The PrimaLuna EVO 100 Tube Preamplifier represents the gateway to high-fidelity tube preamplification by PrimaLuna.

Designed according to the Dutch brand's rigorous construction philosophy, the EVO 100 delivers the warmth, holography, and transparency typical of vacuum tubes, combined with extraordinary reliability and superior mechanical craftsmanship.

The signal path is fully hand-wired point-to-point using silver-plated OFC copper wire. Unlike many entry-level tube preamplifiers that use solid-state rectifiers to cut costs, the EVO 100 features a dual-tube vacuum rectifier stage (2x 5AR4)—a design detail usually reserved for ultra high-end components—ensuring unrivaled soundstage three-dimensionality and listening smoothness.

The package is completed by custom, in-house designed low-noise toroidal power transformers, a high-precision motorized ALPS Blue Velvet volume attenuator, and a dedicated high-quality tube headphone amplifier.
