For over one hundred years people believed electrons flowed like water through a pipe and that once "contaminated" by miles of wire, there was little or nothing that could be done to 'clean' the electricity feeding your components. Consider this: the electricity feeding your systems components first propagates through a single fuse. This is why significant gains are possible when you insert a Blue Fuse into each of your components.
Today physicists understand electrons don't flow at all but rather propagate in a wave of energy that moves along a conductor with a multitude of factors that alters this wave at the quantum level. To understand how electricity travels without electrons ever leaving their respective atoms it is helpful to consider the spectator wave at a football match. Even though you can clearly see a wave pattern moving from spectator to spectator as fans raise and then lower their hands (without hands jumping from one person to the next), so too does electricity ‘move’ without electrons ever leaving their atoms. Synergistic Research have isolated key factors that affect how electricity propagates by changing the behaviour of electrons through Inductive Quantum Coupling methods we collectively call UEF Tech. In fact, UEF Tech is so powerful even an electrical chain several miles long is fundamentally improved with nothing more than a single fuse engineered with there patented UEF Technology.
On the other hand, maybe there are folks who believe this stuff. I remember years ago some people swore that green markers would improve the sound of an audio compact disc.
