I've got a Digital American on my Mac Mini where it made for a surprisingly large improvement. Prior to that it was on my DAC (EE at the time) where it also made a significant improvement. When I switched it to the Mini I replaced it with a Digital HC which produced another large step up in sound quality. Amazing cords!
Funnny you should say that. I have found as well as my customers that the HC Digital American clearly surpasses the Std. Digital American with every component from front end to sub amps.
IMHO this cord is the best cord in the line under the Obsession.
If you own Std. Digital American step up to the HC version and be happier. Yes more money but worth every penny spent.
This cord is a freak meaning just not just better but a transformation.
