I came across the following "infomercial" on the Chang Lightspeed web site, and wondered about it. It never occurred to my non-technical mind that my Sound Labs could pick up RFI and send it back into my other AC lines in the fashion described, resulting somehow in poorer imaging from the speakers. Does this make sense to any of you technical types, or is it just another "infomercial"?
"Electrostatic loudspeakers, considered by many to be among the fastest and most detailed speaker designs available, require their own own power supply to charge the speaker diaphragm. The charged diaphragm acts as an antenna picking up RFI from the air and injecting it through the speaker power supply's AC cord into the house powerline. This contamination reaches every component and electrical device in the house via the AC main junction box. Audible results include confused imaging, brittle highs, thin bass and a shrunken sound stage.
The cure is to isolate your electrostatic loudspeakers from all other equipment with a dedicated Lightspeed."
