Review on πŸ”‡ Pyramid NS20: Advanced 15A RCA Noise Suppressor for Clean Audio Signals & Noise Elimination - Built-in Isolation Transformer, Ideal for Amplifiers & EQs, Easy Installation via RCA Jacks & Unique Noise Detection Circuit by Kenneth Wood

Revainrating 5 out of 5

Really works in noise filters

This unit works really well with my 1500 watt amp. It completely quashed the noise of the hum I was hearing. I had to buy (2) of these. One for the front speaker inputs and one for the rear speaker inputs. They didn't spoil my sound quality. At low or high volume, the sound is perfect, without hum.

Pros
  • Solid build
Cons
  • So far so good
