Frequencies addresses by power cords?

Thanks Al. Misprint. s/b frequencies "addressed".
As in what ac "line noise" frequencies do the various top line power cords attempt or claim to eliminate. Equitech "seems" to state to 100,000 hz as they mention other filters operate above 100,000.

Thanks Atmasphere. Interesting. I thought the distortion didn't contribute much to the power output. In fact I thought ac distortion was a negative factor. I've seen so much about using REGENERATION to provide a smooth waveform and therefore more usable power? And I thought all conditioners were basically working towards this goal. By the way I don't think ac power supply is going to improve anytime soon. any thoughts?

Well Al, what does this mean for power regenerators?

Safe comment - unpredictable :-).

Thanks Don, more detail would be helpful. I'm most interested in MIT, Shunyata & Equitech. (These mfg's don't provide detailed specs; although I can't imagine why. If they are proud to build it--they should be proud of what it does.(High-end has had enough "magic" & "flooey dust"-not to mention "magic anti resonance dots-wow, that's a great one) over the years and I am certainly hoping our tech advances will soon make "magic" a thing of the past.) I want to create the most effective "blend" of conditioners and power cords. Of course I'm doing well by ear, thanks to Ref Spectral & MIT gear-and an Equitech 2Q providing a basic isolation/cleaning of AC, creating adaquate depth of detail and clarity to analyze the sound I have, but in classical music I enjoy how more details bring me closer the the artistic creativity of the composer, the director and the individual genius of the players, not to mention the ambiance and silences.
