PrimaLuna EVO 300 tube power amplifier - silver

The PrimaLuna EVO 300 is a tube stereo power amplifier designed to offer high sound quality, extremely accurate construction, and reliable operation over time. The internal circuitry uses entirely hand-made point-to-point wiring, with generously sized conductors and carefully selected components. This solution allows for a clean and direct signal path, minimizing interference and noise.

Among the most important technologies is the Adaptive AutoBias system, which constantly monitors the correct functioning of the tubes and automatically adjusts their bias. In the event of an anomaly, the circuit immediately intervenes by activating the amplifier's protection, preventing the failure from affecting other components. A red LED, positioned next to the affected tube, allows it to be quickly identified.

The Adaptive AutoBias system operates completely passively, without interfering with the audio signal. In addition to simplifying tube use and replacement, it helps extend their life and significantly reduce the need for adjustment and maintenance.

Power is provided by specially designed toroidal transformers, enclosed in metal cases and treated with a non-microphonic resin. This particular construction helps contain vibration, hum and unwanted noise, ensuring quieter operation. The metal shielding and resin encapsulation also offer additional protection against humidity and deterioration, promoting stable and reliable performance even after many years of use.
