Meridian’s Prime Power Supply is a reference-quality, high-current design based on the new linear power supplies developed for Meridian’s 800 Reference Series and specifically built for audio applications.

Meridian Prime Power Supply can be used to power a range of Meridian products, including the Meridian Prime Headphone Amplifier or Audio Core 200. The addition of Prime Power Supply to these components provides a significant enhancement in their performance – it’s like supercharging your car’s engine.
