Overview
PrimaLuna EVO 300 Tube Integrated Amplifier
44 watts per channel. Remote-controlled triode switching. Pure tube amplification.
The PrimaLuna EVO 300 combines a tube preamplifier and power amplifier in one beautifully engineered chassis. Four EL34 output tubes deliver 44 watts per channel in ultra-linear mode or 24 watts per channel in triode mode, with switching available directly from the supplied remote.
Adaptive AutoBias simplifies tube ownership, while custom-wound transformers, point-to-point wiring, and premium internal components provide the foundation for a serious two-channel system. A dedicated tube headphone amplifier and transformer-coupled subwoofer outputs make the EVO 300 equally versatile for personal listening and full-range stereo playback.
