Quick power cord question:

I just read a partial prereview of a new product out that emits DC through skinny wires that wrap around a power cord to prevent RFI from affecting it. The reviewer went on to say that that's what AudioQuest has been doing for years with their batteries attached to their cables, along with some other manufacturers.

I have no dog in this fight but it brings up the question that if it was no biggie then, it's no biggie now, so why all the hubbub?

That reviewer doesn’t understand the premise of the Audioquest/DBS system.       It’s spelled out in their patent application, for which I posted a url earlier.     

Well, that reviewer may not be aware of that patent, but it sure as hell looks like what he’s mentioning when he refers to AQ. I’ve seen one of their demos up close (there being only the rep and the two of us listeners) and it mirrors remarkably like what the reviewer described.

Here’s the pre review of the device that I saw today:

What difference does what it, "looks like" make, if he’s WRONG?    The patent application spells out the goal of the DBS system.   ie (verbatim): "FIELD OF INVENTION

The present invention relates generally to methods and apparatus of connecting and communicating signals between electrical devices. More particularly, the present invention relates to biasing a dielectric with an electrical or electrostatic potential to reduce undesirable electrical properties of the material such that signal quality between the electrical devices is enhanced. The invention has special utility within the field of audio and video equipment and signal transmission"     The balance of the application contains nothing about RFI, but- everything about how the DBS system is supposed to enhance the transmission of various signals, by the biasing of a cable’s dielectric.        Too bad so many are too lazy to bother reading, educating, or- informing themselves, rather than trying to be contrary.    This conversation has become tedious.    I’ll leave the ubiquitous last words to others.     Best regards and happy listening, everyone!

More particularly, the present invention relates to biasing a dielectric with an electrical or electrostatic potential to reduce undesirable electrical properties of the material such that signal quality between the electrical devices is enhanced.

It doesn't say or mention what is biasing the dielectric.

As for reducing undesirable electrical properties of the material, that can be another way of saying that it's making it (the dielectric) resistant to RFI without the need to spell it out, rendering the patent moot so others can't copy it.

And, in that link you provided, AQ states that they finally found a way to use DC as a shield to reject RFI and EMI, so where did I misunderstand things, and just where did the reviewer get it wrong as well?

How you can read into it that I am being contrary is just plain silly.
