What was the first power cable that you noticed a difference in the sound?

In a good system a $2K Audio Quest Hurricane can be a bargain for the amount of sound quality gained for the money. 
 

This is the whole reason high end wires are around, for a person that chooses wisely, he will always be getting a bargain for what ever the cables cost.

I remember having a system at the $5K / component level and my dealer sent me a set of cables costing $2K… I thought that was simply ridiculous, until I heard them. I could not have gotten that improvement by swapping components for less than $5K. The sound quality improvement of any given component (wires included) needs to prove itself. One of the important steps in high end audio is to put in the time to learn what is worth it given your values and system.

Some of the more "esoteric" aspects of cable materials, layup, etc (and impact on sound) can come into play for analog interconnects and speaker cables. For digital cables and power cables, sufficient noise dissipation and shielding is the only thing that impacts sound...senseless to pay an arm and a leg for the latter as it can be accomplished at a very reasonable cost (no killer r&d crap required).

Anyone tried Audio Art power cables?  
 

Thoughts?

Black Cat Silverwolf Power Cable

@elacross ,

Any idea when they stopped making the Silverwolf PC and what a good price would be on the used market?
