Reb if your digital source has stock cord and can be replaced I would recommend Pangea ac14 series for that.
Different cords from vendors like Pangea specifically have different designs for different problems. Some targeting line level gear that do not draw much power and others targeting power amplifiers that do.
A set amp operates in class a and draws a lot of power from the line continuously as I understand it. So I would expect you want a power cord designed for that kind of amplifier specifically as al indicates.
The Pangea model for amps I'd the ac 9 line which costs more than ac 14 for line level gear. The Pangea cords are very good build quality and design for the task at hand. Ac 9 would likely be the one you'd want there for an amp that draws a lot of power. I'm sure there are other good ones that set users can vouch for based on experience. I plan to add ac9 cords to my class d amps someday. I suspect they would have a positive effect over stock cord in your case but cannot say how much or what's "best".
