I hesitate calling what the Power Plant did to my system as imparting a particular sound. When I investigated different standard power conditioners, I found that all improved the sound of the system in one way or another, but all had a certain personality. One unit would make the system sound brighter than the other would; one would impart a burnished character, while another would make the bass sound a bit thick. And none of them would allay the problem I had of the system sounding better at night than in the daytime.
