The EVO 100-4 is a tube-informed stereo power amplifier from PrimaLuna, sharing the EVO 100 integrated amplifier's electrical foundation within a dedicated power-amplifier-only format. The EVO 100-4 brings PrimaLuna's considered engineering to dedicated stereo power amplification.
Key specs that matter
Input sensitivity is 880mV, with input impedance at 100,000 ohms single-ended. Output power is 40W or 45W in stereo mode. Gain is 28dBu. Frequency response spans a wide 10Hz to 95,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 92dB, with total harmonic distortion plus noise at 0.2% at 100% global feedback. Maximum power consumption is 280W. At 405 x 280 x 190mm and 17kg, the EVO 100-4 maintains a manageable power amplifier chassis.
Sound and use context
Expect the warm, richly textured character tube amplification is broadly celebrated for, with the strong 92dB signal-to-noise figure consistent with PrimaLuna's broader considered tube-informed engineering philosophy.
Pairing
PrimaLuna's own preamplifier catalogue, including the EVO 100-3, offers natural, brand-coherent pairings within the same broader catalogue.
Alternatives
PrimaLuna's own EVO 200-4 offers a somewhat more powerful alternative within the same broader power amplifier catalogue.
