The H120 uses the Hegel SoundEngine 2 amplifier platform allowing a damping factor higher than 2000 together with extremely low distortion levels. Details about the SoundEngine can be found on hegel.com. In many ways it works like a noise cancelling headphone. It compares the output of the amplifier with the input. It detects all the sound pollution (distortion), and plays this forward into the speaker output, but in reverse phase. Like 1 minus 1 equals 0. It cancels out all pollution in real time, leaving you with only the most natural sound. The SoundEngine technology has been developed over more than 30 years, from conception to where it is now. Millions of dollars were invested in initial development. It is what makes possible the sound performance for the money in the H120.
