ATM EPM-5NFB

Ideal Non-Feedback amplifier for recording studios and for use with very high efficiency loudspeakers. The amplifier is still entirely handcrafted by hand, welding the components manually on the printed circuit boards using tin and silver alloy. Once the PCB are finished, they are assembled in the aluminum box and adjust their parameters at intervals of time until reaching the maximum working temperature and, thus, achieve the most optimal result.

Two options for the power supply; Linear and switching.

The linear power supply uses a 200W toroidal transformer, high-speed rectifier and high-capacity, low-ESR capacitors.

The switched power supply uses two very low noise medical grade switching power supplies. One power supply for each channel achieving a much greater channel separation.

The power modules use audiophile-grade Nichicon and Wima capacitors. The resistors are very low tolerance.
