Stereo Amplifier with ADH™ Technology

ADH™ Technology provides the best of two worlds: the linearity of the most acclaimed analog amplifiers (Class A) with the power, efficiency and compactness of digital amplifiers (Class D).The principle of ADH™ Technology is as follows:

A genuine class A amplifier directly connected to the speaker drives the output voltage: as the master, it sets the sound of the whole ADH core.

A digital amplifier is added in parallel to provide most of the current to the speaker. It is slaved to the analog amplifier so that it minimizes the current of class A.

High-quality Digital-to-Analog Conversion

The D-Premier incorporates a very high quality DAC at its core. In the DAC, the output current of a high performance device is directly converted into high voltage without any processing in between: no operational amplifier, no current mirror. Instead, a fully original very complex leak-less path is designed to carry the original current of the DAC to the only two ultra high-linearity resistors in the system.

Flexibility, Sustainability

The D-Premier is the first fully upgradable high-end amplifier. It was conceived to be able to evolve and adapt with time. Such continuity and sustainability has been achieved thanks to the unique importance of software in the amplifier. The D-Premier is a software-driven hardware analog platform.

The 5.3 Firmware improved the power supply, resulting in increased extension and tremendous bass slam.

Along with the 5.5 Firmware update, came the addition of a hardware card which enables WiFi digital streaming.

NEW !! 5.3 and 5.5 Firmware Available
