Let's talk power cords

Can someone who has had positive experience with aftermarket power cords cite specific examples of what they heard? Which album? Which passage? What specifically? Was it really "better" or, just different? If it was"better", what do you think was causing that deficiency in your system in the first place?

Better is always going to be in the ears of the beholder. 
Good systems aren't deficient they will produce music differently with a variety of different power cords but I don't think it can be proven to non-believers satisfaction because it's a matter of personal taste and hearing ability.

Agreed but trying to get more insight into what people perceived to be as better. For example is there more Bass, is there less sibilance in the vocals, are some of the highs less screechy,.

@pawlowski6132 I understand your desire to gain info about cable characteristics from others. It’s kinda circular, as that information relies on gaging and aligning the contributors’ subjective listening (and hearing) impressions with your own. And I hazard to suggest this quest is further complicated (and frustrated?) by objective differences in audio systems and room acoustics.
