New expensive power cord for amp and no change in sound?


I bought new an expensive(for me) well known and reviewed power cord for my very good amp and plugged it directly onto the wall socket. After a couple of weeks of daily use I hear no change in the sound quality from a $500 cord. I don’t want to name it for fear of getting my thread deleted. You would know it or at least be aware of the company. Did I throw away several thousand dollars? Before I get the snake oil answer I want to let you know that I bought an upgraded cord for my pre as suggested by the pre’s manufacturer and am pleased with the results.

I guess for full disclosure the amp’s manufacturer said don’t bother. But I had had good luck with the pre so I thought it would be a good idea.

Anybody else have this happen to them?

@mapman +1M! the best comment ever! "The there is always the option of changing the amp. That will surely change the sound of the power cord"
@phd "Power cords can make a huge difference. This difference can be on par with buying a new amp (component upgrade).” (-) in your bank account!

""Have you tried an after market cord?”

- Yes many times, the first one about 25 years ago.

"why?"

- I was curious about the products and most units came with detachable cords to make it easy to do so.

I didn’t read all the post so if someone mentioned this. You stated in first post “after a couple weeks of daily use I hear no difference”. Does daily use mean you are not running cord 24/7? Even if you are running amp 24/7 300 hours may not be enough to burn in your cable. If it’s not run in it will sound thin.
