We’re proud to announce that the PrimaLuna EVO 400 Tube Power Amplifier has been named “Tube Power Amplifier of the Year” by The Absolute Sound Magazine.

This prestigious recognition highlights the exceptional performance, innovation, and craftsmanship that the EVO 400 delivers. We are incredibly proud of this achievement and want to extend our heartfelt thanks to everyone who has contributed to making this possible—our dedicated team, loyal customers, and passionate audiophiles around the world.

Thank you for believing in us and sharing our love for exceptional sound!

PrimaLuna's most powerful Evolution series amplifier delivers 70Wpc in ultralinear mode with the stock EL34 pentode, and almost 50Wpc with the optional KT150s. In pentode mode the power is reduced, at a mere 40 watts per channel, but many prefer this mode for its sound. The design is quite flexible: the KT150 is a beam tetrode, and the popular beam power tubes can safely be used. A market for matched current draw tubes exists in both pentode and ultralinear with ultralinear mode.

One of the many sonic advantages comes from the amps' soft-starting circuitry that delivers delayed heater and main B+ voltages. This enhances tube longevity and sound consistency while providing better sonics than any other method. It has PrimaLuna's custom-designed output transformers, which are the most powerful in the company's history. These are of the same quality of the EVO 300 but just larger, more powerful and more sophisticated.

These amps employ AC offset killer circuitry that is capable of over 100,000 hours of playback without loss of sound quality. PrimaLuna's tube amps are among the most gentle on tubes, extending their useful life.

The EVO 400 amplifiers are beautifully built and offer "dream system" performance while being extremely gentle on the wallet. At this pricing, the EVO 400 represents unbeatable value (JH).

Thank you all at The Absolute Sound Magazine. Also we want to thank Harmonia Distribution in the USA for making this achievement possible.
