I have the JPS Power AC (not the +) and the digital AC. I compared them to the Anlysis Plus Power Ovl, the TG Audio Silver and the Auddience Power Cord. I prefered the JPS cords. There is a very good review of the Analysis Plus cord in SoundStage where the reviewer found the cord to have emphasis in the upper and lower frequency extremes, as I did. The TG Audio is a very good cord and maybe a bit faster than the JPS but overall I loved the JPS midrange and longer decay of notes. It has sounded like the mikes that recorded the music were in different positions with the JPS. Drums had a ring to them like the mike was closer or inside the drum, same with cymbals, very natural and smooth. Vocals like Pat Barber came from a very dark background, very smooth, and had a longer decay. I also compared the cords to the Custom Power Companies Model 11 but that cord made my system sound very muddy in the bass.
I have not compared the higher priced JPS cords but you cannot go wrong with the entry level cords for the used prices they are selling on the Gon.
