Why Choose the PrimaLuna EVO 400 Tube Power Amplifier?

The PrimaLuna EVO

400 Tube Power Amplifier is designed to bring your music to life with unparalleled warmth and precision, redefining what a tube amp can achieve. Its innovative remote-controlled triode/ultra-linear switching lets you instantly switch between the lush, fuller sound of triode mode and the extended, powerful dynamics of ultra-linear mode—perfect for rediscovering classic rock, jazz, or 60s classical recordings with a sound that feels fresh and captivating.

The Adaptive AutoBias technology ensures low distortion (over 50% reduction) and extends tube life by monitoring and adjusting in real time, making maintenance effortless while delivering the lowest possible noise for breathtaking clarity.

PrimaLuna’s exclusive AC Offset Killer lowers transformer noise to unprecedented levels, creating a silent background that reveals every nuance— from the resonance of a violin string to the decay of a guitar note. The amplifier supports a wide range of tubes (EL34, KT88, KT150, and more), offering flexibility to customize your sound, while the Bad Tube Indicator protects your system by detecting failures instantly.

Switchable between stereo (70W per channel) and monoblock (140W per channel) operation, the PrimaLuna EVO 400 Tube Power Amplifier adapts to your setup, with 2, 4, and 8 Ohm taps for perfect speaker matching. Ideal for audiophiles seeking depth and musicality, this amp transforms every listening session into an immersive experience. Sound is subjective, though—the true test is in your ears.
