Can anyone explain how an improvement in a wallwart used in charging a cable can so greatly affect sound?

I substituted the new Galileo MPC on my SR interconnects and got a sonic improvement that just floored me. How can this be? I can certainly understand how a dc charge on the shield of a cables works to reduce RFI and EMI effects on the signal in cables, but how can a better charger affect the sound?

We are not talking about a minor effect, such as raising cables off the floor or anti-resonance devices on cables.

Perhaps the former wallwart was polluting your AC? (nt) - pburant 07:38:11 11/06/09 (2)
- Yes, that is a plausible hypothesis, if a little transformer, diodes, etc. can have that much impact. nt - Norm 07:53:19 11/06/09 (1)
  - Hey, let's start a thread about how small things can be and still have an impact! nt - geoffkait 08:03:13 11/06/09 (0)
