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 OP mentioned Shunyata Sigma was the power cable. I think that post was removed. Not sure what $500 power cord he’s using though.

I assume you didn’t spend several thousands of dollars on a 5 feet power cord without installing a dedicated 20 amp circuit with 10 gauge wires from your panel?

Otherwise, what difference will the last 5 feet make?

@bimmerlover I have to question the thinking that it's the last 5 feet, the equipment draws the current, so it's the first 5 feet.

@invalid The electrons don’t care if you or I call the power cord the last or first five feet in a circuit that also involves 10 to 40 more feet of in-wall wiring.
