Yes, using a 10uF lighting capacitor, a small X2 rated cap, and Y rated caps across L+E and N+E. I also used a couple of varistors to help supress spikes.

The sound warmed and richened up, and spaciousness seemed to improve.

(isolation transformers seem to make a larger difference to the sound, but can introduce compromise.)

Ah yeh, sorry, I wasn't clear.

Just saying really that I made a basic filter, it improved the sound, and if you want a more powerful effect, you may have to introduce a series component - transformer, or inductor. But that will cause problems/trade-offs for bass quality and dynamics in some amplifiers.

That's true, some people like the sound of a little RFI.

While others may think that's a joke, John Atkinson of Stereophile magazine wrote:

I think that what the listener perceives with this cable is that at low levels, the sound is fattened and made more coherent-sounding by the dominant second-harmonic distortion. In addition, the presence of background noise cannot be dismissed, as there is some evidence that introducing small amounts of random noise results in a sound that is preferred by listeners. At higher signal levels, transients are accompanied by bursts of higher harmonics. However, these subside as quickly as they appeared. The overall effect is to render the system sound as being more vivid,

Which means that subject statements like "screw up the sound" only have meaning to others when accompanied by measurements.
