Overview
PrimaLuna EVO 300 Tube Power Amplifier
44 watts per channel. Triode and ultra-linear operation. Upgradeable to monoblocks.
The PrimaLuna EVO 300 brings the flexibility of a high-end tube power amplifier to a thoughtfully engineered stereo design. With four EL34 output tubes, it delivers 44 watts per channel in ultra-linear mode or 22 watts per channel in triode mode. Switch between the two using the supplied remote control to suit your music and listening preferences.
As your system evolves, the EVO 300 can be converted to monoblock operation, delivering 85 watts in ultra-linear mode. Adaptive AutoBias, custom-wound transformers, and premium point-to-point wiring make it a compelling foundation for a dedicated two-channel system.
