It is in the spirit of the Evolution series to push boundaries and contribute our experience to the art of audio reproduction. Here we bring together the latest innovations and the finest technologies to deliver a new level of performance to the emerging breed of Class D amplifiers. We have raised the switching frequency, reduced losses, eliminated thermal modulation, cleaned up the power supply, reduced mains pollution and built in immunity to common-mode noise, all packaged in a sleek, compact case that rivals amplifiers twenty times its size and weight. D-mono delivers thunderous power with none of its own sonic character. The perfect partner for the Sirens speakers, reimagining what is possible from compact components.
