The D08C-1B is a pPower sSupply designed by ESD Acoustic especially for its patented fField Ccoil dDrivers.

Pairing with ESD Acoustic’s driver units, it features five channels of direct current output. It employs multiple field-effect transistors along with wide copper traces and the exceptional performance of a switching power supply. This configuration ensures a constant and clean current supply to the field coils, providing ESD Acoustic’s driver units with robust driving force.

The D08C-1B uses a pioneering switching power supply to achieve AC-DC conversion. It can operate within a wide voltage range of 80-280V, completely resolving the power supply challenge that audiophiles find most difficult to address.
