My only experience is the present one : with the high quality swiss power conditioner probably nobody knows here in the USA, named "Boîte Noire Reference" (6'000$) I enjoy more the music with my Accuphase amplifier P-7000 plugged into it than into the wall.
There is possibly a slight loss of power (but with a powerful amplifier, it doesn't matter) but a richer, more articulated and less harsh sound. Better, no doubt about that.
