This unique power supply technology is now available for use with a wide variety of equipment. It is a stand alone power supply intended to upgrade the sonic performance of the audio component to which it is connected.
The power supply circuits in the majority of audio equipment tend to be based on the usual transformer, bridge rectifier, storage capacitor, voltage regulator topology. The electronic components used are generally of standard quality and provide adequate performance for the majority of people. Each of these components can be upgraded to ‘audiophile’ quality to gain significant improvement in sonic performance, but no matter how good the upgrade there will still be the influence of mains pollution percolating through and spoiling the end result. This is the reason that ‘Never Connected’ technology was developed. By isolating the voltage regulation circuits during the conduction cycle of the bridge rectifier, most if not all of the effects of mains pollution can be eliminated. The end result is a vast step forward in sound quality.The box contains a printed circuit board with one toroidal mains transformer and two ‘Never Connected’ circuits, one positive voltage and the other a negative voltage. Each of the ‘Never Connected’ circuits is followed by a High Performance Voltage Regulator circuit (super regulators if you prefer) to provide a stable, low noise, wide bandwidth output voltage.
