Rerurn to Romy the Cat's Site

Anyone familiar with these? http://www.vertexaq.com/component/option,com_frontpage/Itemid,1/ 
I heard a demo @ RMAF; without, with, without again... 
Very effective. 
In that place, At that time, with that system, etc.  

Part of it is about electrical problem, part about vibrations getting into electrical components. 
I did try the "listen to end of wire through stethoscope while rubbing with penny, hear horrible scratchy noise, change to their wire with "magic box" and the noise went away." 
How that could affect SOUND, I don't really know, don't know if I buy all their explanation, but it sure made a huge difference. 

The typical bad electricity/good electricity difference, so I thought I'd mention it here, even though I don't understand what I heard...
