The PrimaLuna EVO 300 Tube Preamplifier represents a turning point in performance within the EVO range, positioning itself as an absolute reference vacuum tube preamplifier.

Built on an extremely rigid, anti-resonant full-width chassis, the EVO 300 introduces a true Dual Mono configuration with completely separate power supply stages for the left and right channels. This architecture delivers extraordinary stereo separation, explosive micro-dynamics, and pinpoint soundstage imaging at an advanced audiophile level.

The signal path is fully hand-wired point-to-point using custom-specified silver-plated OFC copper conductors. The power supply stage utilizes dual vacuum tube rectification (2x 5AR4), paired with two custom high-efficiency toroidal transformers and choke filter inductors. This lowers the noise floor to imperceptible levels while imparting a warm, fluid, and holographic naturalness characteristic of the finest tube designs.

The EVO 300 integrates premium components throughout, including a motorized ALPS Blue Velvet volume attenuator, sealed relay input switches, and a sophisticated dedicated tube headphone amplifier with a 6.3 mm front-panel jack. Rounding out the features are an HT Pass-Thru input for multi-channel Home Theater integration and internal mounting capability for the optional PrimaLuna PhonoLogue phono stage.
