The features of Norma REVO PA-150 make it an extremely versatile power amplifier. Its high power of 150W/8Ohm give it the ability to drive the most demanding speakers and its high quality sonic characteristics make it unique in the world of high-end audio. Power, dynamics, speed and transparency combine, resulting in a total lack of listening fatigue and an outstanding musicality. These features make it a perfect match with the Norma REVO SC-2 preamplifier which expresses the same sonic palette and free flowing sophistication.

The Norma REVO PA-150 can also be a perfect partner for other preamplifiers. For example, matched with the best tube preamps, the REVO PA-150 can drive the speakers without introducing any harshness in the sound or listening fatigue often present in solid state amplifiers, allowing the true nature of the preamplifier to be experienced.

The internal workmanship is extraordinary and highlights a technical refinement that follows the same philosophy. The REVO PA-150 uses proprietary circuitry, a regulated high-speed power supply, low noise architecture and is built with a careful selection of the best available materials. Norma audio pieces possess a sophistication of sound that is extraordinary at any price, embodying the designer Enrico Rossi’s technical talent and somehow infusing the culture and musical tradition of Cremona.
