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?

The there is always the option of changing the amp. That will surely change the sound of the power cord. 💡

I prefer my Pass XA160.8 (as well as my previous Pass X250.8) with Cerious Matrix and Lumniscate  power cords. According to Stereophile (and others) Pass Labs uses Silent Source power cords and cables to voice their products and present them at audio shows...

I own Pass phono stage, headphone amp. Used to own several power amps, starting from Aleph. I use fairly simple cables, properly shielded, soldered and have sufficient capability to deliver appropriate current without picking up additional RF interference. In $100 price range.

I generally think “what would be used in a fighter plane electric power delivery system”…

@eurorack of course if you change from a substandard, “crud” power cord to something that’s half decent you should notice a difference. That’s obvious. Crap is gonna limit anything in this world - power cords or not.

What we discussing in this thread is if there’s a difference between a $100 power cord and a $500 power cord and a $4000 power cord.

 

That’s very different from the experience and situation you are referring to, I think.

     I'm fairly certain; very little critical audio listening goes on in fighter planes.

     However: here's something that NASA selected, to conduct power, for their portable LASERs.
