Hi. Here on of my newest project. It is a fully dual mono all discrete FET headphone amplifier in Class-A. Real Class-A at 100ma per supply, and channel. With supplies of +/-18V it is really cooking
It sounds superb, perfectly silent with dual fully discrete low noise regulators with CRC pre-filters. The case was made by Front Panel Express, side wood panels in exotic Padouk wood with oil finish.
The circuit is DC coupled, with no coupling capacitor in the signal path. A servo takes care of the circuit small
Here the prototype pictures
