By "RF noise," I don't mean just external broadcast sources. Many things inside the house can generate substantial electrical noise in the frequency ranges of audio through UHF: the noise you hear on an AM radio when a light dimmer is operating nearby is one example.My personal noise devil is the switching power supply in my wife's digital video recorder. We had a TiVo machine, and when it died following some power surges my audio was heavenly. The replacement was not quite as bad, and I think I've mostly brought it under control with some treatments to the AC supply to the DVR.
I have a friend with SoundLab speakers, and we heard quite an improvement when I put a couple of my experimental power cords on his speaker HV supply inputs. He has an AC regenerator to operate his digital source and preamp, and my cords did nothing to improve his sound on these components. This leads me to believe part of his noise problem is RF broadcast by the cords connected to his HV supply, or conducted into his power amps through the AC wiring. Other electrostats may have better HV supply filtering and not respond to RF suppression on the HV supply AC cords.
