One point : the plug is not the only thing that makes the sound of CD more analogic than most other power cables with the digital AC JPS, as I had to change the plug for the european voltage (and not with another special JPS plug).
Anyway, my CD/SACD player sound softer and more analogic with the jps digital cable without its original plug than with any other power cable I have (Audioquest, Cardas, Shunyata).
The benefit is clear in that way, but it depends a lot of the entire system - other cables, for instance.
If your digital player already sounds not harsh, too bright or kind of agressive, well it could be too much to use that cable : it could may sound the CD's too soft, restrained, dark.
