in my experience surge protectors of the sort you might use on your computer have a significant negative impact on sound quality. industrial/hospital grade surge protectors have a slightly lower degree of negative impact but are frequently quite noisy, requiring them to be placed well away from your listening room.
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?
