Description
"The Power" by DPA (Digital Precision Audio / Deltec Precision Audio) is a legendary, passive RF (Radio Frequency) mains filter for Hi-Fi systems, originally manufactured in the UK. The device was specifically designed to isolate sensitive audio components—most notably digital-to-analogue converters (DACs) and preamps—from high-frequency interference on the power grid. Below is a technical and historical overview of this classic Hi-Fi component.
Design and construction:
High component density: Unlike simpler mesh filters that only use a couple of components, this small black metal chassis hides a very ambitious circuit. It is made up of about 14 inductors (coils)—some of which are hand-wound—and around 15 capacitors.
Connections
The device has a standard IEC power inlet (female) and an IEC power outlet (male). It connects as a link directly between the wall socket and your audio component.
Selective filtering
DPA designed "The Power" primarily as an aggressive low-pass filter to stop RFI (radio frequency interference) and grid-borne EMI (electromagnetic interference) to interfere with the audio signal.
Impact on sound
Among audio enthusiasts on forums, the filter is described as very effective in cleaning up the soundscape.
Excellent condition. Two units available.
