Energize Your Gear

The EPX is Audionet’s scientifically proven answer to very serious music lovers desperately wanting to enhance the performance of their already existing devices with a High Performance upgrade.


The EPX produces clearly audible improvement in terms of stability, calmness, spatiality and tonal pureness. Music is reproduced with greater naturalness, clearer expression and in a brighter quality. Its straight design fits in every configuration.

Why does an external power supply represent such an improvement? The properties of active circuits are highly dependent on their supply voltages. Devices designed for the reproduction of music are very sensitive to any kind of external supply variations. As a voltage source, the EPX offers extremely precise and load-independent supply voltages. With these properties, EPX comes close to an ideal voltage source without accepting the disadvantages of accumulators.

The EPX achieves effective decoupling of all harmful influences from the public power supply system. The EPX is fed by a constant, low-noise source usually only used in laboratory environments. This precise constant voltage supply will really make the decisive difference to the performance of your devices.

Absolute Control

The EPX is built up as a high-precision constant voltage source. The chassis and circuit design are magnetically and capacitatively optimized. The symmetrical circuit board layout minimizes loss from oversized current paths and earths the current flow.

The arrangement of the toroid core transformers minimizes the influence of magnetic disturbances. The voltage supply is managed by two 200 VA ring toroid transformers that are each responsible for one half-wave. The capacity of the fast and impulse-stable high current capacitors is 576,000 uF. Only Schottky-diodes with extremely fast switching times are used. A highly constant and low-noise laboratory source serves as voltage reference.

The EPX is an external precision power supply & conditioner for Audionet electronic gear with a 5- or 7-pole socket. It is compatible with the following Audionet products:
