Active shielding. What is?

Greetings Bigtee,

The only current flow in a circuit that the Synergistic Active draws would in the regulator(power supply) circuit it's self.
Since the Active shielding only produces a charge potential(open circuit).
Due to the fact that close to no current flows in such a circuit, the ripple (even with that scrawny supply) is almost nonexistent.
Nonetheless, an upgraded supply could not hurt.

the current is only just enough to light an LED: 10 to 20mA DC

The shielding in this cable makes a complete circuit from top to bottom. It has a wire that runs the length of the cable and comes back to source. Anytime power travels through a wire, it creates a magnetic field. I'm still back to the question of the purity of the DC since it is a complete circuit along the entire length of the cable. The AC ripple is going to have an effect.

I also meant to include this in my last blurb. Bob, you stated that the power cord would make a difference in the sonic signature of the cable. I hope this is not the case. Once you convert to DC, there should be no sonic signature. If there is, well, then my question is even more relavent.
