McIntosh has announced the monoblock MC611 Quad Balanced Power Amplifier, which can produce 600 Watts of power; or use a pair to drive a home stereo system, or add units to power each speaker of a home theatre.
Using the company's output Autoformer technology, the full 600 Watts will be delivered to the speaker regardless of 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 55% 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 colour accuracy. On top, the audio Autoformer and power transformer are now contained in new glass topped enclosures. Behind them are two 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 an eco-friendly power management system.
In addition to all these improvements, the MC611 includes other exclusive McIntosh technologies, including Power Guard, Sentry Monitor, a Quad Balanced design, and Power Control. Both a balanced and unbalanced output is 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 polished stainless steel chassis and features 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 McIntosh MC611 can now be placed with authorized McIntosh dealers with shipping expected to begin this month. The MSRP is US$7,500.
