1.8dB to 2.8 dB. This twofold filter capacity increase also helps improve low-end bass frequencies' performance.

We have made many technological and engineering advancements to our amplifiers over the years.

"The MC611s offer massive power with minimal distortion at all frequencies into any load. In doing so, they are virtually unique… Easy going silky smooth sound, richly detailed and dynamically awesome." Awarded 5 out of 5 Globes. - Hi-Fi World

The front panel features new direct LED backlighting for improved appearance and colour accuracy. On top, the audio Autoformer and power transformer remain seated just behind the front panel but are now contained in new glass-topped enclosures. Behind them are 2 of our Monogrammed Heatsinks™, which connect to advanced high-current output transistors that help eliminate thermal equilibrium lag time. A screening of the amplifier’s block diagram has been added to the panel between the heatsinks.

"Attack, sustain, decay came through with such clarity and power you – I – rarely hear through high-power amplifiers... Highly Recommended, A++++." - Audiophile Style

On the back, there continue to be three sets of our Solid Cinch™ speaker binding posts (1 set for each speaker impedance); more space has been added between each set to allow for easier speaker cable management. Our eco-friendly power management system, which will turn the amp off after a set amount of time when no input signal has been detected, has also been added. Other enhancements include heavier gauge internal wiring and upgraded circuit components.

"A rare combination of effortless power and sophistication" allows it to easily "drive almost any type of speaker." Highly Recommended: 6 Stars - Lyd & Bilde

In addition to all these improvements, the MC611 is full of other exclusive McIntosh technologies:

  • Power Guard® monitors and adjusts the input 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 for effortless system power-up and shutdown

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.

"Natural, effortless control of dynamic swings, a linear power response throughout the frequency range, a true sense of fidelity to the recorded event, a Muhammed Ali-like speed and power propelling every note, deep authentic bass and a wonderfully human and palpable midrange with an organic, yet polished aural touch." - AudioStream

The MC611 sits on a beautiful polished stainless steel chassis. It features the timeless McIntosh aesthetic of a black glass front panel, illuminated logo, control knobs, aluminium handles and of course, a large 8” (20.3 cm) fast-responding blue Watt meter.
