Norma Audio Revo PA-150 Stereo Amplifier

Norma Audio Revo PA-150 Stereo Amplifier

The REVO PA-150 is an extremely versatile power amplifier offering high current power (140W/8Ohm) to drive the most demanding speakers. Power, dynamics, speed and transparency are combined to make a total lack of listening fatigue and outstanding musicality. These characteristics make it a perfect match with the REVO SC-2 Preamplifier which expresses the same sound personality. For people who want to combine it with other preamps, the REVO PA-150 can become a perfect partner. It uses proprietary circuitry, a regulated high-speed power supply, low noise and is built with careful selection of the best available materials.


  • Extreme low noise, high speed schematic topology and wide band ( >2 MHz ).
  • Separate power supply for Gain, Driver and Output stages.
  • High speed and low noise regulated power supply for gain and driver stage.
