Pure Class A Input Stage
The input stage mirrors those found in many of the world’s best and most expensive amplifiers: a Class A topology composed of discrete FETs and powered by a semi-toroidal transformer. This pure analog stage preserves every last detail and every ounce of musicality, and properly amplifies and buffers the incoming signal so it’s ready to move on to the output stage.
Powerful, Efficient, Cool
The cool-running efficiency of the Class D output stage allows the DPA-1 to deliver maximum performance even in areas with minimal ventilation, such as equipment cabinets and closets. The DPA-1 runs at about 80% efficiency, compared to about 30% for a typical Class AB amp. Power consumption at idle is about 20 watts, compared to 100 watts or more for a Class AB amp with comparable power and sound quality.
