I've heard a significant reduction in noise and improved definition and subtlety in a friend's audio system, since he started using a Monster Power conditioner (model 2000). He has very noisy power coming into his house, attributed to the school across the street from him and a power substation nearby.
My power is not usually as noisy, and I have solid state amplification (my friend uses tubes), but my cable and power lines have been hit by lightning. So, for $125, I'll also soon get the Monster 2000 and hope for some audible improvement, along with the lightning insurance.
