I have had poor results with "audiophile approved" power conditioners that one plugs into the wall and then their component into the conditioner. There was always a change, however, there was always a change for the worse. There may have been a wider soundstage, but decreased dynamics as an example. I am therefore going straight into the wall. The use of better power cords however, made a huge difference. ALL power cords sound different in my system...even different on different components from the same manufacturer. My suggestion is that you search for the cord that works in your system on the component that is specifically used. As an example, I am using Accrolink with Oyeida plugs on my Ayre C5xe, and Accrolink with Furutech F1 plugs on my Ayre V1xe amp. If I switch the cords, there is a definite loss of detail, and soundstage. The Environmental Protection gizmo provided a slight increase in clarity and soundstage with its protection, yet has no ill effects that I can hear.
