Your experience with these power cables?

with all of them being older, you could search the forums 

using it now ?

if so, what difference did it make ?

can never understand why members will start a thread ( such as this one ) and they want a comparison of said power cords. 

then you find out after the OP replies that they have all 4 already and then got to try them out on different equipment and made their own decision on what sounded good where.

why not just do this in the first place instead of starting a new thread ?

@jsbach1685 

is the Ayre stock pc a typical standard issue cable? Or is it a custom made item for the cx7? 

i thought it was just a typical standard issue cord?

you could always send an email to ayre and ask them?
