audiphile power cords

(1) Yes
(2) Without knowing the rest of your system including inter alia, source, all electronics, speakers, AND all the other cables in your kit, it is impossible to blindly recommend one. Choosing one blindly is a gamble at best. Without knowing more, all you can get back in these blogs are heavily biased personal value judgements that are functionally useless otherwise.

System synergy matters ... big time. Just because it sounds good in one guy's rig is no basis to assume that it will sound good in your system. .

There is no substitute in:

(a) first doing your homework for YOUR system requirements; and then
(b) also doing actual in-house auditions to swap them in and swap them out

to see what sounds best. There is no other magic bullet. Good luck.

play with one with return policy. if you don't hear differences, you've just saved lots of money you can purchase media.

They definitely make a difference in most cases but not always necessarily better. I have tried enough in my system to determine stock cords are better sounding to me. YMMV.
