You won't have to worry, about the surge protectors, interfering with the sound. I can see conditioners, degrading the sound, but surge protectors should be totaly "safe"! I am using Ulti-mate "industrial" line filter/surge protector and API FL 313 AC cord, with very good results.
Surge Protection and line conditioning
I just had a negative experience with a line conditioner and no longer want one for my system. I heard a little more detail but at the expence of my soundstage and an overall thinning of the music. Anyway, I would like to know if a surge protector without line conditoning would be the right choice if I want protection without the line conditioning. In short, do surge protectors generally leave your sound alone?
