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?

I will be testing this soon on a Pass amp as well. So this thread is definitely interesting. What I can say is , Ive noticed quite a substantial benefit when I upgraded PC's for my streamer dac, Preamp and older Integrated Amp.

I tried and absolutely did not like Shunyata Alpha NR v2 on pass amp. Never heard the Sigma. As someone mentioned earlier in the thread, not every “upgrade”, be it a component or a cable, makes a positive difference or even a difference at all.

And some times leaning on I told you so will start another cable war leading to deletion lol. But I told you SO…. Placebo, in this case that didn’t even work !!

@audphile1  , I don't have a Pass and that power cord is out of my league, but from your statement above, I assume that you did hear a difference?  What was it that you heard that you did not like?

Everything matters! Is it cliche? Yes, but true  A dedicated line or 2(preferable) with upgraded receptacle(s) are a must to set the foundation. I don't want to comment on specific brands but if not able to have a full loom(Ic's/Speaker cable/Pc's) Keep the same brand of Ic's and all Pc's should be from the same company.
