I think you really nailed it. If they do work, what does that say about the power supply?
Many power supplies are unregulated, they use a step down transformer, diodes and a few filter caps. More sophisticated supplies have regulators. Regulated supplies have filters (capacitors) after the regulators. Obviously the regulator should filter to a voltage, thus removing any external variation, and the additional caps should better filter.
Unfortunately we do not live in a perfect world. Caps have ranges within which they work, best at the center of the band. They generally do not filter out everything. Regulator help, but they too pass very high frequency grung which often muddies the mids. They are better than nothing, but they are not a complete solution.
That means that external filtering CAN help, but it does not mean it will. That would depend upon a lot of different factors. I tend to go for cleaning up the power supply. I generally begin with Fairchild Stealth Diodes. Then I use either .1 or .01uF Teflon or RT Rel Cap Styrene by-pass caps. Teflon is best, but a .01uF cap can cost as much as $40 + dollars. I will often replace stock caps with Black Gates, Nichicon Muse, Elna Silmics (sp?), or Panasonic FC's.
That will generally clean up your DC. Tefon rules, but RT's are a best buy, and do come close.
