@ricred1 - I don't know that the older Audioquest power cords were that bad. The cord itself (such as NRG-4) is very good, but a significant amount of the sonic signature is also determined by the terminations, which were typically gold-plated. An excellent high end cord terminated with gold-plated plugs will sound very nice - it will hit with authority and weight, but it will just not have as much attack and detail as a rhodium connector. Silver clad (like the Wire World) can help things. But once you get into silver / silver-plated stuff it will push the sonic signature towards the "silver" character.
There are definitely some exotic designs out there (High Fidelity, Verrastar), but I still focus on what they use for terminations.
