Integrated amplifiers — PrimaLuna EVO 400

The EVO 400 is PrimaLuna's most accomplished current tube integrated amplifier, sitting at the top of the EVO lineup with comprehensive per-configuration specifications. The EVO 400 represents PrimaLuna's most ambitious current statement in tube integrated amplifier engineering.

Key specs that matter

Five single-ended inputs are provided. Input sensitivity ranges from 320mV to 370mV depending on tube configuration, with input impedance at a substantial 100,000 ohms single-ended. Gain ranges from 36.9dBu to 37.5dBu depending on configuration. Frequency response spans a wide 8Hz to 68,000Hz within plus-or-minus 3dB. Signal-to-noise ratio spans 90-98dB depending on configuration. Total harmonic distortion plus noise is under 0.1% at 1W. At 405 x 385 x 205mm and 31kg, the EVO 400 shares the EVO 300 Hybrid's chassis dimensions and mass exactly.

Sound and use context

Expect the warm, richly textured character tube amplification is broadly celebrated for, representing PrimaLuna's most accomplished current tube-informed integrated engineering ambition within the EVO lineup.
