Stereophile - 2018 500 Recommended Components

Housed in matching casework, the Prime Power Supply can be used to power the Prime Headphone Amplifier. With engineering that was developed from the new generation of linear power supplies used in Meridian’s 800 Reference Series components, the Power Supply provides five 12V DC outputs with latching Mini-DIN connectors, plus a USB power output with an associated USB input, allowing USB audio to be passed through the Power Supply to a destination device – ideal for powering a DAC, for example. The Power Supply features multiple levels of regulation and acts as a high-quality, stable power source for the Headphone Amplifier and any audio devices requiring 12V/500mA or USB power. Centralising power to several devices, the separate supply allows improved performance from the devices it powers, providing a clean and noise-free supply.

Product Features:

  • High current, very low noise power supply delivers enhanced performance from a range of Meridian products including the Meridian Prime Headphone Amplifier, Audio Core 200, Meridian Director, Media Source 200, and other devices requiring a high-quality 12V power supply
