PrimaLuna EVO 400 Tube Power Amplifier - Black

The PrimaLuna EVO 400 is a stereo power amplifier designed to offer power, musical refinement, and great reliability. The craftsmanship of its construction combines with advanced technical solutions, resulting in a high-end component intended for enthusiasts who want to enhance every nuance of their music.

The circuitry uses entirely hand-made point-to-point wiring, combined with carefully selected components and generously sized transformers. This configuration allows the EVO 400 to confidently drive numerous types of speakers, always maintaining a natural, dynamic and musically engaging reproduction.

The possibility of choosing between Ultralinear and Triode operation also allows you to adapt the amplifier's character to personal preferences, the genre of music you listen to and the characteristics of your system.

An engaging and nuanced reproduction

The PrimaLuna EVO 400 stands out for its accurate tonal balance and its ability to deliver music with body, depth and realism. The midrange is particularly expressive: voices gain presence and consistency, while acoustic instruments maintain their color and natural harmonic richness intact.

The higher frequencies are bright, airy and detailed, without ever becoming fatiguing. The bass register, on the other hand, is solid, well-controlled, and capable of precisely tracking even the most complex and dynamic musical passages.

Spatial representation is broad and well-organized, with a convincing perception of depth and stable positioning of individual performers. Even during longer listening sessions, the EVO 400 maintains a fluid and pleasant setting, capable of engaging without causing fatigue.

The Ultralinear mode provides greater energy, control, and dynamic openness. By selecting the Triode mode, the reproduction takes on a more intimate, soft and harmonically rich tone, particularly appreciated with jazz music, vocals and acoustic instruments.

Adaptive AutoBias: automatic management and protection of the tubes

The proprietary Adaptive AutoBias system greatly simplifies daily use of the amplifier, eliminating the need to periodically perform manual bias adjustments.

The circuit constantly monitors the behavior of the tubes and optimizes their working conditions, helping to maintain uniform and reliable performance over time.

Should a tube present an anomaly, the protection system intervenes promptly to safeguard the internal circuitry. An LED indicator also allows you to quickly identify the affected tube, making it easier to replace it.

The Adaptive AutoBias has been developed to operate without compromising the integrity of the audio signal, allowing the EVO 400 to retain all the transparency, naturalness and musicality that characterize PrimaLuna tube amplification.
