The PrimaLuna EVO 400 is a high-power tube integrated amplifier built around two sets of power tubes, so it can drive demanding speakers with strong control and wide dynamics. It updates the DiaLogue Premium HP with larger custom power supplies, an upgraded headphone amp that handles planar headphones, a refined autobias circuit and better Swiss-made capacitors. It suits listeners who want a warm, detailed tube sound with real low-end grip and are willing to accept tube maintenance and heat. Against cheaper tube integrateds it offers more power and build, and reviewers say it beats its own predecessor.

The PrimaLuna EVO 400 is a tube integrated amplifier. It builds on the DiaLogue Premium HP Integrated and uses two sets of power tubes to drive power-hungry speakers.
The custom power supplies are heavier than in the earlier model. The autobias circuit uses improved relays, and the amp circuits use Swiss-made capacitors of a higher grade than before.
It also has a headphone amp, which has been strengthened to drive demanding planar headphones.
