I have now clocked 300 hours on the AC-12 power cord to the dCS Puccini player and here's my 2 cents' worth. The AC-12 as it sounds now is indeed a most extraordinary power cord. I never expected that my system could improve so much with just one power cord to the source.
The soundstage is deep, wide and layered in a most natural way in that there are spatial cues at every point in the soundstage which seems to fill up with music all over the place. Bass is deep and powerful with excellent pitch and definition. Listening to double basses is revelatory in that every player with his instrument is discernible within the soundstage. Midrange is silky, solid and vocals image so well that it isn't just the sensation that she is in the room but that you can tell if her head is moving ever so slightly to the right or left of the microphone. Highs are airy and extended, with very good decay of notes. Listening to the piano and all the notes from the lows to the highs is an experience that is jaw-dropping and exhilirating, connecting you to the music and the intent of the performer in every way.
Of course, part of all this observation can be attributed to the source and the synergy with the rest of the system. What this goes to show is that the AC-12 is in great synergy with the source, and so is the source to the rest of the system.
