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.

+1 mrdecibel. It is nice to hears the sincere comments from ones like you and elizebeth and others. Not letting the other negative comments be responded to, because it changes the focus on the fine exchange of good thoughts. Just ignore the negative posts, as it always takes the discussion in a different direction.
And for the OP. Yes it is all in our head That’s where we perceive things, in our head. So it’s ok if there is no technical reason for what you hear. There are qualified individuals that say we cannot measure everything we hear. Just enjoy it. And thanks for sharing your thoughts.

Great post MrD! I especially like the way you described how  you settled on horns. I am not a horn person as my journey and preferences took me in another direction.

I would ignore the naysayers (and they are not all created equal) but sometimes the information they provide is presented as fact and may influence other enthusiasts perhaps discouraging them from trying new cables and products. 
Thank you guys. " But sometimes the information they provide is presented as fact ". Yes, they present it, but they are not proving it. They are the ones looking for proof, for reasoning, for scientific data, as to why we are claiming sonic differences. Fact ! I know what my ears / brain tell me. Lizzy, Geoff, myself and others, will not be fooled into the " could I be imagining it " camp. Which is a point I made. Ignore them, because, they will continue with their pursuit. They question our hearing ? How about our taste buds. Vodka ( my go to ), each brand having a distinct taste. Is this, the fact I can taste the differences between Absolute, Grey Goose, Tito's, Smirnoff, etc. real, or my imagination. Now, in reality, I can probably be fooled into mistaking 1 brand for another. Sight, smell, taste, touch, hear. Hearing, is definitely my strongest and most developed sense. Enjoy ! MrD.
Happy New Year All

Normally I wouldn't knock a manufacture but since one keeps being mentioned as being good I have to disagree .
Pangea did not sound good to myself or a friend ( who rebuilds guitar tube amps ) , that includes both the power cords
( we tried both 14 and 9 gauge ) and the power outlets .
Pangea has 3 grades 
We did an experiment with 4 different outlet manufactures  and
the Pangea lowest grade  came in 3rd .
So like all equipment and cables/interconnects what might work for some doesn't work for all .
