You likely already know that monoblock amplifiers provide the top most quality sound. A monoblock amp uses a single amplifier system for single (“mono”) channel and an individual amplifier system for another channel. This is the prime advantage, because there is a minimal cross talk between the signals and results in no distortion of sound.
In recent years the power output in monoblock amplifiers has grown substantially. For example, the McIntosh MC1.2KW model produces an impressive 1,200 watts. By comparison, a typical home audio system might produce between 50 and 75 watts per channel.
For true audiophiles looking for the ultimate in sound reproduction (and a very significant budget) monoblock amplification is highly sought after, and for one primary reason: bi-amping. And McIntosh is a legend in amplification and found in many audiophiles sound system racks.
An audio signal contains the entire spectrum of audible frequencies. High frequencies, low frequencies and mid frequencies are all required to recreate the full tonality of music. But when both high and low frequencies travel down the same wire at the same time, they can interfere with each other in unexpected ways.
The solution is to separate the two signals via bi-amping, a process that greatly reduces interactions between the two signals. The internal crossover network in the speaker restricts low frequencies from traveling through the high-frequency wire, thus smoothing out the signal path for the tweeter.
Before you ask, bi-amping really doesn’t make the sound any louder … but it definitely makes it better, with cleaner, solid bass and more detailed highs.
