Those that dismiss power cords will say that if the gear has a well designed power supply the cord does not matter.
What I think they forget is... if that well designed power supply is fed inadequate power, it will have to work hard to make the gear perform, no matter how good it is made.
There is also the garbage in theory of course.
A power supply can always be better. There is always a price point in the design. If a better cord makes the power supply's job easier, then the sound should improve.
Why do you think they have "hospital grade"? Do you want a cheap power cord and wall outlet on the respirator keeping you alive?
