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
