Is it all in my head??


So I bought a Kimber Power Kord...  yeah, yeah, but it looks prettier than stock, is well built, and having built all my cables myself I appreciated the craftsmanship.

...so, I'm playing an Everest LP--symphony stuff.. and it always sounded noisy and muffled (which is why i decided to give it a spin).  The power cable is plugged into my furman conditioner, and all the other cables are the same.  I swear this LP sounds more "untangled" now (that's the best way i can describe it).

I am an engineer and know intellectually this makes zero sense--is it some confirmation bias?  How can it be.. i didnt buy it expecting a sonic impact, i bought it because i couldn't make one that looks as cool (think of it as a necklace for my rig).  But I swear I think i hear a difference...  tell me it's all in my head.

Power cords do impact the sound.  I was skeptical at first too, but after hearing the difference, I know it's true.  You will get to hear more difference the more stock power cords you replace in your system. 
Confirmation bias is a powerful mental force! Since you were subconsciously expecting a positive result, you indeed had a positive experience! 
Now if someone snuck in overnight and replaced that new PC with the cheap original one (and you didn't notice), it is most likely that you would not hear any difference from the day before!
@roberjerman:  Exactly!!  I think I agree but i think there might be more variables at play... for example, I think the act of moving the equipment and ensuring everything is "connected" might in itself clean off enough oxidation that sounds seem "fresh"?  Actually that is a good way to describe it too...it sounds like someone changed the sheets. :P
