I just experimented with few power cords.
PS Audio Prelude, Acoustic Zen El Nino, ZU Cable Birth and Bok models. I have to say that out of all this cable switching back abd forth, I came to this conclusion. It is not worth going crazy with super expensive power cords. In my system these power cords had following effect:
PS Audio Prelude:
With amplifier - better bas, but rolled off highs, midrange was not impressive either. Overall, I wouldn't stand using it on my amp for an extended period of time.
Same power cord on CD player was overall very well balanced with lowered background noise.
Acoustic Zen El Nino had exactly same effect as PS Audio Prelude. Great on CD player, but restricted highs, recessed midrange, but better bas on the amp.
ZU Cable Birth and Bok work equally good with CD and AMP.
My conclusion is that a lot of shielding on the power cord, such as on PS Audio and Acoustic Zen may be beneficial for a CD player or transport, but degrade the sound quality, especially treble and mids, of the amplifier. ZU Cable Birth and Bok are not as shielded as the other 2 cords I tried, so Birth, being a smaller gauge cord, is more suitable for CD and Bok worked really well with my amp.
All of the above is only my findings based on what I heard in my system. Of course it may have a different effect in someone else's system, but, here is my 2 cents.
Also, when you buy a power cord, make sure you can return it, or buy a reputable power cord such as Audience or Shunyata, this way you can always sell it if you don't get a level of improvement you wanted to achieve.
And if it metters, I founs PS Audio Prelude very flexible. Acoustic Zen El Nino was not as flexible as PS Audio, so if you have little room behind you components, you may want to go with a more flexible cord. ZU Cable power cords wer both flexible. Good Luck!
