Overview

The PrimaLuna EVO 400 Tube Power Amplifier is designed for systems that demand both muscle and refinement. Delivering substantial power in ultralinear mode and a more intimate, harmonically rich presentation in triode mode, it offers easy front-panel switching between two distinct sonic personalities. Adaptive auto-bias, dual-mono construction, and carefully specified transformers help maintain stability into real-world speaker loads. The EVO 400 can be used in stereo or bridged as a monoblock, making it a flexible cornerstone for high-end tube-based systems.

High-power tube amplification with finesse

The PrimaLuna EVO 400 Tube Power Amplifier delivers serious power reserves while preserving the natural warmth and dimensionality of tubes. With generous output transformers, adaptive auto-bias, and selectable ultralinear or triode operation, it combines authority and control with a smooth, engaging presentation.

Ultralinear and triode flexibility

At the touch of a button, listeners can switch between ultralinear mode for maximum power and dynamics or triode mode for a more intimate, saturated midrange. This flexibility lets the EVO 400 Power Amplifier adapt to different speakers, rooms, and musical tastes without changing hardware.

Overbuilt construction for demanding systems

Dual-mono layout, heavy-duty transformers, and robust power supplies allow the EVO 400 to drive difficult loudspeaker loads with composure. Comprehensive protection circuitry and PrimaLuna's adaptive auto-bias help extend tube life and keep performance consistent, making it a dependable choice for high-end stereo or monoblock configurations.
