McIntosh has announced the new MC611 Quad Balanced mono-block amplifier. Rated at 600 watts of power, the MC611 uses McIntosh's Autoformer technology the deliver the full 600 watts to the speaker, regardless if it has a two-, four-, or eight-ohm impedance. Compared with the previous MC601, the new model has double the filter capacity for an increase in dynamic headroom, it uses heavier-gauge internal wiring and upgraded circuit components, and it adds the company's eco-friendly power management system. Also, the cabinet design has some changes that are described in the press release below. The MC611 will be available this month for $7,500.
From McIntosh Labs
McIntosh is proud to announce the MC611 Quad Balanced Power Amplifier.
The monoblock MC611 Quad Balanced Power Amplifier produces 600 Watts of power - enough to satisfy nearly any loudspeaker. A pair of MC611s can easily drive an impressive home stereo system, or add additional units to power each speaker of a home theater. Utilizing our unique output Autoformer technology, the full 600 Watts will be delivered to the speaker regardless if it has 2, 4 or 8 Ohm impedance, allowing the MC611 to be used to its full potential.
The MC611 has received numerous updates and improvements compared to the previous MC601 model. Chief among them is that filter capacity has been doubled, which has resulted in a dramatic 55 percent increase in dynamic headroom from 1.8dB to 2.8dB. This twofold increase in filter capacity also helps improve the performance of low-end bass frequencies.
The front panel features new direct LED backlighting for improved appearance and color accuracy. On top, the audio Autoformer and power transformer are now contained in new glass topped enclosures. Behind them are two of our Monogrammed Heatsinks, which connect to advanced high-current output transistors that help eliminate thermal equilibrium lag time.
On the back, there continues to be three sets of our Solid Cinch speaker binding posts (one set for each speaker impedance), but space has been added between each set to allow for easier speaker cable connectivity. Other enhancements include heavier gauge internal wiring, upgraded circuit components and the addition of our eco-friendly power management system.
In addition to all these improvements, the MC611 remains full of other exclusive McIntosh technologies including Power Guard, Sentry Monitor, a Quad Balanced design and Power Control. Both a balanced and unbalanced output are included to 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 MC611 sits on a beautiful polished stainless steel chassis and features the timeless McIntosh aesthetic of a black glass front panel, illuminated logo, control knobs, aluminum handles and a large 8" (20.3 cm) fast responding blue Watt meter.
Orders for the MC611 can now be placed with Authorized McIntosh dealers with shipping expected to begin in February.
