I think we are back again to the issue of the dedicated AC lines and what external (outside of the home) garbage can enter through them. My own anecdotal impression is that there are two opposing trends from the power company. One is positive in that they are replacing old equipment. On the negative side increasing digital monitoring devices are throwing more nasty garbage into the powerline. (A good question is how far such noise can travel from the source.) I think Romy when he was measuring such things a year or two ago encountered bursts of extreme powerline noise. But then they would suddenly disappear. Since the dedicated line minimizes within home pollution it should be ok in the good days. I have seen comments at other sites where people moving to the dedicated line felt that solved their problem and they didn't need the AC regenerators. For myself, I would say my (old version) PP unit mostly evens out daytime and nightime audio system performance rather than making some more fundamental change. It's probably more essential in countries which have Very unreliable power grids.
