PrimaLuna EVO 300 Tube Integrated Amplifier

The PrimaLuna EVO 300 Integrated Amplifier represents the pinnacle of PrimaLuna's EVO series, offering exceptional performance, versatility and build quality for discerning audiophiles seeking the very finest valve amplification at its price point.

Exceptional Craftsmanship

Each PrimaLuna EVO 300 features meticulous handmade construction with a heavy-gauge, fully vented steel chassis finished with five coats, each hand-rubbed and polished.
