Overview

The Reference A-300 continues Plinius' legacy of crafting world-class amplifiers, delivering powerful, pure sound with stunning aesthetics and enduring quality. As an evolution of previous models, every component has been meticulously refined, featuring upgraded electronics, low-noise audio-grade capacitors, and custom high-capacity power supplies, all housed in a modernized design that honors Plinius' signature style.

Built to immerse listeners in music, the A-300 combines immense power and depth with exceptional purity and clarity. As the pinnacle of the Plinius range, it pairs seamlessly with the Reference M-10 preamplifier to drive the finest high-end speakers with unmatched finesse.
