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

"I’ve tried numerous power cables from $300 to $2500,"

- So, what did you do with the numerous power cables from $300 to $2500?

Welcome to the forum. Thanks for your comments…

However,  without context it is hard to gain any insight. What are your components and venue. There is a place under your user ID to put photos and identify your components. A bit of context is also helpful to understand the conditions of you observations.

I have also tried numerous after market power cords from $100 to $2,500 and found the lower end to have no impact and the upper ones to have something between excellent improvements that were very nuanced to startling improvement.

Borrowed them from the store and took them back

@ditusa Hope you never have a fire, because if you do you won't get dime one of insurance. What you've done is a complete violation of the National Electrical Code, and an adjuster will notice it in a heartbeat.

Its honestly a mixed bag
I put an AQ Dragon HC power cable on a gryphon amp and wasnt sure there was a difference. This is a very expensive cable to not hear much over a stock cable

On the flipside

the biggest difference i ever experienced was when i upgraded speaker cables a while back.I went from plain installer grade wire to a used pair of AQ Volcano. 

it was such a massive difference that i reinstalled one speaker with cheap wire and the other with upgraded wire to demonstrate to some cable denier friends

i even made a video about it where i would go back and forth between the two. It was such a huge difference that even playing it back on my cellphone the gap was so large it could have single handily ended the cable debate as anyone not deaf could hear the difference 

now i run stealth audio cloude 99. Once again this is a big difference. They use a helium dielectric and are ridiculously fast and airy silver cables

it affords me the ability go with more “chocolate” upstream
