The Norma REVO PA 150 represents the best expression of the classic stereophonic amplifier… a timeless classic! Versatile in terms of use, these electronics can be combined with almost any type of speaker: dynamic, electrostatic, magnetodynamic, high and low efficiency… each of these, in its own peculiarity, will be able to express itself to the fullest of its features by acquiring dynamics, speed, extension, soundstage, but above all bringing the listener closer to the musical truth. This is Norma’s mission! The considerable sizing of the power supply and the very high current available at the output give REVO PA 150 excellent delivery and load control capacity. Its power doubles on a 4 ohm load, so even lower loads are handled with maximum ease.

The features of REVO PA-150 make it an extremely versatile power amplifier. Its high power (140W/8Ohm), the ability to drive the most demanding speakers and sound characteristics, make it unique. Power, dynamics, speed and transparency are combined to make a total lack of listening fatigue and outstanding musicality.
These features make it a perfect match with the preamp REVO SC-2 LN, which expresses the same sound personality.

But, also for people who want to combine it with other preamps, the REVO PA-150 can become a perfect partner. For example, with the best tube preamps you can enhance the characteristics of sound, giving an extraordinary ability to drive the speakers without introducing any harshness in the sound and the listening fatigue often present in solid state amplifiers.

The inside workings show that the technical refinement follow the same philosophy. The REVO PA-150 uses a proprietary circuitry, regulated high-speed power supply, low noise and is built with a careful selection of the best available materials.

Awards& Reviews


Norma is based in Cremona, Italy.

The city and its surroundings are well known all over the world for being home to great composers as Monte-verdi and Ponchielli, and to famous violin makers such as Stradivari, Amati, Guarneri and many others. As of today, more than 100 violin makers’ shops are found in the ancient roads of the city.

In this inspiring context, where music permeates everything, for more than 20 years Norma has been involved in the study and implementation of sophistica- ted audio amplifiers, where technical skills and musical sensitivity must be merged together, in the same way the best musical instruments are made.

The result of this endeavor is a unique sound, which represents a synthesis of parameters usually set one against each other: dynamics, speed, and absolute transparency are combined with extraordinary musica- lity and total lack of listening fatigue.

The struggle between solid state and valves is finally overcome, as is the concept or reproduction.

Norma brings the listener to an intimate relation with the original event.
