Power Cords with built in RF reduction?


Which power AC cables have actual built in RF noise reduction filters?

Thanks

Maple Audio's Purity and their Supreme. The Supreme actually has 2 in-line. The IEC end has the RF filter and the other end (plug end)has a "conditioner" that keeps the voltage and frequency constant.
If I'm not mistaken, Audioengr makes power cords with filtered ground, but not cheap...
www.graniteaudio.com with toroids each end for high frequency noise filtering. I use 'em and luv 'em.
