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?

2. If you deem a $500 power cord expensive, it's pretty safe to say your system is fairly entry level.

@roxy1927   , did you upgrade FROM a $500 cord, or did you upgrade TO a $500 cord?

Yes my amp is a stereo Pass 250.8 and the manufacturer said don’t bother. I originally had a $500 going into the Pass and replaced it with the expensive cord. I don’t think my system is entry level. Maybe mid. I am going to place the expensive cord in various components such as my Dac and transport(both Ayon. I bought into the never ending advertising but people had positive things to say and I'm very happy having purchased them) to see if it makes a difference there. And though I may not have the most discerning of ears I like what the Shunyata sigma did for my ARC pre. Can I tell you what it did exactly? I don’t know really. But I liked it. I know lame. But maybe it gave it a bit more punch. It made me like it the component even more. I’m sorry but I’m not an experienced audio critic who can describe nuances. But with the expensive cord into the Pass as they say I felt(heard)nothing.

@roxy1927  , thanks for clarifying; I thought I knew what you meant but I wasn't positive.

When you got the Pass did it have the OEM cord, or did you have the $500 cord already installed when you got it?

If it came with the OEM cord I am really curious as to how much difference you heard when you put the $500 cord on it?

Can I tell you what it did exactly? I don’t know really. But I liked it. I know lame.

Actually I can relate to feeling that way about an upgrade.

The fact that you are not hearing that with the 'several k' power cord kind of makes me think you were not hearing confirmation bias with the previous upgrade you referred to.

I'm going out on a limb and saying you didn't hear any difference because there WAS no difference! Sigh...so much money wasted on silly  aftermarket cords.
