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

+1 Cundare2,

I replaced my stock power cords with Pangea AC9 MKII SE with Cardas copper (yeah I know they are above average at best) and heard no improvement. I later had 2 dedicated lines pulled and installed audiophile receptacles (Furutech GTX-D gold and rhodium) and Oyaide R1, and voila!.....now we're getting somewhere. Afterwards I went back to the OEM cables versus the Pangea cables, and now there was a sonic improvement.

My conclusion is that only when I upgraded my power delivered to the cable, was the cable able to produce a difference. As I am now building a dedicated listening room, the first thing I will include is 3 dedicated circuits.

They don’t make difference unless the gauge is too low and they are starving the component from power. Higher price tags and pretty packaging won’t change that. 

@tennisdoc56 +1! At last a reality-based response! 

from  tennisdoc56: By what method/electrical theory does a power cord improve the contractor grade romex in your walls?   Please avoid explanations in biology such as sees, senses, feels, prefers.   Not being sarcastic 

I googled the following:  "acoustical properties of various metal conductors" and over the next 6 pages, I didn't get a single hit that covered, in any manner, the way that each metal affects the sound of the signal that passes through it.   There were entries about sound absorption, sound reflection, which metal is the best conductor of electricity, acoustic properties of commercially available thermal insulators, and the speed of sound in metal/sound waves passing through solid metals.   

Nowhere did I see any mention of how passing the signal through various metals affects the sound.  There was nothing about the warmth of gold, the detail of silver, etc.  Is there respectable research being done in this area; are theories out there relating to this?   I have no idea, but my search didn't yield anything relevant.   I'm not a scientist.  I'm actually quite challenged by modern technology, but I do use the scientific method in my audiophile pursuit.  I LISTEN.  I try different components, cables, connectors, and most recently, slugs (in place of fuses).  I don't know WHY there are such variations in sound between the various metals I've used but, clearly, the addition of different metal(s) in the signal path (and possibly outside in the case of some fuses) can significantly affect the sound.  

Rather than rely on this stance, why don't you simply experiment, and listen.  Do you really think that all those stating the benefits/differences of cables are delusional or just exaggerating?    And please tennisdoc56, don't take this as an attack.  Since the research doesn't appear to be out there, I think we should all do our own.
