Overview
PrimaLuna EVO 400 Tube Integrated Amplifier
70 watts per channel. Eight EL34 tubes. One complete high-end stereo amplifier.
The PrimaLuna EVO 400 combines a vacuum tube preamplifier and power amplifier in a single chassis, delivering 70 watts per channel in ultra-linear mode or 38 watts per channel in triode mode.
With Adaptive AutoBias, remote-controlled operating modes, a dedicated tube headphone amplifier, and transformer-coupled subwoofer outputs, the EVO 400 offers the flexibility to build a serious two-channel system without separate preamp and power amplifier components.

Designed for Analog HiFi
The EVO 400 intentionally omits an internal DAC and phono stage, allowing you to select the digital source or external phono preamplifier that best suits your system. Its Home Theater Bypass also makes it possible to incorporate the amplifier into a combined stereo and home cinema setup.
