McIntosh is pleased to introduce the MC611 Quad Balanced Power Amplifier, which replaces the MC601.
Not just a simple refresh of the MC601, the MC611 features notable improvements. Chief among them is that filter capacity has been doubled, which has resulted in a dramatic 55% increase in dynamic headroom from 1.8dB to 2.8dB. This two-fold increase in filter capacity also helps improve the performance of low end bass frequencies.
Both a balanced and unbalanced output are included to facilitate speaker bi-amping or tri-amping; they can also be used to send the audio signal to a secondary system if the preamplifier does not have enough outputs, or to connect a powered subwoofer. Like the MC601, it outputs 600 Watts into a single channel.
