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?

what were you really anticipating in the improvement?  You can get much better permanent improvements with upgrading power supply capacitors and resistors, AC filter chokes, etc.  A power cord cannot touch those kinds of upgrades.

 

Happy Listening.

Many Years ago when CES was the place for high end audio, I got to meet Nelson Pass and asked him his opinion on power cords.

To the best of my recollection he told me he put a resistor in series with the AC inlet so that the power cord wouldn't matter.

 

My experience is that Power cords are the easiest to hear make a difference compared to other cable types, Digital cables next etc.

We should agree to what "lordrootman" said/thought.

Even $100 power cord is not necessary.

I love to listen to music, not snake-oil like expensive gears.

When you put an expensive part to your audio system, your brain has already inclined to false sense, which mandates " the sound should be better now, yeah, better, ..." Very sad. Sad audiophiles. But,  happier snake-oil makers!
