I owned a CH Acoustics X-20 power cord some years ago, bought after demoing many other power cords. I chose it because it was very open sounding -- extremely clear and fast sounding, about as far removed from a tone control as one can get. I seem to recall it needs to be plugged directly into an outlet, not a power conditioner, to sound its best -- at least that is what Craig Hampel recommended. I ended up buying it to power my transport. Once I sold that and replaced it with a Mac mini, I also sold the CH Acoustics power cord.
If you are looking to add warmth or for enhanced bass, CH Acoustics isn't a great choice.
