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.
